[aspect-devel] mktemp failure

[Eric Heien]

From my initial work, it appears that the location specified by $TMPDIR is in fact not accessible from all processes during a run, which was causing the problem.  I've emailed TACC to confirm this.  Instead, for scripts run on Lonestar (and probably other XSEDE machines) we should export TMPDIR=$SCRATCH in the submission script - this appears to fix the problem.

In any case I will rewrite the output function to gracefully handle this.  Also, I will remove exception throwing from this function since in a separate thread they will be uncaught and potentially cause the program to hang (as was happening with me).
