Marrying NVIDIA Tesla and InfiniBand?
My friend is working on a research project dedicated to many-core architectures, such as NVIDIA’s GPUs or Intel’s Xeon Phi, that have lots of simple cores best suited to straightforward computations....
View ArticleFinally, A Topology-Aware MPI Implementation
Good news from the Supercomputing-2012 (SC12) conference: ten collaborators (including a talented team led by Dr. Dhabaleswar K. Panda) presented a paper on a new approach for assigning processes to...
View ArticleReal Cost Comparison of Fat-tree and Torus Networks
Thanks to Mellanox Technologies, our tool that designs fat-tree and torus networks now operates with real life prices for InfiniBand hardware. Mellanox kindly provided list prices for the previous...
View ArticleMany-core and InfiniBand: Making Your Own CPUs Gives You Independence
The headline sounds like the obvious thing: of course, if you can make your own CPUs for your projects, then you don’t have to rely on CPU manufacturers. “But wait”, you would ask, “Aren’t CPU design...

There are a lot of good research projects going on in Europe: if you didn’t hear about them, it is simply because they are not receiving the media attention they deserve. One of such projects is the...
View Article648-Port InfiniBand FDR Switches Added to the Database
It’s Christmas time… Just a few hours, and year 2013 will become a thing of the past. Gone with it will also be the outdated InfiniBand QDR hardware that was — until today — used in the fat-tree design...
View ArticleBuilding Fat-Tree Networks with Ethernet Hardware
Fat-tree networks work very well with InfiniBand hardware. At the same time, a fat-tree built with Ethernet switches may not always work: this is because switches must be able to discover multiple...
View ArticleExascale Supercomputers: Anything but Cheap
Science and engineering both rely on the continuous increase in supercomputing performance. Back in 2009, it was believed that exascale machines will become available by 2018 — nine years ahead seemed...
View ArticleCost: The Biggest Pothole on the Exascale Road
Recently, industry analyst John Barr wrote at the ISC blog about “Potholes on the Road to Exascale”. John speaks about a unified programming environment that should be able to support all sorts of...
View ArticleWill We Ever See InfiniBand in Desktop Computers?
[Update: the post is not actually about InfiniBand as such, it’s more about convergence that can be brought by the new Intel Omni Scale Fabric :-) Please see the comment below the post, and thanks for...
