Intel To Ship Xeon Phi For "Exascale" Computing This Year

MojoKid writes "At the International Supercomputing Conference today, Intel announced that Knights corner, the company's first commercial Many Integrated Core product will ship commercially in 2012. The descendent of the processor formerly known as Larrabee also gets a new brand name — Xeon Phi. The idea behind Intel's new push is that the highly efficient Xeon E5 architecture (eight-core, 32nm Sandy Bridge) fuels the basic x86 cluster, while the Many Integrated Core CPUs that grew out of the failed Larrabee GPU offer unparalleled performance scaling and break new ground. The challenges Intel is trying to surmount are considerable. We've successfully pushed from teraflops to petaflops, but exaflops (or exascale computing) currently demands more processors and power than it's feasible to provide in the next 5-7 years. Intel's MIC is targeted at hammering away at that barrier and create new opportunities for supercomputing deployments."

I'm not sure what the "news" is here - it's larrabee with a die shrink. Doesn't intel do this with their tick-tock strategy on ALL their architectures?

Re:Larrabee (redux)

[raftpeople]

Yes, but this is the first time they've applied the "tick-tock" strategy without actually shipping the product.

Re:Larrabee (redux)

[Auroch]

Yes, but this is the first time they've applied the "tick-tock" strategy without actually shipping the product.

I don't know. I can't cite a single example, but I doubt this is the case. It's probably more like that it's the first time they've applied the "tick-tock" strategy without shipping the product after making a big deal about the un-shipped product.

Re:Larrabee (redux)

[gman003]

It's more of "they're actually RELEASING it".

Larrabee, essentially, was never released. It was demonstrated, and a few were even given/lent to researchers for testing, but it was never used in an actual product.

That's why it's *still* known only by its codename. You don't need a real name until you're actually planning to put it on shelves.

That's why it's "news". It's transitioning from a *fascinating* research project to a real, commercial product.

Re:Larrabee (redux)

[Nemyst]

There's a difference in terms of target. Larrabee was initially supposed to be Intel's first shot at being competitive in the GPU market. This reuses a lot of the tech, but it's more like having a bunch of Xeon processors in a PCI-E slot. It's general purpose, massively parallel computing power, which could make it a sweet spot for things like video transcoding or CGI (as GPU solutions tend to be fairly lossy).

The interesting thing about this is that it could basically transform any desktop computer with a modern motherboard into a mini-supercomputer. With two PCI-E slots you can get over 100 CPU cores, which is rather nice as it's all off-the-shelf hardware (well, aside from the probably ridiculously pricey Xeon Phi boards themselves).

Best HPC news for Linux EVER

[CajunArson]

For all of the anti-Intel FUD that is about to be unleashed because this thing doesn't play games: The MIC system is *LIGHT YEARS* ahead of any other device in this space when it comes to supporting Linux and open source. This thing is not just compatible with Linux... it actually runs a Linux kernel natively. Intel has already released an open source software stack, and while it will take some work there will eventually be full GCC support for the 512-bit SIMD instructions that give this thing its processing oomph.

Driver? THERE IS NO DRIVER.. Ok there is a rather simple driver that's already been submitted to the Linux kernel 100% open source for transferring data back and forth from the card, but it is about a trillion times simpler than the monstrosities that pass for GPU drivers. This is a *co-processor*, not some black-box video card that where you pass off code written in a quasi-standard format to be compiled (!) by a video-card driver.

This thing is already more open-source and Linux friendly than anything made by Nvidia or AMD (and no, dumping partially completed documentation 6 months after the card is released with no real support is *not* the same thing as *freaking running Linux on the board 100% open-source before the product even launches*).

If people on this site were rational they'd be setting off fireworks to celebrate this architecture, but because it doesn't have the name "ARM" or "AMD" on it they idiotically reject it as "closed source" for some reason....

What they don't talk about for supercomputing in this article is the interconnect. Because the X86 instruction sets are massive, it generally does not work very well. Piping that many large instructions scales poorly, hell it's hard to get 8 chips on a board let alone having an interconnect bundling 128 or so. This is the advantage that RISC has always had over architecture, and why every supercomputer up to date worth speaking of has used RISC over Intel X86.

I'm going to assume it's just a pipe dream until I see an interconnect that can operate over many CPUs on a X86 platform without choking itself to death. And hell, heavy duty computing requires Linux. I'm sure Balmer tried to work a deal though. Good job Intel!

