I am trying to compare the times of some apps on real MPI vs SMPI on a few ARM nodes. I would like your help to configure my SimGrid platform. My platform is a Cluster. I would like to know if there is any way to estimate the speed property of my real host. Besides, how the calibrate_flops.py is related to the speed. I got the calibrate_flops.py script from here. > http://simgrid.github.io/SMPI_CourseWare/topic_understanding_performance/ > matrixmultiplication/ > By now, I setted the *speed* value randomly, and setted the *smpi/host-speed* I got from the calibrate_flops.py I compiled both apps (smpi and mpi) with -O3. But then if I fit the speed to reduce error on a cpi example, I get some error on another app doing a simple addition on loop. Can I estimate that speed parameter? or it should be fitted mannually?
