I have setup a cluster on Ubuntu 12.04 machines (using the steps outlined here: https://help.ubuntu.com/community/MpichCluster)

The environment variable PATH is set. The code is compiled on the master node and executed on the master node. After execution of the code, the slave nodes crash, i.e. the slaves start rebooting, debug statements on the display indicate kernel panic. The slaves have to be restarted. This is not exactly reproducible as it does not happen every time, but sometimes.

Hi Vaibhav,

Can you give us some details of how the slaves panic?

Hello there!
I have setup a small cluster (only 3 nodes - 1 master, 2 slaves).
I was trying to run a sample program by using this command:

    $MPI_INSTALL_DIR/bin/mpirun -n 9 --machinefile machinefile ./a.out


Contents of machine file:

    host1:3
    host2:3
    host3:3


Please help.
