Hi Giovanni!
When I start Namd on linux-alpha cluster with MPI + Marynet GM drivers
the queuing system provides me directory called "namd2.1" with following
files:
# ls -la namd2.1
drwx------ 2 makaveli ipmuran 4096 May 30 18:29 .
drwxr-xr-x 13 makaveli ipmuran 4096 Jun 4 18:52 ..
-rw------- 1 makaveli ipmuran 0 May 30 18:29 errors
-rw------- 1 makaveli ipmuran 496 Jun 4 12:11 .hosts
-rw------- 1 makaveli ipmuran 217006 Jun 4 18:52 manager.log
-rw------- 1 makaveli ipmuran 9613920 Jun 4 18:51 output
-rwx--x--x 1 makaveli ipmuran 2378 Jun 4 12:11 runmvs.bat
So my running Namd program automaticly resolves nodes from ".hosts"
and runs successfully. Perhaps in your case it will be the same
Cheers,
Alex