Good lord, I can only imagine what a raytracer could do with that platform, or anything else for that fact. Need to run RAID5 but you don't have a RAID card? No problem, run the XOR calculations on your Phi. Want transparent FS compression and realtime de-duplication? Run that stuff on the Phi. The possibilities are nearly endless here because the card and software stack are totally open.

I disagree. Half of the top 10 current supercomputers at top500.org are x86 (some with GPGPU), 4 are IBM POWER, and 1 is SPARC64. Most of them are using Infiniband. Honestly, #4 is x86. Just add more computers and it'll be #1. That's basically how the current #1 got there. It's just a matter of how much money institutions are willing to spend to get there.

With all due respect, this seems more similar to barebones shader programming than to the usual issues running OpenGL which is why it's "about a trillion times simpler".

Assembler ~= shader programming ~= Xeon Phi programming
OpenGL ~= Java, C#, C++/Qt, C++/Gtk ~= nothing the stack you talk about does

From what I gather this chip essentially gives you SSE on steroids, it's an alternative to CUDA and OpenCL but nothing else a graphics card does. And while currently the Linux capability is just to get the chip up and running, it doesn't actually use the new instructions unless you write it in assembler:

The changes do not include support for Knights Corner vector instructions and related optimization improvements. GCC for Knights Corner is really only for building the kernel and related tools; it is not for building applications. Using GCC to build an application for Knights Corner will most often result in low performance code due its current inability to vectorize for the new Knights Corner vector instructions. Future changes to give full usage of Knights Corner vector instructions would require work on the GCC vectorizer to utilize those instructionsâ(TM) masking capabilities. This is something that requires a broader discussion in the GCC community than simply changing the code generator.

Re:Best HPC news for Linux EVER

[CajunArson]

Uh... so you just admitted that its possible to write assembler for the new SIMD instructions (which are already 100% publicly documented). And if you can write assembler... what else could you do? Maybe... incorporate the new instructions into GCC? It worked for the C programming language! Sure it would take work, but when ARM came out with NEON instructions they were in the exact same boat, and I haven't seen anyone insulting ARM about that. That is MIC's huge advantage in addition to having a very competitive hardware architecture.

You insult these new instructions as just being an expansion on SSE, but guess what: lots of software takes advantage of SSE and the changes required to use MIC would be *trivial* compared to trying to futz around with CUDA or AMD's flavor of OpenCL. Not to mention that if you are really married to OpenCL you could get it working on MIC with much less effort than trying to either write your own GPU driver or deal with the inconsistencies in Nvidia and AMD's offerings.

Lessee... please name one graphics card where you can emit code directly from GCC to work on the GPU hardware... oh wait, you can't because the GPUs are completely non-standardized and require god-awful translation layers.

Re:Best HPC news for Linux EVER

Sorry, but you can't count GPU based systems as X86. You are using a RISC based chip as the workhorse in the cluster, with exceptional math co-processing of course. The X86 chips act as a bridge, which is what they can do best in my opinion.

Classic slashdot -- post a bunch of ignorance and pretend that it's meaningful.

Code density: reality is the opposite of what you claim. x86 is relatively dense, and RISC ISAs tend to be less dense. This is precisely because variable length instruction sets like x86 tend to pack more tightly than fixed length ISAs like a classic RISC. Instruction decode complexity was the nut the original RISC designers in the 1980s were trying to crack, and they were willing to accept reduced density to simplify it. (Note that what was a good tradeoff in the 1980s is not necessarily a good tradeoff today!)

Interconnect: here you are just plain disconnected from reality. Any supercomputer which uses even a small fraction of its interconnect bandwidth routinely moving code around is a supercomputer running code written by the malicious or incompetent. Code should be distributed to local memories in each node and cached by the local processors. Except for startup, instruction fetches should never need to traverse interconnect. This is true regardless of instruction set.

8 chips on a board: actually, Intel's standard glueless interconnect in high end Xeons already supports 8 sockets. And if you knew jack about large x86 systems you'd know there are also vendors adding their own fabric glue on top to scale up further. Try 256 sockets on for size:

http://www.sgi.com/products/servers/uv/models.html

(And this is by no means the largest thing possible.)

