Waching daily May 15 2017

Hi all, today's video will be part technical and part commentary.

By now you would have heard about NVIDIA's upcoming Volta GV100, the largest GPU ever

created.

At 815mm2, the odds of a fully functioning chip per wafer is very low indeed.

But from each wafer, are a bunch of cut down chips to be sold for $18,000 each as the flagship

Tesla.

When you can price your chips that high, the long established rule book on chip design

can be thrown out entirely.

If you read a few tech news articles on Volta, it should be obvious the major improvement

in GV100 are the new Tensor Cores.

What are they?

Well, in processor terms, there's Scalar ops or single numbers, Vector ops or a one-dimensional

array, and Tensor ops or a two dimensional array, a matrix.

In simpler terms, if your workload involves the matching datatype, Tensor cores can vastly

accelerate performance.

Instead of GV100's 30 TeraFlops of FP16, in Tensor workloads, it's 120 TeraFlops.

At this point, the tech press and readers in general focused on the comparison with

Vega, at 25 FP16 TeraFlops, it simply is leagues behind for the AI market.

However, most ignored the huge elephant in the room.

Google.

They have been running Tensor cores for their AI network a few years already but only went

public recently.

Meet Google's first-gen Tensor Processing Unit, or TPU, a 28nm chip that is ~300mm2,

capable of 92 TeraOps.

All that processing power at only 40 watts total power consumption.

In Google's own words, their TPU is an example of how fast they turn research into practice.

From design, to production, to running within datacenters, TPU took a total of 15 months.

From first silicon to operational, 22 days.

Absolutely staggering.

When we factor in it's die size, power usage and performance, compared to Volta GV100,

it is entirely on another level despite being on an older node.

The main reason why this is possible is because it's an ASIC, or Application Specific IC,

less flexible but very potent given matching workloads.

NVIDIA's new Tensor cores are very much in the same principle, it's an ASIC unit that's

bolted onto a General Purpose GPU.

Volta is the next evolution in an arms race, shots fired for sure, but not at AMD.

This is NVIDIA fighting hard to take the lead in the AI market, the domain of Google who

has publicly stated, their goal is to lead the industry on machine learning and to profit

from their customers.

It is no coincidence Google came out with a public blog just days after Volta's reveal

to extol the virtues of their Tensor ASIC.

I have no doubt Google is already well on their way to a 14 or 16nm FF next-gen TPU

design and it's about to come to market.

Their 28nm TPU is already ahead on an obsolete node, it does not take much to imagine how

far ahead they will be when a new & improved design is fabricated on a current node.

How will NVIDIA be able to compete in future AI markets against ASICs which are orders

of magnitude more efficient?

Likewise, AMD is certainly the small fry in this battle, how can they compete with Vega?

Well, not all AI research or networks use Tensor operations.

Standard INT8 & FP16 throughput will remain useful, and for these uses, Volta & Vega can

compete in this market alongside Google.

Vega with up to 50 TeraOps INT8 and 25 TeraFlops FP16, at 225W can be very compelling for the

many open source ecosystems in this market.

Volta is even more compelling as it offers datacenters the ability to run Tensor ops

or standard ops, all in one package, supported by the CUDA ecosystem.

While the focus is on AI market opportunities, the traditional High Performance Computing

market is still rapidly growing, and here FP16, FP32 and FP64 performance is key.

For these metrics, Vega 10 and the 2018 Vega 20 compares very well against Volta GV100,

factoring in it's smaller die size and lower power.

Importantly, AMD can have a dual Vega accelerator, with very high performance in HPC where multi-GPU

is well leveraged.

Certainly AMD is not lacking in competitive HPC GPU accelerators moving forward.

Ofcourse, success in HPC depends on both hardware & software and in the software side, AMD has

come a long way, with their recent HPC software stack released and made open source, allowing

easy porting of CUDA to OpenCL.

For the HPC battle, AMD faces an uphill fight, but look at it this way, with Vega, AMD has

a viable challenger in HPC hardware, at a time where they also have a viable software

stack.

When they are rock bottom for this market, the only way is up.

Moving back to Volta, the other major changes that it brings, such as it's improved hardware

scheduler for thread scheduling & improved virtualization, unified L1 datashare, and

reduced instruction latencies are all very important for HPC.

