Thank you very much this worked perfectly. Here are the details
for the list archive and anyone who is interested.

Downloaded the source and compiled on our clustermatic 5 AMD64 cluster with:
./build charm++ net-linux-amd64 clustermatic

Our cluster nodes have 2 CPUs so se used this to run:
./charmrun ++skipmaster ++nodelist $nodelistfile ++p $num_procs namd2 alanin
Not sure that the ++p option makes a difference but it seem to work for us.

we have an NFS shared file system to run this on so our nodelist file looks like this.

group main
host 26
host 28
host 29

I will try running with out NFS with the "-1" host later.

Thank you again for the help
