Hello I am using OpenMPI ver 1.8.1 on a cluster of 4 machines. One Redhat 6.2 and three busybox machine. They are all 64bit environment.
I want to use --preload-binary option to send the binary file to hosts but it's not working. # /mpi/bin/mpirun --prefix /mpi --preload-files ./a.out --allow-run-as-root --np 4 --host box0101,box0103 --preload-binary ./a.out -------------------------------------------------------------------------- mpirun was unable to launch the specified application as it could not access or execute an executable: Executable: ./a.out Node: box0101 while attempting to start process rank 17. -------------------------------------------------------------------------- 17 total processes failed to start # If I sent the binary by SCP beforehand, the command works fine. SCP is working fine without password between the hosts. Is the option supposed to work? Thank you, Eiichi