Ofcourse all of this HPC focus is interesting, but as viewers, I am sure you would be wondering

what Volta can do for you as gamers.

The following will be speculation, so I could be wrong, and I invite you all to openly discuss

and contribute your own thoughts about these upcoming GPUs.

While it's not concrete, we do have some historic precedent to guide us.

Consumer Volta would likely be a stripped down GV100, re-arranged to maximize perf/w

for graphics.

Volta on paper look to offer a 40% performance per watt gain over Pascal, and NVIDIA claims

it's both due to architecture and node improvements.

Volta is built on TSMC's 12nm FFN, a customized 16nm FF node specifically for NVIDIA.

TSMC advertises density & power improvements for this particular process, with the gains

big enough to warrant a half node leap in naming it 12nm.

Interestingly, when we examine transistor counts for Pascal GP100 and Volta GV100, compared

to their die sizes, there has been no density improvements.

What this tells me is NVIDIA has chosen to sacrifice the density gains of 12nm FF to

maximize power efficiency.

Basically, less dense transistors suffers lower current leakage and so they are more

power efficient at high clockspeeds.

In simple terms, NVIDIA had to blow up their die space to the max of production capability

to fit the 300W power limits for GV100.

As such, I do not believe the bulk of the efficiency gains are from architecture changes,

rather, the major gains come from trading die area for power efficiency.

However, for the consumer Volta, none of this matters.

Why?

Because Pascal GP104 and 102 are still quite small for their market position.

There's headroom here for die space to grow with Volta, to maintain a similar power target

while increasing performance on 12nm FF.

GV102 for example, could be ~600mm2, packing 5,376 Cuda Cores in 6 Graphics Processing

Clusters.

This chip could be launching in Q1 of 2018 as a new Titan X Volta, slightly cut down

with 35% more performance than the current Titan Xp.

Meanwhile, GV104 could be ~420mm2, with 3,584 Cuda Cores in 4 Graphics Processing Clusters

and potentially launching later this year as a GTX 2080.

I fully expect this next-gen Volta mid-range GV104 to be 5-10% faster than the current

high-end Titan Xp.

Vega is targeted against the Pascal 1080Ti and if it somehow manages to beat it, assuming

perfect execution from AMD, it will have to battle against NV's next-gen Volta not long

after.

The problem AMD will face is GV104 achieves it's stellar performance with a small 256

bit bus using GDDR6, making it a low-cost card to produce.

Vega meanwhile is larger, and uses more expensive HBM2, this means AMD is not in a position

to fight this battle based on low prices.

The flagship Vega must deliver exceptional performance, surpassing Titan Xp or it will

truly be dead on arrival for the gaming market.

From the roadmaps we have available, in 2018, NVIDIA will have their full Volta stack, with

GV102 cementing the performance crown throughout the year.

It's something AMD has no answer for until their new multi-chip architecture, Navi, is

ready and current AMD roadmaps suggest it will not come to market until early 2019.

Basically in 2018, NVIDIA will once again have the entire high-end segment without competition,

as AMD's Vega 10 and 11 gets relegated to fight against the small mid-range GV104 and

tiny mainstream GV106.

Herein lies the major difference between AMD competing against Intel on CPUs, and AMD trying

to compete against NVIDIA with GPUs.

NVIDIA is a brilliantly led corporation, their CEO has unyielding long-term vision and the

company has a long record of excellent execution.

The major difference in ethos is obvious for all to see.

When Intel is ahead, they stagnate and rest on their laurels, content with minor iterations.

This lax management from Intel has allowed AMD the chance to strike back with Zen.

NVIDIA however, are relentless in their innovation.

Nobody expected a 815mm2 Volta from NVIDIA.

It's pure arrogance, yields be damned, at NVIDIA they push on ahead and leave their

competitors in the dust.

In many ways, Volta is the arrogance & vision of their longtime CEO, Jensen Huang, manifest

in silicon.

If anyone at AMD is watching this, the truth of the situation is this: to be competitive

against such a relentess competitor, you go big or you go home.

Saying this, I do understand the problem AMD faces, they do not want to risk such a large

chip as low yields do impact AMD more due to lacking high margin HPC marketshare.

But this thinking and the self imposed limitation is artificial, it no longer matters.

