Hi,
Have anyone know about MPI Program use to measure communication
round-trip time on Cluster ( like ping command on network)
That is the program have each process run on each node on Cluster. Then
it use MPI to calculate the communication round-trip time among nodes.
Thanks

In general, what you said is "right"... for some definition of "right". :-)
Usually, benchmarking programs start a timer, do the round trip sends N times,
stop the timer, and then divide the total time by N (to get a smoother
definition of "average").
But keep in mind that there are many, many
Hi,
I'm currently doing MPI project in NUS University. My professor require
me make a monitoring tool to check the connection among processes in
Cluster. And also measure communication round-trip time.
My solution is :
1. At the source process : start MPI_Send
2. At the destination process :