And hell, heavy duty computing requires Linux. I'm sure Balmer tried to work a deal though. Good job Intel!

Yet more classic slashdot: insert mindless Microsoft bashing and pro-Linux rah-rah-rah where it doesn't even make sense because Intel is bloody well using Linux on these things!.

Assembler ~= shader programming ~= Xeon Phi programming

This is a false equivalence. Xeon Phi programming is relatively standard SIMD assembly programming, except easier than average because they did an awesome job designing the ISA (seriously, go back and look up the Dr. Dobbs article on the ISA written back when they were still going to try to productize it as a consumer GPU, it may have failed but it didn't fail because the vector ISA was a poor design). Shader programming tends to be a lot more involved, esoteric, and complex. You'll bump into a lot more limitations, dataflow problems, control flow inflexibility, and so forth.

Future changes to give full usage of Knights Corner vector instructions would require work on the GCC vectorizer to utilize those instructionsâ(TM) masking capabilities. This is something that requires a broader discussion in the GCC community than simply changing the code generator.

Those masking capabilities should make it a lot easier to write a vectorizing compiler than traditional vector ISAs. There will be far fewer cases where an optimal compiler should suppress vectorization. When you're targeting something like SSE, which is much less regular and flexible and has a lot more control flow gotchas, it's a lot harder for the compiler to make good decisions about what should and should not be vectorized. So if anything, the modifications will be along the lines of "simplify this for this case, because all these old complexities are now irrelevant".

Besides, what exactly is your objection here, that new ideas require effort to implement? That's silly. If they're genuinely better ideas, we'll be better off once that's been done.

x86 instruction set has nothing to do with how many chips you can get on a die. I have no idea why you keep talking about interconnects and x86 like they're related. x86 sits between the L1 cache and the core and has nothing to do with anything else.

Isn't Larrabee a graphic chip ?

[Taco Cowboy]

Am I missing something?

Why in the world Intel wants to resurrect a many-cored graphic chip that performed far worse than what Nvidia or ATi are offering?

Re:Isn't Larrabee a graphic chip ?

[0123456]

AFAIR, Larrabee was a ton of cut-down x86 cores on a graphics chip. So it could be far more useful for massively parallel computing.

Re:Isn't Larrabee a graphic chip ?

[Anonymous Coward]

Larrabee never really was about graphics, that's only one use. It works like a normal cpu, runs x86 and memory access is not gpu-like retarded. There are 512-bit SIMD instructions to help parallel processing, which is good if you need to render pixels, but sandy/ivy-bridge is closing the gap on it with 256-bit AVX. When haswell comes around (AVX2) with possibly even more cores I don't really see why anyone would buy it, unless it bumps the core count to like 32/64 and adds a lot of cache.

Re:Isn't Larrabee a graphic chip ?

[gman003]

It was, sort of.

Modern GPUs are essentially thousands of very simple, low-speed cores. Think of a thousand 486s. They use driver software to make it do the graphics calculations, because that means they can be more flexible. There are no fixed-function pipelines anymore - it's all software, either in the drivers, or in the customizable shaders.

Intel's plan was to make a GPU that has a few dozen (32 or so) more complex cores, that were x86 compatible. They added some specialized extra-wide SIMD stuff and some fast-blitting texture units, but it was still x86 compatible. And they had some very impressive drivers to make it function as a "graphics card" - they even demonstrated real-time raytracing in 2009, something nVidia only demonstrated their cards doing this year (and Intel did it in an actual game, not a tech demo).

However, that flexibility made it a bit underwhelming at the things most games actually do, so it really couldn't compete in that marketplace, at least not at the prices they expected to need to be profitable. But that highly-flexible but also highly-parallel architecture seems perfectly suited to supercomputing.

I don't really see why anyone would buy it, unless it bumps the core count to like 32/64 and adds a lot of cache.

Knights corner was originally quoted as being ~48 cores, each core could do 4 way hyperthreading, and each thread could process 16 floats instead of your usual 8 (with AVX). That was all backed up by 2Gb DDR5 memory. The hardware prototypes they've shown, certainly seem to be in that ball park, so I don't imagine the specs have got any worse over the last year or so. I'd buy one, for no other reason than it looks like it would be quite an enjoyable platform to target.

Re:Isn't Larrabee a graphic chip ?