The recent successes from NVIDIA should be proof that the PC gaming market is stronger

than ever, especially at the high-end.

The early PC gamer generation is now mature with high disposable incomes.

This play-it-safe focus on performance per dollar is not the road to success against

NVIDIA who have shown if you consistently build the fastest GPUs, PC gamers will come

with their wallets ready.

It's clear that AMD has fallen behind NVIDIA, an entire year of no competition beyond the

$250 market, and with Volta on the horizon, the outlook for 2018 is bleak.

But there is light at the end of this tunnel.

Navi is designed to be a scalable multi-chip architecture, a collection of small GPUs on

an interposer which presents as one large chip to graphics APIs.

Navi solves AMD's biggest problem, they no longer have to worry about cost benefits and

margins of going with a large GPU to compete.

Navi however, is for another day.

For the next month, all eyes will be on Vega, let's hope the Radeon Technology Group can

execute a smooth launch.

For competition & gamers sake, Vega needs to surpass expectations to stand a chance

against NVIDIA's looming Volta attack.

Hopefully this video has stimulated your thoughts & expectations on these upcoming GPUs from

both AMD & NVIDIA.

Thank you for watching and see you all next time.

SCP-1602 A Shower Curtain | Object class Safe | Humanoid/Extradimensional/Transfiguration SCP - Duration: 13:52.

SCP-1602 "A Shower Curtain" Object Class: Safe

Item #: SCP-1602

Object Class: Safe

Special Containment Procedures: As it only exhibits anomalous qualities when spread out,

SCP-1602 must remain folded a minimum of 5 times when not undergoing testing.

When SCP-1602 is removed from its container to undergo testing or cleaning, no fewer than

three personnel are to be in a room with it at any given time.

It is currently kept at Storage Site-49 inside a standard containment locker.

Researchers seeking to conduct additional tests involving SCP-1602 must have written

approval from a Level-3 staff member before removing the item from containment.

Instances of SCP-1602-B are to be terminated by security personnel after research staff

has made sufficient notes regarding its behavior.

All remains are to be preserved and placed in storage.

Description: SCP-1602 is a plastic shower curtain patterned with stylized sea turtles.

When it is spread and placed in a room with a single human subject, SCP-1602 will enter

its active state.

After activation, an extradimensional space containing SCP-1602-A will be generated behind

SCP-1602.

This phenomenon will still occur even when SCP-1602 is placed against a wall or other

solid object.

5 to 30 minutes after activation, a faint light will appear roughly 3m behind SCP-1602,

casting a silhouette of SCP-1602-A on the back of the curtain.

SCP-1602-A will remain stationary for a brief period before drawing back SCP-1602 and approaching

the subject.

Pre-test counseling sessions conducted with D-Class subjects have shown that instances

of SCP-1602-A take on forms that are representative of the subject's psychological insecurities

(see Experiment Log).

If an additional party enters the room during this process, SCP-1602-A and any traces of

its existence will instantly vanish and SCP-1602 will reenter its dormant state.

If left unimpeded, SCP-1602-A will restrain the subject and forcibly pull them behind

SCP-1602.

Instances of SCP-1602-A have consistently proven capable of outrunning, overpowering,

and subduing subjects through nonlethal means.

Once the subject has been taken behind SCP-1602, SCP-1602-A will return SCP-1602 to its spread

position.

SCP-1602 will then reenter its dormant state, resulting in the disappearance of SCP-1602-A

and the captured subject.

In roughly 10% of tests conducted with D-Class personnel, the captured subject reemerged

from behind SCP-1602 unharmed and with no memory of their abduction.

In the remaining tests, SCP-1602 spontaneously reactivated 10 to 60 minutes after the subject's

disappearance and an instance of SCP-1602-B was generated.

SCP-1602-B appears identical to the most recent version of SCP-1602-A; however, they will

not disappear when viewed by a person other than the subject.

SCP-1602-B can be easily terminated with a standard firearm, even when SCP-1602-B possesses

no visible means of animation.

SCP-1602 was retrieved on 13/08/1988 from a hotel in ████████, South

Dakota.

During the initial containment mission, Foundation field agents discovered an instance of SCP-1602-B

inside a hotel room and presumed it to be an independant anomaly.

