I haven't looked at PVFS for nearly a decade, so my understanding could be way out of date. Sorry if this is a stupid question; I'm hoping PVFS might fill some requirements I'm looking at.
Is it typical to use compute nodes as PVFS file servers? Is it even possible (i.e. it isn't w/ Lustre)? If so, while striping across I/O nodes looks to be the default, is there any provision for file affinity... i.e. files migrating to the nodes using them? If striping is the only choice, and compute nodes serve the I/O too, then a job running on one set of nodes could be using files striped across another set of nodes in use by another job, causing both jobs to loose performance, correct? Are there any links to PVFS performance over IB?
