IntelĀ® MPI Library Reference Manual for Linux* OS
This optional configuration file contains an mpd daemon password. Create it before setting up the mpd daemons. Use it to control access to the daemons by various IntelĀ® MPI Library users.
The file has a single line:
secretword=<mpd password>
or
MPD_SECRETWORD=<mpd password>
An arbitrary <mpd password> string only controls access to the mpd daemons by various cluster users. Do not use Linux* OS login passwords here.
Place the $HOME/.mpd.conf file on a network-mounted file system, or replicate this file so that it is accessible as $HOME/.mpd.conf on all nodes of the cluster.
When mpdboot is executed by some non-root <user>, this file should have user and ownership set to <user> and <<user>'s group> accordingly. The access permissions should be set to 600 mode (only user has read and write privileges).
This file has a list of node names which the mpdboot command uses to start mpd daemons.
Ensure that this file is accessible by the user who runs mpdboot on the node where the mpdboot command is actually invoked.
The format of the mpd.hosts file is a list of node names, one name per line. Blank lines and the portions of any lines that follow a # character are ignored.
