Hi! Problem with random segfault for java-programs solved by adding mca options:
$path_to_openmpi_bin/mpirun -np 1 -mca btl self,sm,openib $path_to_java_bin/java randomTest Thanks to Eshsou Hashba and Michael Kalugin! But i get other problems! If I start mpirun from manager-node (without ssh-login to calculation node) $path_to_openmpi_bin/mpirun -np 2 -host node188,node189 -mca btl self,sm,openib $path_to_java_bin/java randomTest I get next error: $openmpi1.10_folder/bin/orted: error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory -------------------------------------------------------------------------- ORTE was unable to reliably start one or more daemons. This usually is caused by: * not finding the required libraries and/or binaries on one or more nodes. Please check your PATH and LD_LIBRARY_PATH settings, or configure OMPI with --enable-orterun-prefix-by-default * lack of authority to execute on one or more specified nodes. Please verify your allocation and authorities. * the inability to write startup files into /tmp (--tmpdir/orte_tmpdir_base). Please check with your sys admin to determine the correct location to use. * compilation of the orted with dynamic libraries when static are required (e.g., on Cray). Please check your configure cmd line and consider using one of the contrib/platform definitions for your system type. * an inability to create a connection back to mpirun due to a lack of common network interfaces and/or no route found between them. Please check network connectivity (including firewalls and network routing requirements). -------------------------------------------------------------------------- If I throw LD_LIBRARY_PATH (that contain path to libimf.so) via -x option to mpirun: $path_to_openmpi_bin/mpirun -x LD_LIBRARY_PATH -np 2 -host node188,node189 -mca btl self,sm,openib $path_to_java_bin/java randomTest then I get same error (orted: error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory). How I can throw lib path for spawned mpi processes and orted? I don't have root-privileges on this cluster.
