build your own Sony PS3 cluster supercomputer


Recommended Posts

Our community guide allows you to set up your own MPI (Message Passing Interface) based supercomputer cluster with the Playstation 3. This guide was co-written by Gaurav Khanna, based on his previous work on the Gravity Grid and is a current run-time environment for the research of co-author (Chris Poulin), based on his current work in distributed pattern recognition. As such, we currently utilize the Fedora Core for this infrastructure and illustrate a "how-to" below. NOTE: We focus on the Fedora 8 distribution, due to prevalence of Fedora and its Cell SDK (3.0) compatibility. Finally, this content should be considered open source, and here is the license

My comments on this are the same as when people were trying to cluster XBox units back in the day: there simply isn't enough RAM in these to make them useful.

 

Yes, they have uber processors that can do all sorts of floating point magic. But the reality is unless you're crunching small data sets (and lets face it, if you're clustering, you're not dealing with "small") then anything less than 4-8GB pure minimum per node just won't make the grade (and even then, I'm seeing workloads now that require 32GB+ per node).

 

A company called Mercury in the US makes a Cell-based PCI-Express card. It features 1GB of very fast XDR RAM, and 4GB of "slow" DDR working RAM. That's per Cell processor, so you could fill a standard workstation with 4-5 of these, giving you 25GB+ of RAM in a box.
