I have made one significant change in the code I plan to commit for NEMS
Trac ticket #104. In my original message I said the forecast would be
shut down if a run of the NMM-B was requesting only one compute task.
Instead I've included the modifications so that global runs can now
execute with a single compute task. Regional runs can already execute
successfully with one compute task. Below is the latest list of file
modifications in trunk_update at the same locations as given in the
earlier message. The default netCDF modules on each machine may be
used. I will initiate regtests on tide sometime tomorrow after the
firewall work is complete.
