mpdboot -fails

Maurice_Breault — Tue, 02 Jul 2013 13:52:26 GMT

using the following parameters (single node so not mpd.hosts file required)

mpdboot -r ssh --verbose

"get the following"
[admin@localhost ready_GNU]$ mpdboot -r ssh --verbose
running mpdallexit on localhost.localmpi
LAUNCHED mpd on localhost.localmpi via
mpdboot_localhost.localmpi (handle_mpd_output 998): from mpd on localhost.localmpi, invalid port info:

mpd.run()

Is there something I am missing?

Is there a minimum # of cores supported?

Hi Maurice,

Hi Maurice,

What does your /etc/hosts file look like? What is the output from ifconfig?

Also, can you run with mpirun? This does not require booting an MPD, as it uses Hydra instead.

This was resolved by using the actual hostname instead of localhost.localmpi.
