Dear Forum I compiled a couple of days ago, openmpi 1.4 and quantum espresso, however when I sent the job to the queue system. The nodes show that the command was executed with the "-np 8" option, but the output not :
???? Parallel version (MPI), running on??? 64 processors ???? R & G space division:? proc/pool =?? 64 and with openMPI show me different status : Parallel version (MPI), running on 64 processors K-points division: npool = 8 R & G space division: proc/pool = 8 I'm a little bit confused, I don't understand what I did bad in the compilation procedure of openmpi1.4 or espresso. OpenMPI Settings ./configure --prefix=/local/openmpi --disable-dlopen --enable-mpirun-prefix-by-default --enable-static --enable-mpi-threads --with-valgrind --without-slurm --with-tm --without-xgrid --without-loadleveler --without-elan --without-gm --without-mx --with-udapl --without-psm CC=icc CXX=icpc F77=ifort FC=ifort And the quantum espresso setting in the compilation are located here : http://www.lpmd.cl/jperalta/uploads/Site/make-ompi.sys Really every help I appreciate a lot, because the difference in time calculations, is huge using the -np for my cases.
