This connects back to an earlier posting of mine which drew a "dead cat bounce" for a response ... ;-) ... , but you should also definitely look at both the offerings of PeakStream and RapidMind. PeakStream (like CUDA) provides libraries and a development environment (their current focus is GPUs), but abstract the idea of co-processing one step further to a virtual machine (Mitrion-C does the same for FPGAs) connected to a master serial processor. Any additional co-processing resource (any of several flavors of GPUs, a CELL SPE, or non-rank zero,homogenous multi-cores, etc.) can provide the horse power for the data parallel accelerations. They claim that once a particular backend for the VM is available you will be able run your code without a recompile on it or any other supported backend. I think the RapidMind product is similar. Peakstream has a nice white paper on their web site and the main Rapid Mind paper is:
Data-parallel Programming on the Cell BE and the GPU using RapidMind Developoment Platform by Mike McCool. The jist of my earlier posting was "Does such a data-parallel VM abstraction have a future in an HPC world of heterogeneous on and off-chip co-processors?" Its presence as part of the Mitrion-C and PeakStream programming models suggests someone with money believes as much. rbw > _______________________________________________ > Beowulf mailing list, Beowulf@beowulf.org > To change your subscription (digest mode or unsubscribe) visit > http://www.beowulf.org/mailman/listinfo/beowulf > -- -- Richard B.
