Hi all,
we are facing problems while executing mpi programs.if all the client
nodes are up, then the mpi application works fine. But
in case if any one of the node is down then the execution terminates.
Here is one sample output:(specifically oscarnode2 is dead)
# mpirun -np 4 ./a.out
oscarserver.oscardomain
Sun Mar 27 23:13:15 IST 2005
oscarnode1.oscardomain
Sun Mar 27 23:13:25 IST 2005
ssh: connect to host oscarnode2 port 22: No route to host
p0_14474: p4_error: Child process exited while making connection to
remote process on oscarnode2: 0
Killed by signal 2.
/opt/mpich-1.2.5.10-ch_p4-gcc/bin/mpirun: line 1: 14474 Broken pipe
/home/oscartst/suresh/./a.out -p4pg
/home/oscartst/suresh/PI14350 -p4wd /home/oscartst/suresh
But it should not affect the performance of the cluster even if one
of the node is dead right?
Eagerly waiting for the response.
