Resource Manager’s user
community, in cooperation with Cluster
Resources, contributed
several fixes in the last month to create TORQUE 1.2.0p5.
One
important fix stops the problem of qstat hanging while pbs_server is
waiting for an update from an offline MOM. The problem occurred when
a MOM in the “down, job-exclusive” state was marked offline
using the “pbsnodes -o” command.
A
patch submitted by the University of Maine fixes a communication
error during job cancellation. When Cluster Resources tested the
patch, they found it increased the performance of qdel in certain
circumstances.
On
behalf of the user community we would also like to thank all those
not mentioned above who helped find and fix problems and test new
patches. To learn more about TORQUE visit:
