Reuti, Once again, thanks for the helpful feedback. One of my users requesting this behavior found a discussion on on this arrangement on the SGE mailing list dating back to 2002. I plan to do some googling for details today. I may have some SGE specific questions about this, which I'll post to the SGE list if necessary. -- Prentice _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
