SC11: A Review in Schwag

This is the less serious bit of review from SC’11, but there is fun to be had and a certain amount to be learned from the pile of schwag that comes back. The schwag pile is comparable to last year’s, but I was actively aimed toward useful or at least interesting junk this year, since I have > three cubic feet of this crap packed away now. Part of the point of this post is just to give credit (and links) to places that gave me cool stuff.

I find I actually use the various random bags I get, so I always end up with quite a few. Several were particularly nice: For the second year in a row, I would actually USE the conference bag (Back left corner) on it’s own, and I got another one of the ridiculously tough Tyan/Intel bags (far back, standing) which are handy for groceries and toting stuff around campus. Indiana University had a nifty little sling bag that I could contrive uses for (next to conference bag), and the giant blue CSC bag can consolidate a remarkably large pile of crap.

With regard to apparel, Silicon Mechanics again had the nice florescent green on black logo tee that I wear all the time, although this year’s has some text on the back that makes it a little less cool. We hung out for a while talking to the Pogo Linux folks and were handed a pile of their shirts (logo on front, gold circle around Tux on back, back visible in picture), which are pretty nice. The Adaptive Computing/MOAB “Lifes a Batch” shirt is clever in the same way the Platform Computing “Whatever” shirt from a few years ago – I don’t know that it will get worn much, but it’s a memorable marketing effort (and, by the way, Moab has become really impressive – it can do PVM type tricks that PVM can’t, and look good doing it). NIMS (I’m slightly embarrassed to say I don’t remember which relevant organization with that acronym it was) had nice Beanies which may see some use this winter. I have some fuschia compact umbrellas from the conference daily giveaway (I think IBM payed for/logo’d them) to be given as gifts – we brought back one or two each… plus a box of a dozen after they stuck the remainders out.

Going through the gallery of other neat stuff in order of a appearance:

  • Huge props to Samtec. I don’t recall seeing them at SC in previous years, but as an interconnect hardware vendor, it’s an entirely reasonable place for them to be. In addition to the fairly nice hat/pen/screwdriver schwag items and interesting to chat with booth staff, they were giving out trays of sample parts. I picked up the “Sample Solution” and “Rugged Power” kits, since those are the kinds of connector I use most, but the adviser picked up a full set to keep on file for helping students doing projects pick parts. Looking through them I wish I had picked up one of the R/F component boxes, because it had a gorgeous assortment of $Random_antenna_connector to SMC pigtails in it. I think I’ll be preferentially ordering/recommending connectors from them for a while.
  • Penguin Computing was dispensing nice umbrellas in addition to their standard “Sit through our talk for a 6″ Stuffed penguin” routine. I talked management tools with a rep for a while, but didn’t attend the talk this year.
  • Several places had nice small papergoods. I consume little notebooks and packs of post-its and tape flags pretty regularly, and can’t remember the last time I paid for them.
  • Isilon had a nice little screwdriver pod thing. There can never be enough multitools.
  • HP was handing out a … dorky green thing. It’s cute, and charming, and its belly is a lint-free screen cleaner, but I can’t figure out what the hell it is (alligator?). I think the confusing object is representative of their confusing business decisions of late – they had a carnival tricks theme going in their booth which also fits circus grade management.
  • AMAX and Extreme Networks gave me flash drives, in addition to the proceedings drive (which is 2Gb and looks like a Kingston like the last two years, but the USBID says knockoff). Apparenlty I missed some even nicer flash drives from other places that group mates found. Flash drives are always useful and appreciated.
  • The NNSA ASC booth was shoveling Flexible USB Lights out of their booth the last day, and I took a couple. I’m not sure what I’d use them for, but they appear to be identical to this $10 thing at Thinkgeek, so there’s that.
  • The Arctic Region Supercomputing Center booth was not very well staffed, but they had their usual reusable chemical hand warmers, which is a great gimmick.

The “trick-or-treating for grownups” vibe of going schwagging on the floor is a bizarre joy of supercomputing, and, in addition to the standard “memorable schwag makes you memorable” marketing function, actually provides an important mechanism for striking up conversations and encouraging attendees to make good coverage of the exhibit floor. I have a not inconsiderable list of organizations who have bought good vibes with a few cent trinket, and I am the sort of person who gets solicited for tech and academia advice, so the trinkets are doing their job.

SC’11 Lessons

I learned some really interesting things at SC this year, and now that I’ve had a day to process, I want to share. Many of these observations come from first or second hand conversations, or justifiable interpretations of press releases, so I don’t promise they are correct, but they are plausible, explanatory, and interesting. I apologize for the 1,000 word wall of text, but there is a lot of good stuff.

