Dear all, I am having trouble running an MPI code across multiple cores on a new computer cluster, which uses PBS. Here is a minimal example, where I want to run two MPI processes, each on a different node. The PBS script is
#!/bin/bash #PBS -l walltime=00:01:00 #PBS -l mem=1gb #PBS -l nodes=2:ppn=1 #PBS -q batch #PBS -N test mpirun -np 2 ./code.o and when I submit it with $qsub script.sh I get the following message in the PBS error file $ cat test.e1234 [shbli040:08879] mca_base_component_repository_open: unable to open mca_plm_tm: libcrypto.so.0.9.8: cannot open shared object file: No such file or directory (ignored) [shbli040:08879] mca_base_component_repository_open: unable to open mca_oob_ud: libibverbs.so.1: cannot open shared object file: No such file or directory (ignored) [shbli040:08879] mca_base_component_repository_open: unable to open mca_ras_tm: libcrypto.so.0.9.8: cannot open shared object file: No such file or directory (ignored) -------------------------------------------------------------------------- There are not enough slots available in the system to satisfy the 2 slots that were requested by the application: ./code.o Either request fewer slots for your application, or make more slots available for use. ————————————————————————————————————— The PBS version is $ qstat --version Version: 6.1.2 and here is some additional information on the MPI version $ mpicc -v Using built-in specs. COLLECT_GCC=/bin/gcc COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/lto-wrapper Target: x86_64-redhat-linux […] Thread model: posix gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) Do you guys know what may be the issue here? Thank you Best,