Looking over the comments so far... I want one! Not because I play a lot of games, but because I do some video editing, and even though nVidia's VDPAU is good, it's not as good as having quite a few more cores chewing away at some HD footage. Where do I sign up?

Uh... what??!

Cell: each stream processor core has access to its own local scratch memory, and cannot directly access any other core's memory, or even (IIRC) the main system memory (DRAM). There are DMA engines to copy data around and you must use them to explicitly manage dataflow. If the code running on the stream processors requires random walks through a large data structure, you will know real pain.

Larrabee/Knights Corner: each processor core is a full fledged x86, with its own caches. However, all caches in the chip are coherent, with standard x86 SMP semantics including memory ordering. Write anything to any address, and all other cores can see it automatically. The only oddity is that the Larrabee address space is separate from the host computer, but the intent is that you just run an OS instance on Larrabee (Intel uses Linux) and treat it as a computer which happens to be packaged as a PCIe card.

One of these things is possibly even worse than GPU insanity. The other is just the standard x86 SMP memory model.

And what I get on a laptop/desktop is staggering compared to how much energy I use doing trivial things like lighting, cooking, dishwasher, washing machine and so on and I don't even generally use electric for heating/cooling. And if you count just the actual computing on the CPU/GPU and ignore the display etc. it's even more extreme.

I don't know about the Ivy chips, but some of the Atoms boast power usage as good as an equal-performance ARM... for the processor.

About six months ago, I was overexerting myself trying to get rid of a terrible virus on a client's PC (I own a PC repair shop and have been fixing computers for over 10 years). Given my level of expertise, I thought I'd be able to get rid of it fairly quickly and without hassle, but as was made evident by my colossal failure, I was horribly, horribly wrong.

I couldn't remove the virus no matter what method I used. I tried all the latest anti-virus software and all the usual tricks, but it was all in vain. Failure after failure, my life was slowly being sucked away as I spent more and more of my time trying to get rid of this otherworldly virus.

Frustrated and stressed by my own failure, I began distancing myself from my wife and children. After a few days, I began verbally abusing them, and it eventually escalated into physical abuse. I was slowly losing what remaining sanity I had left. If this had continued for much longer, it is highly probable that I would have committed suicide. A mere shell of what I once was, I barricaded myself in my bedroom and cried myself to sleep for days on end.

That's when it happened: I found MyCleanPC! I installed MyCleanPC right on the client's PC, ran a scan, and it immediately got rid of all the viruses without a single problem. MyCleanPC accomplished in record time what I was unable to accomplish after a full week. Wow! Such a thing!

MyCleanPC is outstanding! My client's computer is running faster than ever! I highly recommend you install MyCleanPC right this minuteness, run a scan, and then boost your PC speed in record time! MyCleanPC came through with flying colours where no one else could!

My client's response? "MyCleanPC totally cleaned up my system, and increased my speed!" All the PC repair professionals are using MyCleanPC to solve all of their problems. This should be reason enough for you to switch to MyCleanPC! It'll speed up your computer, rid it of all viruses, and you'll be able to work productively again! Wow!

Even if you're not having any obvious computer problems, you could still be in danger. That's why I very highly recommend that you still use MyCleanPC. After all, it will boost your PC & internet speed to levels you never would think are possible!

MyCleanPC: For a Cleaner, Safer PC.

A few weeks ago, I foolishly ran a strange executable file that one of my acquaintances sent me by email. As someone who doesn't know much about computers, at the time, I thought nothing of it. "Why would my acquaintance want to hurt me?" Following this line of thought, I ran the file without question.

How naive I was. Despite having what was supposedly the best anti-virus software out right then, a virus took over my computer and held it hostage. It was pretending to be a warning from Windows telling me to buy some strange anti-virus software I'd never heard of from a company I'd never heard of to remove the virus.

This immediately set alarm bells off in my head. "How could this happen? My anti-virus is supposed to be second to none!" Faced with this harsh reality, I decided to take it to a PC repair shop for repair. They gladly accepted the job, told me it'd be fixed in a few days, and sent me off with a smile.

About six months ago, I was overexerting myself trying to get rid of a terrible virus on a client's PC (I own a PC repair shop and have been fixing computers for over 10 years). Given my level of expertise, I thought I'd be able to get rid of it fairly quickly and without hassle, but as was made evident by my colossal failure, I was horribly, horribly wrong.

