It's also been posted on the INQ:
It's very interesting from the design point of view, but I'm less
convinced by the price tag argument.
Stanford University recently purchased a 276 dual-socket quad-core HPC
cluster, which is capable of 20.6TFlops (peak) and actually achieved
15.5TFlops (it has been ranked #54 in the latest Top500 list).
The cost per GFlops has been $109, which is indeed more expensive than
the microwulf's $94/GFlops, but still far from being "five times as
much", as claimed by the INQ article. Besides, the price included
software (a commercial scheduler) and support, management capabilities,
50TB high-performance storage, an administration GigE network and a DDR
I guess it's easier to lower the cost per GFlop on large scale clusters,
but I'd just wanted to put this into perspective, and show that you
don't necessarily need to build your cluster from scratch to get
comparable price/performance ratios.
