Hi all
We have a small cluster but some users need to use MPI-IO. We have a NFS3shared partition but you would need to mount it with special options who would hurt performance. We are looking into a nice parallel file system to deploy in this context. We got 4 boxes with a 500Gb disk in each, for the moment, connected with Gb. We have another Gb connection dedicated to the MPI traffic.
We need an open source solution, we are looking into PVFS and Gluster (but from what we see, Gluster doesn't quit fit the bill? It's more a distributed filesystem than a parallel filesystem... or are we taking the wrong turn on our reasoning, somewhere about this?)
Anyway your thoughts and experience would be very welcomed so we can make a better decision.
