Dear Veronica,
Is this:
(1) a single large machine with 32 cpus, or:
(2) a system with 32 separate computers linked together in a network?
If (1) others have already answered, although be aware that for many
applications the throughput doesn't scale linearly with the number of
cpus. This means that there can be a ceiling beyond which allowing more
cpus to be used doesn't bring much speedup for a single process.
If (2), it can take a bit more setting up, but you can still parallelise
XDS across multiple systems. See

Regards,
Peter.

Dear all,
Which programs benefit from multi-cpu cluster? Since the physics
department is getting rid of a old 32 compute node cluster, I was
hoping to find some benefit using for crystallographic work. Looking a
ccp4wiki or google-fu did not help
Many thanks
Veronica
