# The general format is that "local 0" (required) implies creation of a master.
|
|
# Otherwise there is one line per slave.
|
|
# The first field is the hostname or localhost (in a form valid for "rsh")
|
|
# If you prefer ssh over rsh, then (e.g. in csh): setenv RSH ssh
|
|
# The second field, 1, is obligatory.
|
|
# The third field is an absolute or relative pathname (e.g.: ./XXX or ../XXX)
|
|
# of the binary. A relative pathname is appended to path of the binary
|
|
# on master. The slave process will execute in the same directory
|
|
# as the current working directory of the master, if possible.
|
|
# Otherwise, the slave will execute in the home directory.
|
|
# If the third field is `-', then the command line (including arguments)
|
|
# for that slave will be the same as on the master.
|
|
# Any additional fields (fourth and beyond) are appended to the
|
|
# command line for that slave only.
|
|
# Note that '>slave1.out' works, redirecting standard output. However,
|
|
# the output file, slave1.out, will be placed in the home directory.
|
|
# Currently, `localhost' implies the Bourne shell, and any other
|
|
# name implies the default user shell for that machine.
|
|
# By default, standard output and error are sent to user tty (a la rsh).
|
|
#
|
|
# The format is inherited from MPICH, which grew from P4.

#=========================================================================
|
|
#EXAMPLE:
|
|
# # Master process
|
|
# local 0
|
|
# # One slave process on local computer, using same binary and same arguments
|
|
# localhost 1 -
|
|
# # One remote slave process, with absolute path to binary and no arguments
|
|
# regulus.ccs.neu.edu 1 /ccs/tmp/gene/a.out
|
|
# # One slave using alpha architecture,
|
|
# # with path of alpha binary relative to binary of this master process.
|
|
# # Output placed in slave-alpha-1.out in user's home directory.
|
|
# alpha.ccs.neu.edu 1 ../alpha/a.out > slave-alpha-1.out
|
|
|
|
#=========================================================================
|
|
#IF YOU HAVE PROBLEMS:
|
|
# MPINU uses "rsh" to start a slave process. Diagnose it via:
|
|
# rsh REMOTE_SLAVE_HOST hostname
|
|
# If it doesn't work or if it asks you for a password, try:
|
|
# 1. Add a .rhosts file on the remote host and specify your local host.
|
|
# 2. Sometimes adding .localhost to your .rhosts helps.
|
|
# 3. Specify an alternative to "rsh" in your shell. For example:
|
|
# RSH=ssh; export RSH # in Bourne shell, bash, etc.
|
|
# setenv RSH ssh # in csh, tcsh, etc.
|
|
# 4. If you use "ssh", you may also need to copy keys to allow
|
|
# login to the remote host without a password.
|
|
# It's also possible that mpinu guessed badly the hostname of your local host.
|
|
# If you suspect this, on the master try (in csh, tcsh):
|
|
# setenv CALLBACK_HOST LOCAL_MASTER_HOST
|
|
# where LOCAL_MASTER_HOST is the correct hostname of the local master.
