Hi Paolo, Thank you for your assistance. that is looking better,
This is the line I added to the script check-pw.x.j ... PARA_PREFIX="mpiexec -n 60 -f /home/user/mpiMachinefile.txt" when launched with "./check-pw.x.j" many 100% processes showed on each system. however I am not sure what it was doing because nothing else happened besides the text output "Checking atom...". Usually this test completes in less than an hour on 1 core, many cores should reduce the completion time, after a couple of hours I saw nothing more than "Checking atom..." so I pressed Ctrl+C on the terminal and it printed some more information... $ ./check-pw.x.j Checking atom...Killed by signal 2. [mpiexec at server4] HYDT_bscu_wait_for_completion (./tools/bootstrap/utils/bscu_wait.c:99): one of the processes terminated badly; aborting [mpiexec at server4] HYDT_bsci_wait_for_completion (./tools/bootstrap/src/bsci_wait.c:18): bootstrap device returned error waiting for completion [mpiexec at server4] HYD_pmci_wait_for_completion (./pm/pmiserv/pmiserv_pmci.c:352): bootstrap server returned error waiting for completion [mpiexec at server4] main (./ui/mpich/mpiexec.c:294): process manager error waiting for completion FAILED with error condition! Input: atom.in, Output: atom.out, Reference: atom.ref Aborting $ I also tried adding "-wdir /usr/local/espresso-4.2.1/tests" at the end of PARA_PREFIX and gave the same result. I also tried uncommenting PARA_POSTFIX="./check-pw.x.j" and it gave the same result. thanks & regards, Nick > -----Original Message----- > From: giannozz at democritos.it > Sent: Wed, 8 Dec 2010 09:42:06 +0100 > To: pw_forum at pwscf.org > Subject: Re: [Pw_forum] QE and mpich2, Linux > > > On Dec 8, 2010, at 8:15 , ac.rain at inbox.com wrote: > >> $ mpiexec -f ~/mpiMachinefile.txt -n 10 -wdir /usr/local/ >> espresso-4.2.1/tests ./check-pw.x.j > > the correct way to start the tests in parallel is to edit PARA_PREFIX > and PARA_POSTFIX > in the "check-pw.x.j" script > > P. > --- > Paolo Giannozzi, Dept of Chemistry&Physics, Univ.
