How big are the apps? Assuming they only use one or two gigs of memory
a piece, you should be able to have a 32-bit machine with lots of RAM.
Or even an opteron with lots of RAM with a 32-bit OS on it. That would
save you from having to worry about any 32 vs 64 bit issues.
With that said, having a 64-bit head node and 32-bit compute nodes isn't
difficult. Like Reuti said, just make sure you're careful about where
you compile your code.
