Dear Igor,
Thank you very much for the clarifications, but now I'm trying to run over a cluster, if I send the executable file that I just compiled to the cluster, and I try to run it with mpirun/mpiexec, it complains about not finding the file libx10.so, which ofcourse is a library file for X10 that I have locally. I'm sorry but I'm a newbie in this, do you have any suggestions?