The instance of SCP-1602-B was designated SCP-████ and the mission was filed

as a success.

When Foundation intelligence intercepted a second report of a "monster" at the same hotel,

a more thorough examination of the building was initiated and SCP-1602 was contained.

Experiment Log:

Test 1602-5 Subject: D-1602-5, a Caucasian male, age 20.

During conversations with on-site counsellor Dr. ██████, subject confessed

that he that had coerced his girlfriend into having an abortion.

Subject expressed profound feelings of regret surrounding this event.

Procedure: SCP-1602 hung on a plastic shower rod suspended from the ceiling in the middle

of the test chamber.

Subject was instructed walk around SCP-1602 and view the other side once it entered an

active state.

Results: SCP-1602 entered an active state after approximately 5 minutes, consistent

with activation time in previous tests.

The subject noticed a faint light emanating from behind SCP-1602 and walked around to

view the other side.

Subject reported that upon viewing the other side, SCP-1602 apparently reentered its dormant

state: the light vanished and was no longer visible from either side of SCP-1602.

No other anomalous activity reported.

Test 1602-6 Subject: D-1602-5, same as previous test.

Procedure: SCP-1602 hung on a plastic shower rod suspended from the ceiling in the middle

of the test chamber.

Subject was instructed to stand in place and observe only one side of SCP-1602.

Results: SCP-1602 again entered an active state after approximately 5 minutes.

10 minutes and 23 seconds into the test, a small, undefined silhouette appeared at the

base of the curtain.

An instance of SCP-1602-A (SCP-1602-A6) emerged precisely 3 minutes later, taking the form

of a newly born child covered in vernix caseosa and blood.

SCP-1602-A6 crawled out from beneath the curtain in the direction of the subject.

Upon observing SCP-1602-A6, the subject screamed and stumbled backward, losing balance and

collapsing on the floor.

Several hundred additional instances of SCP-1602-A6 continued to emerge; many of these were identical

to the original instance, although 22% of duplicates still bore umbilical cords.

Acting as a group, SCP-1602-A6 converged on the subject.

Subject fought back but was overpowered by SCP-1602-A6 and was subsequently dragged behind

the curtain, followed by all remaining SCP-1602-A6.

A single instance of SCP-1602-B6 emerged after 15 minutes.

Autopsy confirmed that its anatomy was consistent with that of a typical infant, although its

internal organs were found filled with live maggots.

Samples of the maggots were preserved and placed in storage.

Additional: Any traces of vernix caseosa and blood left on the floor by SCP-1602-A6 ceased

to exist the moment Research staff entered the room.

Note: The presence of multiple instances of SCP-1602-A at one time suggests that SCP-1602-A

are entities generated each time SCP-1602 enters an active state, rather than a single

entity that assumes different forms, as had been previously theorized.

- Dr. Lindquist

Test 1602-7 Subject: D-1602-6, a Hispanic female, age

33.

Subject had a history of bulimia and self-image disorders.

Procedure: SCP-1602 placed in a spread position against the wall of the test chamber with

a mild adhesive.

Results: Subject exhibited high levels of anxiety and panic upon SCP-1602 entering its

active state, repeating the phrase, "I can't do this."

This pattern of behavior continued until SCP-1602-A7 appeared behind SCP-1602, at which point subject

began banging on the wall opposite to SCP-1602 while shouting incoherently.

SCP-1602-A7 pulled back the curtain, revealing a cavity in the wall that had not previously

existed.

SCP-1602-A7 was identical to the subject in height and race, but appeared to possess no

muscular tissue whatsoever, with skin stretched directly over its bones and ligaments.

Lack of musculature notwithstanding, SCP-1602-A7 still possessed a high level of mobility and

strength, grabbing the subject by the ankles and pulling the subject behind the curtain.

An instance of SCP-1602-B5 emerged within 5 minutes of the subject's disappearance.

SCP-1602-B5 was observed to claw at its own body, its jaw fully extended but making no

vocalizations.

Researchers called for termination after 4 minutes of observation.

Autopsy deemed unnecessary as SCP-1602-B5 had peeled back most of its own skin, confirming

its lack of muscle tissue.

Retrieval of SCP-1602 showed the wall to be in the same condition as it had been at the

beginning of the test.

