Visualization of PVFS2 Server Activities (Extended Abstract)

With parallel I/O we are faced with the situation that we do not have appropriate tools to get an insight into the I/O server behavior depending on the I/O calls in a parallel program. We present an approach that enhances a trace-based tool in a way to show us client and server behavior in relation to each other. We focus on the parallel le systems PVFS2 and the MPI tool Jumpshot.
