For Tiger - most stuff you'd want to run on a cluster will be 64bit. That is the kernel and most userland tools will be 64 bit, however most 'high level' toolkits (e.g. Cocoa) will still be 32bit. I don't see many Carbon/Cocoa apps being run on a cluster needing large memory spaces, so that probably doesn't matter :) cheers Michael