Test 1602-8 Subject: D-1602-7, a Caucasian male, age 58.

Subject had been a high-ranking employee of ████████, a Fortune 500 company,

prior to incarceration.

Dr. ██████, who provided counseling for the subject in the weeks prior to testing,

noted that the subject expressed significant frustration over the fact that his dedication

to his work had led to his estrangement with his children and ex-wife.

Procedure: SCP-1602 placed on the floor in a spread position.

Results: SCP-1602's horizontal orientation did not appear to alter its effects, activating

within the standard timeframe.

SCP-1602-A8 emerged from beneath it, climbing from a perfectly round hole in the floor that

had not existed prior to SCP-1602's activation.

SCP-1602-A8 took the form of a clown in a loose, polka-dotted suit.

While its body seemed to be that of a natural human, its head was disproportionally large

and made from what appeared to be papier-mâché, with areas of the face cut out where its eyes

would typically be located.

A reflective substance (later confirmed to be standard confetti) poured continuously

from these orifices for the entire duration of the test.

This test marks the first time an instance of SCP-1602-A has made vocalizations, despite

its lack of visible means of articulation.

SCP-1602-A8 approached the subject very slowly, repeatedly expressing a desire to 'play' and

encouraging the subject to 'loosen up and live a little'.

Subject attempted to engage SCP-1602-A8 in conversation, making numerous inquiries about

its nature, albeit with a significant amount of profanity.

34 minutes after the subject's capture, SCP-1602-B8 was generated and proceeded to stumble around

the room in a state of extreme distress.

Like SCP-1602-A8, it made numerous vocalizations, though most of its statements were requests

to see Dr. Lindquist and questions regarding its own nature.

The following is the subsequent exchange between SCP-1602-B8 and Dr. Lindquist.

<Begin Log>

Dr. Lindquist: We'll start by confirming your identity.

What is your name?

SCP-1602-B8: (Confetti still pouring from its facial orifices) [REDACTED].

Dr. Lindquist: What are the names of your children?

SCP-1602-B8: [REDACTED].

What's happened to me?

Dr. Lindquist: Please remain calm and answer the questions.

Do you have any pets?

SCP-1602-B8: I have a Great Dane named Dorothy.

Please, Doctor, I need help, I'm blind and—

Dr. Lindquist: What did you see after you were taken behind the curtain?

SCP-1602-B8: I didn't see anything.

What's happened to my face?

Why am I blind?

What did that [EXPLETIVE REDACTED] clown do to me?

Dr. Lindquist: That's what we're trying to figure out.

We want to help you, but you need to answer our questions.

Did SCP-1602-A8 say anything to you after—

SCP-1602-B8: You let that thing do this to me!

For the love of God, Doctor, what's it done to me?

Why can't I see anything?

Why is everything so cold?

Why does my head feel so…

(SCP-1602-B8 raises its hands to its face and makes vocalizations similar to weeping.)

Dr. Lindquist: Please try to remain calm.

I only have a few more questions—

SCP-1602-B8: (Still weeping) Nothing's changed.

Nothing's changed.

<End Log>

Closing Statement: SCP-1602-B8 refused to respond to any further questioning and was

terminated shortly after interview.

It is unknown if D-1602-8 was physically transmuted into SCP-1602-B8, if the subject's consciousness

was transferred, or if SCP-1602-B8 was impersonating the subject.

Much of the confetti produced by SCP-1602-B8 was incinerated, with a small amount stored

in a small plastic container and placed in storage.

Test 1602-18 Subject: D-1602-21, an African American male,

age 46.

Subject was uncooperative in counseling sessions, but was found to have a history of impoverishment.

Procedure: Subject given a standard firearm and placed in a bulletproof testing chamber

with SCP-1602.

Results: SCP-1602-A took the form of an elderly, emaciated black male dressed in heavily damaged

winter clothing.

The subject fired several rounds of ammunition which had no visible effect on SCP-1602-A.

The subject was apprehended, as expected.

No activity was detected from SCP-1602 for two hours, after which the subject reemerged,

apparently unharmed and visibly damp.

When interviewed, the subject claimed that he had not been abducted, and had in fact

simply taken a shower, describing the experience as "pleasant" and "cleansing".

Testing is ongoing.

When 'psycho' automation left this pilot powerless - Duration: 5:07.

