I've got a question about load balancing.

I'm working with NAMD 2.6b1 on a Rocks linux cluster. I've been
benchmarking an input set that contains ~58000 atoms. It's not
scaling very well:

Procs sec/timestep
1 2.5
8 .75
16 .67

I ran another input set ap0a1, which I found on the NAMD site, and for
which there are published benchmarks showing good scaling, and saw:

Procs sec/timestep
