Dear Dr.Kohlmeyer,<br> <br> Thanks for your reply. <br> <br> I am just one user of our cluster, that is, I am not the system administrator. I do not know the detail of the installation of softwares there. But MPICH was there, and can be launched by "module add". And I was told that MPICH was installed ourselves, not bundled with the machines.<br> <br>The command line I used to do "configure" is "./configure MPI_LIBS="-L/opt/mpi/tcp/mpich-pgi/lib -lmpich -lfmpich"<br> <br> Could you please give me more hints what I should do to figure out this problem?<br> <br> By the way, have you ever used pathscale to compile espresso? It seems to be possible from the update information for espresso3.1.1. We have pathscale and mpich for pathscale work for VASP on our cluster.<br> <br> Best,<br> <br> Stargmoon<br> <br><b><i>Axel Kohlmeyer <akohlmey@cmm.chem.upenn.edu></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px;
