You mean storage right?

OK, the clusters I use have local disks on each node mounted as /tmp
just for this. It's really nice not to have to deal with file
contention, NFS and so on.

So the nodes have enough memory to hold the whole data set, but not
enough storage?

They can't ask for the pieces they need? Are there so many particles
that each process would have a particle in most pieces? Would it make
sense to break the data up and pass particles instead of data?
