Hi everyone. I have any questions about Barrier Collective Communication. Have anyone ever test Barrier in Intel Micro Benchmark in large number of processes (in case 1 process/node and more than 100 nodes) ? I would like to know about the average time (usec)  Does it chance about average time will decrease in large scale ?

Thank you.
