It's completely different from our requirements. We share /home with the
(small) input files, and each node needs a large local /scratch space (100GB

A single file system for /home and /scratch (will your software need a common
/scratch space)? Is there any error correction in PVFS in case that a disk or
node fails? Another solution could be IBM's GPFS if you need a big and fast
common file space.
