There are a number of MPI benchmark programs out there, including NetPipe, OSU, etc. All of them do some form of message exchange and report latency and bandwidth as a function of message size.
You'd have to look into them to see if they match your specific communication pattern. A quick web search for MPI benchmark will yield a lot of hits.
My question is " In MPI community , Is there a program like this ? "
Describe about this program: I have the cluster to run MPI Program. But before running, I want to check the connection and to measure some performance features of this system like latency, bandwidth ... It means i created the number of processes is equal to the number of nodes. And it actually each process will run in each individual node. And then, i use blocking, non-blocking , synchronous... communication to communicate among processes. And then, I can measure the latency, bandwidth... from one node to another node. It like test the system before running MPI Program
Is anyone know about this program with the same function ? Thanks and hope to see your reply soon .
