DESCRIPTION

wwlist shows a current list of configured nodes, in several different formats (eg. LAM/MPI machine file, PVM machine file, list of nodes in READY state, etc...).

OPTIONS

-r --ready

Only show nodes that are ready (shortcut for -s ready)

-i --idle

Only show nodes that have no user processes running and less then 5% cpu utilization.

-d --down

Only show nodes that are in the _NOT_ READY state

-m --mpi

-l --lam

-s --status

Only show nodes matching a particular status: (ready, down, unavailable, unknown)

-q --quiet

-h --help

ENVIORNMENT

NODES

The NODES enviornment variable will limit which nodes are displayed. It can be used either as a list of nodes, seperated by commas, or pointed to a file which contains a list of node names. You can set it with the following syntax:

for bash:

export NODES=node0000,node0001,node0010,node0011

for (t)csh:

setenv NODES /path/to/node/list/file
