Dear Sir/Madam, We, in our research group, are trying to compile parallel version of Quantum Espresso v4.0.5 on our beowulf linux cluster.
Several of our attempts over the past couple weeks have failed. Even when parallel compilation seems to have succeeded, we notice no difference in performance between serial & parallel runs. If the fellow users of Quantum Espresso could please guide as with configure/Makefile tips/tricks, we will greatly appreciate it. The cluster is 64-bit, built using NPACI ROCKS software along with Red Hat Enterprise Linux. It has Intel v9.1 compilers, with which we have compiled several other programs (VASP/SIESTA/SMEAGOL) and they all seem to be running fine with SGE job submission engine. Thanks in advance for your time and help! Best regards, Gowtham -- Gowtham Department of Physics Michigan Tech University Houghton, MI http://sgowtham.net/
