Hello guys, let me explain my question with an example: Assume I want to run 24 thread on my Beowulf cluster which use MPICH2 as the MPI library. I run these 24 threads on six servers giving each 4 threads with "mpiexec" command. Can I change this configuration during the *run time* for example do it as 4*6 using 4 server and giving each 6 thread? I am looking for something like task affinity in one server which you say what core do which pid with "taskset" comand without stopping the program. Let me know,
Thanks Reza
