Hi All

I have a problem with runing NAMD on a cluster (8 biprocs) MP2200 (amd athlon)
1800 MHz. I set up the cluster using NPACI Rocks cluster distribution 3.2

now charmrun runs on the master biproc, and any other biproc if I use a single
unit;

NAMD_2.5_Linux-i686-TCP/charmrun +p 2 ..... ok

now if I use more than a single tower (3 procs and above) I get the following
error message.
