Portable Hardware Locality (hwloc)

From the in your neighborhood department

The Hardware Locality (hwloc) team, which is affiliated with the nearby OpenMPI team, has announced the release of version 1.0 of hwloc.

hwloc provides command line tools and a C API to obtain the hierarchical map of key computing elements, such as: NUMA memory nodes, shared caches, processor sockets, processor cores, and processor "threads". hwloc also gathers various attributes such as cache and memory information, and is portable across a variety of different operating systems and platforms.

The hwloc team considers version 1.0 to be the first production-quality release that is suitable for widespread adoption. Please send your feedback on hwloc experiences to our mailing lists (see the web site, above).

Thanks team, keep up the good work, and don't go anywhere.

March Silicon Madness

Read about three new processors hitting the market and nothing about basketball

I waited to make a joint news story about the new processors that were due to arrive this month. In this way, you could click from here to some good reviews and insights rather than hunting on the Internet. We are now permanent residents of multi-core-ville. Remember those single core processors? Seems like a while ago. Although, I bet you still use hardware that has some of these "old" processors. Of course the Intel and AMD announcements are pointed toward servers, but the goodness always trickles down. Other than making the Internet faster, I am still trying to figure out what Joe or Jane Sixpack will do with 6-cores in their bargain of the week lap/desktop from the big box store.

NVidia: 2009 Top Ten Round-up

In case you were not paying attention

I usually don't post things vendors send to ClusterMoney because we are not a big time news site (nor to I care for marketing piffle). I will at times summarize some important news and events with enough links to send you on your way to HPC enlightenment. Each Year NVidia sends me a year in review which is a good summary of Tesla HPC events -- complete with many URLs so readers can explore further. [A note to vendors: Company news (aka press releases) with URLs and good background and no jargon may get posted here.] The NVidia round-up begins below:

NVIDIA Tesla - 2009 Year in Review

GPU Computing had a ground breaking year in 2009. In just two and a half years from its launch, the Tesla brand has truly established itself in the HPC community. This wouldn't have happened without the efforts of real GPU Computing pioneers such as Prof. Wen-mei Hwu at University of Illinois who taught the very first courses in parallel programming on the GPU and Prof. Satoshi Matsuoka at Tokyo Institute of Technology who put the first Tesla GPU-enabled supercomputer onto the Top 500 (Top 30 in fact), just one and half years after we launched the brand.

A "tipping point" is defined as a level at which momentum for change becomes unstoppable - we genuinely believe that we are witnessing the tipping point for GPUs in the high performance computing space and the SC09 conference in Portland, Ore. in November cemented that belief.....but we'll come to that in due course :)

Some conveniently late news (after SC09) for the HPC market

I may write more about SC09 in the next few weeks, but for now the video is starting to show up on at Linux Magazine and I already posted a SC09: Three Trends Worth Watching over at HPC Community. You can get a good feel for things from those two articles. I'll also be posting more video on Linux Magazine over the next several weeks.

The weeks after SC are usually quiet as the holidays approach. This year seems to be a little different. There have been more than a few interesting annoucements about the HPC market. I find it kid of interesting how all these show up after SC09. Perhaps these are the kind of announcements you don't want gobbled up by the press. In any case, I have collected the stories and added a little commentary to each. An interesting time in HPC to say the least.

Automatic Parallelization for GCC (beta)

That is parallelization not paralyzation

Recently, I had a conversation with Dmitry Tkachev of T-Platforms. Of course many of you may not know about T-Platforms because you don't buy clusters in Russia. Dmitry was not trying to sell me a cluster, however. He was pointing me to some auto-parallelizing compiler technology from a Russian software company called Optimitech.

I asked Dmitry if he could provide a brief summary of what Optimitech was developing for the HPC crowd as they offer some auto-parallelizing patches to gcc/gfortran. In any case, I'll let Dmitry continue (I helped with the grammar a bit, although some may consider my help questionable.)
