The Story Behind a Failed HPC Startup
jbrodkin writes "SiCortex had an idea that it thought would take the supercomputing world by storm — build the most energy-efficient HPC clusters on the planet. But the recession, and the difficulties of penetrating a market dominated by Intel-based machines, proved to be too much for the company to handle. SiCortex ended up folding earlier this year, and its story may be a cautionary tale for startups trying to bring innovation to the supercomputing industry."
... is almost always wrong. As one of the principals on a large-ish (not large by world standards, 1000 cores, mainly Nehalem so approximately 100 GFLOPS) cluster, I've been very pleased that we've done things as simply as possible. Sun Grid Engine and ROCKS running on commodity 1Us delivers an economical and effective solution (no, I don't work for Sun).
Most importantly, the environment does not unduly restrict what kind of compute jobs can be run. If it can be compiled on *nix, we can probably run it. We lose to specialized hardware (GPU-based, Cell-based, ... ) in raw throughput but we make up for it in both initial price and ease of deployment. We don't even have a dedicated admin for the cluster -- we had one to set it up and he did such a good job we haven't needed to hire a replacement!
Ultimately, I feel like it's not worth paying extra in hardware and software-dev costs to save few dollars on cooling and power. Sure, you get credibility of running a "green" cluster (nevermind that you have to pay to feed and house those extra developers, which should legitimately come out of your carbon budget) but you end with with a far less useful product.
Long Live X86(_64)!
