In fairness to Mike Humphrey and his team at Altair (who now own PBS,
and are up the street from me), PBS is not designed for very high
throughput situations.  It seems to work reasonably well for low volume
long runs.  

LSF and to a degree SGE are designed for HTC (High Throughput
Computing).  This is Platform Computing's lifeblood, and IMO they do a
great job of it.  I am impressed with SGE as well, though I am still
working through some minor rough areas with it.
