mpdboot error: Failed to establish a socket connection with node:53317 (111, 'Connection refused')

[Minia_Oseguera]

Hi, i have this error when i run the followed script on a cluster:

--------------SRIPT---------------------

#!/bin/bash

# Start mpd daemons on all compute nodes

echo "Shutting down any existing mpd daemon"

mpdallexit

echo "Starting MPI on all nodes"

mpdboot -r ssh -n 8 -f $HOME/mpd.hosts

echo "MPI was initialized on the following nodes:"

mpdtrace

-------------- ERROR --------------------

Anyone knows why is happening that? thanks!

Hi Minia,

Could you please give us information about MPI library.
And please confirm that you have set password-less connection between nodes.
Try to run: 'ssh compute-00-01 hostname'

Regards!
