[Swift-devel] problem with coasters on pbs provider (on pads)

[wilde at mcs.anl.gov]

Glen, I've worked on this problem in the past; I will look to see if I have a fix in one of my test versions. In the meantime, say workerspernode=1, and I *think* it will correctly run single-node jobs and PBS will place up to 8 of these per node.
