Cluster Design Tools Updated (ver. 0.8.4), SADDLE Included
The recent release of Cluster Design Tools, version 0.8.4, is different from previous releases. First, it now incorporates SADDLE, a Python-based scripting language for automated design of cluster supercomputers and data centres, which was announced earlier. Second, it now includes … Continue reading
Will 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 your time!] When I … Continue reading
SADDLE Presented at the ISC’14 Conference in Leipzig
SADDLE, the CAD tool for cluster supercomputer and data centre design, has just been presented at the ISC’14 conference in Leipzig, Germany. SADDLE can help you choose the best hardware by analysing its price/performance ratio, and then it will design … Continue reading
Cost: 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 computing devices of the future. That’s right: … Continue reading
Exascale 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 like a lot of time. No one knew how … Continue reading

Most cooking recipes are formulated improperly: they list actions required to prepare food, but fail to explicitly mention which of those actions can be run in parallel. This leaves you guessing how much time you could save if you added … Continue reading
Building 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 paths in a topology and balance traffic among … Continue reading
