mpistat is a tool for efficiently gathering file system statistics from distributed parallel file systems using a large number of worker nodes.
Gathering statistics (i.e. `stat` output) from large distributed parallel file systems such as Lustre can take a very long time when run on an individual machine. We developed mpistat to be able to take advantage of the parallel nature of such filesystems by running the `stat` operations in parallel across a large number of worker nodes, using MPI to distribute the work.
