Hi Satish, thanks very much for quick infos!
I understand that I have to use mpirun or mpiexec. (I still dont know how the system knows which procs can be used?) (in rexecshell one can fill in a list with the node-names) my questions arise out of the following situation: under cygwin: 1. I downloaded Petsc and made the necc. definitions 2. make all (everything ok!) 3. make test ( (everything ok!) under the tests there are also test for parallelizations! I still dont know how Petsc was doing this tests??? I may have missed something , but I never found a call to mpirun or mpiexec? perhaps you can explain it?
