How to check performance of your HPC cluster?
Hello Everybody,
I have few queries :
Do you have any idea how to check the performance of HPC cluster having mpich on top of centos 6.2?
Are there any standard programs (like FFT, graphics rendering etc) to check the performance of mpi cluster with single node and multiple nodes?
Can we check the performance of single core and dual core?
Can we benchmark small cluster of 4 nodes or is benchmarking softwares are only for big clusters?
Thanks..