I couldn't remove the virus no matter what method I used. I tried all the latest anti-virus software and all the usual tricks, but it was all in vain. Failure after failure, my life was slowly being sucked away as I spent more and more of my time trying to get rid of this otherworldly virus.

Frustrated and stressed by my own failure, I began distancing myself from my wife and children. After a few days, I began verbally abusing them, and it eventually escalated into physical abuse. I was slowly losing what remaining sanity I had left. If this had continued for much longer, it is highly probable that I would have committed suicide. A mere shell of what I once was, I barricaded myself in my bedroom and cried myself to sleep for days on end.

That's when it happened: I found MyCleanPC! I installed MyCleanPC right on the client's PC, ran a scan, and it immediately got rid of all the viruses without a single problem. MyCleanPC accomplished in record time what I was unable to accomplish after a full week. Wow! Such a thing!

MyCleanPC is outstanding! My client's computer is running faster than ever! I highly recommend you install MyCleanPC right this minuteness, run a scan, and then boost your PC speed in record time! MyCleanPC came through with flying colours where no one else could!

My client's response? "MyCleanPC totally cleaned up my system, and increased my speed!" All the PC repair professionals are using MyCleanPC to solve all of their problems. This should be reason enough for you to switch to MyCleanPC! It'll speed up your computer, rid it of all viruses, and you'll be able to work productively again! Wow!

Even if you're not having any obvious computer problems, you could still be in danger. That's why I very highly recommend that you still use MyCleanPC. After all, it will boost your PC & internet speed to levels you never would think are possible!

A few weeks ago, I foolishly ran a strange executable file that one of my acquaintances sent me by email. As someone who doesn't know much about computers, at the time, I thought nothing of it. "Why would my acquaintance want to hurt me?" Following this line of thought, I ran the file without question.

How naive I was. Despite having what was supposedly the best anti-virus software out right then, a virus took over my computer and held it hostage. It was pretending to be a warning from Windows telling me to buy some strange anti-virus software I'd never heard of from a company I'd never heard of to remove the virus.

This immediately set alarm bells off in my head. "How could this happen? My anti-virus is supposed to be second to none!" Faced with this harsh reality, I decided to take it to a PC repair shop for repair. They gladly accepted the job, told me it'd be fixed in a few days, and sent me off with a smile.

Actually, I wouldn't be surpised if the original requester of this technology was a three letter agency needing absurd amounts of fast processing to decrypt lots and lots of data.

Re:you don't suppose...

I'm pretty sure the military has had access to very similar technology for a while. I recall reading an article several years ago that talked about 100+ core designs in an expansion slot.

Uh, no. No conspiracy thinking is necessary. Intel quite openly developed it with the intent of productizing it as a consumer GPU, and the original version of it has all sorts of features which were only necessary for that function (like some fixed function units dedicated to texture mapping, which they'd determined could not be efficiently implemented in software, unlike the rest of the 3D rasterization pipeline). It was basically trying to skate to where the puck would be. GPUs were trending to be more and more programmable, so why not go all the way and make the programmable elements simple x86 CPUs living in the same unified address space as the rest of the system?

That plan didn't work out so well. They had a few delays and by the time the original GPU iteration was ready for market, it was going to be uncompetitive with ATI and nVIDIA GPUs. That and generally tepid reaction convinced them to cancel the GPU idea (for now, it'll be interesting to see if it comes back eventually). But they still had a lot of interest from the HPC market, because their architecture offers similar peak compute throughput to GPGPU with a much simpler programming model, and far fewer ways to fall off of peak throughput. (GPGPU programming tends to require a lot of optimization to get the most out of a GPU, since the machine models for GPUs are so weird and unbalanced for general purpose code.)

skip the graphics - go to AI uses

[Anonymous Coward]

I looked at Larabee (wasnt that a Get Smart agent name??) long ago looking at its use for AI. But it never got out into the world.

The GPUs were too restricted by their warp/ weave parallelism and limited if-then and limited localized data made them inefficient for extreme random and irregular logic that alot of behavioral AI uses (we have plenty of graphics in games these days, its the AI thats on lamestreet.

Windows is the best

But the Microsoft guy that bought my staff lunch told us that Windows was the leader in High Performance Computing. And that Hyper-V will innovate a new paradigm shift in the world of clusters, data centers and HPC.
