We ported Grid Engine (ie. OGS/GE) to ARM Linux in the GE 2011.11
release, but we haven't encountered huge demands yet. May be when

you really need to look at where your code is spending its time.
the seq stuff I see is quite IO-intensive, sometimes memory-intensive.

On a bang for the buck, horsepower wise, it's usually better to go single
processor than spread the load across many smaller processors, unless your
application can make use of parallelism (so while you get fewer MIPS total for
a given amount of cash, your problem completes faster, and that's wo
Yeah did you already check which big capital S processor the
raspberry Pi has?
Single core ARM and low clocked.
If you cluster ARMs, why not get for a few dollar more a quadcore
1.7Ghz ARM A9.
For example:
