Hi, Thanks its has worked but when i tried to run for a 2 nodes , i have got the following error
[master@ip-10-80-106-70 ~]$ mpirun -n 2 --hostfile hostfile out Permission denied (publickey,gssapi-with-mic). -------------------------------------------------------------------------- A daemon (pid 9923) died unexpectedly with status 255 while attempting to launch so we are aborting. There may be more information reported by the environment (see above). This may be because the daemon was unable to find all the needed shared libraries on the remote node. You may set your LD_LIBRARY_PATH to have the location of the shared libraries on the remote nodes and this will automatically be forwarded to the remote nodes. -------------------------------------------------------------------------- -------------------------------------------------------------------------- mpirun noticed that the job aborted, but has no info as to the process that caused that situation. -------------------------------------------------------------------------- mpirun: clean termination accomplished [master@ip-10-80-106-70 ~]$ so please help me in solving this. Thanking you.
