AMD Gains In the TOP500 List
MojoKid writes "AMD recently announced its share of the TOP500 supercomputer list has grown 15 percent in the past six months. The company credits industry trends, upgrade paths, and competitive pricing for the increase. Of the 68 Opteron-based systems on the list, more than half of them use the Opteron 6100 series processors. The inflection point was marked by AMD's launch of their Magny-Cours architecture more than a year ago and includes the twelve-core Opteron 6180 SE at 2.5GHz at one end and two low-power parts at the other. Magny-Cours adoption is important. Companies typically don't upgrade HPC clusters with new CPUs, but AMD is billing their next-gen Interlagos architecture as a drop-in option for Magny-Cours. As such, it'll offer up to 2x the cores as well as equal-to or faster clock speeds."
That's hardly a "random list". And this is a site about technology. Do you think it would be irrelevant for a site about gaming consoles to mention that the Kinect increased the Xbox's share of exercise games (or whatever) ?
Supercomputing designs are a rather good real-world benchmark of CPUs, because they take into account cost, density, ease of deployment, etc..
More interesting than the share of the top 500 list, though, is the fact that AMD holds the #3 spot, ahead of Intel (whose first system comes in at #4) and both are behind a GPU-based system (using Nvidia Tesla chips, at #2). This is probably a good indicator of things to come, and explains why AMD is betting so heavily on integrating the GPU into its overall system architecture, and why Intel has finally started serious work on GPUs.
#1, by the way, is held by a SPARC system.
The top500 site has its own take on highlights:
http://www.top500.org/lists/2011/06/press-release
- The two Chinese systems at No. 2 and No. 4 and the Japanese Tsubame 2.0 system at No. 5 are all using NVIDIA GPUs to accelerate computation, and a total of 19 systems on the list are using GPU technology.
- China keeps increasing its number of systems and is now up to 62, making it clearly the No. 2 country as a user of HPC, ahead of Germany, UK, Japan and France.
- Intel continues to provide the processors for the largest share (77.4 percent) of TOP500 systems. Intel’s Westmere processors increased their presence in the list strongly with 169 systems, compared with 56 in the last list.
- Quad-core processors are used in 46.2 percent of the systems, while already 42.4 percent of the systems use processors with six or more cores.
- Cray defended the No. 2 spot in market share by total against Fujitsu, but IBM stays well ahead of either. Cray’s XT system series remains very popular for big research customers, with three systems in the TOP 10 (one new and two previously listed).
In my opinion, the newest & most important trend in high performance computing is the advent of accelerators like GPUs.
The supercomputer I use daily is one of these new AMD based ones in the TOP500. It is a sweet machine. My software (custom engineering simulation written in C++) scales perfectly on it all the way out to over 10,000 cores.
The memory architecture is really excellent as well. With our old Intel based cluster we wouldn't load up every core on the node because of memory contention. But hyper-transport with NUMA completely negates the need to do that. We routinely fully load the nodes on the new machine without any trouble at all.
If AMD keeps it up they are going to find a lot of business in the high-end computing segment.
Well I'd say its also news as many of the guys here are in charge of purchases and this shows AMD still has some competitive server offerings, and as someone who remembers what it was like when there was only Intel (crazy ass pricing, lousy chips, insane motherboard costs, etc) having competition is VERY important!
I'd add these gains were done in spite of Intel doing everything but setting the AMD factories on fire trying to kill AMD. They rigged their compiler (and still are BTW) to put out shit code if it runs on an AMD CPU, they bribed the OEMs so much that there were several quarters where the ONLY profits Dell saw were Intel kickbacks, and Toshiba said their kickbacks were so generous they were "like cocaine" to the OEMs.
So I'd say that AMD making gains despite Intel doing everything but breaking their employee's kneecaps just shows they still have some competitive spirit. I personally have switched my shop to AMD only after finding out about the bribery and compiler rigging and my customers couldn't be happier. Their netbooks and laptops all have smooth video and are easy to hook to a TV via HDMI thanks to the Radeon IGPs, their desktops are likewise great with smooth 1080p video and hardware acceleration of all the major formats as well as hardware transcoding, their triples and quads make a great centerpiece for a good cheap media box or HTPC, all in all they make a great consumer box that will do all your average person will ever want to do at a price they can easily afford without breaking the bank.
So I'm personally glad for TFA, as it shows me they have competitive server chips to go with their excellent desktop and notebook lines. And frankly you should be happy too as real free market competition is good for everyone. or do you honestly think Intel would have a chip that costs less than $1000 if it weren't for AMD?
ACs don't waste your time replying, your posts are never seen by me.
Well, it is of interest to people who are interested in supercomputers.
People who develop software for those beasts like to know how things are changing. They may not need to know the intimate details since compilers and libraries will handle most of that, but they may want to throw together a small cluster to test emerging technologies. (This is particularly true in recent years since small clusters based upon AMD/Intel CPUs and AMD/Nvidia GPUs are within reach of individuals.)
Stockholders though couldn't care less. The number of units is too small and the prestige counts for nothing unless it translates into sales in other markets.
It's a bit more. Supercomputers push bus speeds and floating-point calculations to the limits. Much of the hardware, these days, is commodity and these two criteria are important in gaming, computer art (such as rendering). The former is also important in embedded computing (such as phones) since data streaming is limited by maximum sustained bus speed.
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
"Any proof of these claims of compiler tampering?"
This is a well known issue with the intel compiler which has been fixed since. The story is told on wikipedia in the criticism section of http://en.wikipedia.org/wiki/Intel_C%2B%2B_Compiler
The problem is so well known, that people wrote software to patch the code produced by the intel compiler to make it work properly on AMD processors such as http://code.google.com/p/patch-authenticamd/
"So why would you be using an intel compiler on AMD cpus?"
One of the interest in using the x86 instruction set is to be binary compatible so that you can use the code generated by any compiler. The intel compiler is a very good compiler, why not use it ? VIA also produces x86 processors you can use the binaries generated by the intel compiler on it. These technologies are designed to be compatible.
"Does AMD not write one?"
AMD contributes to http://en.wikipedia.org/wiki/Open64 and to GCC.
"Your third paragraph reads like an advertisement,"
I agree on that one.
