# node (2 cores, 1 quarter memory, 1 quarter scratch disk).
# The methane2.input deck in this directory is configured
# to work with these resources, although this methane
# computation is really too small to make use of even
# one fourth of a node. To increase the resources used
# (cpus memory, or disk) change the '-l select' line here
# and the parameter values at the head of the Gaussian
# input deck.