On the seventh of October 2008,

a Qantas plane flying from Singapore to Perth

declared a MAYDAY to air traffic control.

When it made an emergency landing

at a small airport on the West Australian coast,

it had onboard

more than a hundred injured passengers and crew.

They had broken bones, lacerations and spinal injuries,

while compartment doors had been ripped from hinges

and passengers' belongings were strewn throughout the cabin.

Less than an hour earlier,

passengers with and without their seatbelts on

had impacted the cabin ceiling

when the plane had twice dropped several hundred feet

without warning.

<b>"A sudden loss of height,</b>

<b>the plane being thrown around in the air</b>

<b>and the screams of those around you."</b>

For Qantas -

which boasted an unparalleled flight safety record -

this was completely out of the ordinary.

The media was quick to blame the accident

on clear-air turbulence,

but what really happened to the plane

was something far more disturbing.

QF72 was an Airbus A330 plane

that was just one hour and a half from its destination

when all hell broke loose.

The flight's captain, Kevin Sullivan,

was a former US Navy fighter pilot -

at the time of the accident he had

over 13 thousand flying hours in his logbook.

When I returned to the flight deck,

I knew that we were flying at 37 000 feet.

The body angle was 2 degrees above the horizon.

The flight control computers, however,

thought we were flying at 50 degrees body angle

and overspeeding at the same time.

Now we know that's pretty impossible.

It says that's where we're flying -

we're flying like this -

"I must protect the airplane".

So it pitched the nose down.

It went from plus 2 to minus 8.4

in less than a second.

Look what the tail's doing.

If you're back there,

you're going to feel the force.

What Captain Sullivan was coming up against

was a change in how airplanes have been made

in the last thirty years.

Traditional jumbo jets -

such as the Boeing 747 -

are controlled by the pilot

through mechanical connections to the hydraulic systems

which move the flight control surfaces -

that is, the rudder,

the elevator and the ailerons.

But the Airbus A330

is what's known as a fly-by-wire system,

where there is no such manual control.

Instead, the pilot's controls make requests of a computer,

which sends electronic signals

in order to move the flight controls.

Fly-by-wire planes are lighter and more fuel-efficient.

They're also capable of executing

faster and more precise movements than humans,

and they reduce the chance of pilot error

by preventing the plane from exceeding certain limits,

known as the flight envelope.

It is the flight computer's protection modes

that prevent the aircraft from exceeding the flight envelope -

and when they became active,

they blocked Captain Sullivan's attempts

to stop the computer's command.

It's like 2001: A Space Odyssey.

"HAL, open the pod bay doors."

"I'm sorry Dave, I can't let you do that."

I'm saying, "Don't push the airplane down".

I'm pulling back on the stick.

The computers are saying, "I'm sorry Kev,

I'm not going to let you do that".

But the fact is that fly-by-wire planes

have actually made air travel much safer.

In the past decade,

the number of commercial passenger flights has surged,

while the number of fatalities in plane accidents has fallen.

But in the case of flight QF72,

the manufacturer's design prevented the pilot

from overriding the computer's control.

In the A330 course,

you're taught you must interact:

you can interact with the plane.

It's great and when it works, it's great.

But when it doesn't work,

you're in the dark.

An investigation by the Australian Transport Safety Bureau

found that one air data computer

was sending incorrect body-angle and speed information

to the three primary flight control computers -

which reacted to the data

by forcing the plane to pitch down.

The flight maintenance log revealed

that 10 simultaneous faults

had occurred during the accident -

and most of these had been hidden from the pilots.

The hierarchy of this particular airplane

is that the computer is number one

and the pilot is number two.

If they, for example, decide that

you're overspeeding and stalling

and they're going to protect you -

there's no right to veto that.

But for Captain Sullivan,

there is a bigger question left to be answered

and it's not just about the computers onboard flight QF72.

As we start to trust computers with delivering our goods

and even driving our cars -

just what level of control

should we keep for ourselves?

I've never even -

in all the extreme flying I did in the military -

did I ever say to myself:

"Hey, you're in trouble".

Those are very profound words for a pilot

to admit to himself, as I did,

and saying, "Yeah, I'm in a knifefight with this airplane

and only one person is going to win

or one computer is going to win".