  • This is the big one: I’m pretty sure I understand the current long term architecture plan being pursued by Intel, AMD, and Nvidia. This plan signals the end of the current style of monolithic symmetric processor cores.
    They are all apparently pursuing designs with a small N of large integer units, coupled to M >> N SIMD engines.

    • Nvidia’s “Project Denver” is a successor/big sibling to Tegra design, and appears to be the beginning of a line with 2-8 64-bit (probably) ARM cores tightly integrated with a big honking GPU-like SIMD structure for FP. The stale press release about this stuff is kind of nauseating to read, but it looks like they’re betting the farm on that design.
    • Intel’s HPC efforts are going to be based on a lot of MIC (Many Integrated Cores, successor to the Larabee stuff) parts coupled with a few big cores like the current Xeons. The MIC chips are basically large numbers of super-Atoms: tiny, simple, dumb integer units attached to big SWAR (SIMD Within a Register) units focused on SSE/AVX performance. This is less speculative than most observations, they made a pretty good press push (This for example) on this idea.
      The ring interconnects and higher per-“thread” hardware complexity are probably not a good idea in the long run (IMHO), but having an integer unit for every big SWAR engine will be a major advantage in terms of programming environment and code generation. I suspect the more cautious approach is because Intel doesn’t want/can’t afford another Itanic, where the tools couldn’t generate good code for the programming model on their intended high-end part.
    • AMD’s two current products are stepping stones to a design similar to Nvida’s – Bulldozer is a design with some ridiculously powerful x86-64 integer units decoupled from a smaller number of shared FPUs. The APU (I haven’t heard the “Fusion” name in a while) designs are CPUs tightly coupled to GPU structures. The successor parts will be a hybrid of the two – a few big, bulldozer style integer units, with a large number wide next-gen GPU SIMD structures coupled to them.

    I think this is generally a good design direction, particularly with current directions in computing in mind, but it is going to make the compiler/concurrent programming world exciting for a while.

  • AMD appears to be gearing up to abandon a fifth generation of GPGPU products. CTM, CAL, Brook+, OpenCL on 4000 series cards have all been deprecated while still shipping, and indications are that OpenCL (and general driver) support for the current architecture (4-wide VLIW SIMDs, like in the 5- and 6- series) has been relegated to second-class citizen status, while they work on a next generation architecture. The rumor is the next gen parts will be 4 independent banks of SIMD engines instead of 4-wide VLIW SIMD engines, which should be both both nicer to program and generate code for and more similar to Nvidia.
  • Nvidia is going to open source their CUDA environment. One of the primary objections to CUDA in a lot of circles is reluctance to use a proprietary single-vendor programming environment (people who have been in super/scientific computing for long have all been burnt on that in the past), and the Integer+SIMD model is going to require that not be an issue. This is assembled from information from several places, including PGI, Nvidia, and various scientific compute facilities, much of it second hand or further, but it would make sense.
  • I still don’t exactly know what went down at Infiscale, but the impression that the Perceus community was abandoned by the company, the developers fled, and it was a bad scene seems to be correct. No one I know that was there seems to be talking, but they’re all on their way to other interesting things, especially Greg Kurtzer’s Warewulf3 project at LBL.
  • The dedicated high performance compute nodes in Amazon’s EC2 cloud are actually connected as a few large partitionable clusters, users just can’t (nominally, don’t need to) see and instrument the topology like they could with a normal cluster. This is from interpreting press releases, because the people manning Amazon’s booth really didn’t want to chat (and, in fact, were kind of dicks when we tried). This explains how they’ve been getting performance out of a loosely coupled cloud — which is to say they aren’t, they just have a huge cluster attached to their cloud that shares the interface.
  • The current hard drive production problems have given SSDs the opportunity they need to become first class citizens. Talking to OEMs, the wholesale cost per capacity on HDDs almost tripled, and the supply lines aren’t all that stable, so everyone is scrambling to make things work with mostly SSDs. I saw a lot of interesting new form factors for SSDs, and several flavors flash or battery backed “nonvolatile” DRAM floating about as well, so the nature of storing data-sets is changing.
  • I saw motherboards with 32 DIMM slots (mostly AMD Interlagos based) on the floor. I saw 32GB DIMMs on the floor. I saw some shared-memory systems with multiple Terabytes of RAM in them. The standard for high memory machines has roughly quadrupled in the last year or two.
  • The number of women (not booth babes, real technical people, especially younger ones) and educators on the show floor this year was way higher than in the past. This is very good for the field.

I think that covers most of the really good stuff coming off the floor this year, although I am still processing and may come up with some other insights when I’ve had more sleep and discussion.
Also, Pictures! WOO! (Still sorting and uploading the last batch at time of posting).

Headed out to SC11 in Seattle, WA. for the week. Technical interest, travel complaints, booth hacks, advertising mockery, and schwag to follow.
