Hello, I have two linux machines, each running Open MPI 1.6.5. I want to use the preload binary command in an appfile to execute a binary from the host on both the node and the host during mpirun. Right now I am using an appfile with the contents: #appfile.test
-host user@remotehost --preload-binary -np 1 run_date -host localhost -np 1 run_date where 'run_date' is an executable that creates a text file with the current date. I run the appfile using the command: mpirun -app appfile.test I enter user@remotehost's password when prompted and then immediately receive an error: -------------------------------------------------------------------------- WARNING: Remote peer ([[53924,0],1]) failed to preload a file. Exit Status: 256 Local File: /tmp/openmpi-sessions-user@remotehost_0/53924/0/run_date Remote File: run_date Command: scp localhost:/home/user/appfileTest/run_date /tmp/openmpi-sessions-user@remotehost_0/53924/0/run_date Will continue attempting to launch the process(es). -------------------------------------------------------------------------- -------------------------------------------------------------------------- mpirun was unable to launch the specified application as it could not access or execute an executable: Executable: run_date Node: user@remotehost while attempting to start process rank 0. -------------------------------------------------------------------------- After this error, I get returned to the command line to see that the 'run_date' binary has been executed on the localhost but not the remotehost. I have been able to run on both machines by manually placing the binary on the remotehost and removing the '-preload-binary' command from the appfile, however I need the appfile to place the binary for me. I have also tried setting the remote machines directory using '-wdir' but receive the same error. Do you guys know what the issue is?
