By default, the 'Tasks' column for 'qstat -a' is three characters wide.  It's
not that uncommon for a modern cluster to consist of at least 1000 cores.  In
that case, the value is truncated such that only the first three digits are
shown for large jobs.

If you define "TXT" when you compile, then the column gets set to 5 characters
wide.  This works great for up to 99,999 cores, but some systems using TORQUE
have over 100,000 cores.

For the short term, the easiest "fix" would be to make the default 4 characters
and TXT 6 characters.
