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
64-bit ARM finally gets into the mainstream, more people will deploy
ARM HPC clusters.

Note that the Raspberry Pi does not have ECC memory, which is almost a
standard feature even in low cost servers. Are you going to run each
batch job twice and compare the results to make sure that the memory
was not corrupted when the job was run??
And, if you are looking for FLOPS/$, then any modern x86 processors
can easily beat the Raspberry Pi. If you are looking for FLOPS/W, and
if the problem can be broken down nicely (or else it would suck
running on a large number of Raspberry Pi nodes too), then a single
GPU node can beat the Raspberry Pi in FLOPS/W easily as well.
