I've managed to run my simulation in parallel on a couple of G5 mac computers 
but i've noticed that my performance does not increase after three nodes. I am 
guessing the possible reason for this to be:
1. simulation is bottlenecked by the ethernet connection
2. my molecule is not configured properly to take advantage of mutiple sys... 
i have my cutoff  set to a large number(essentially no cutoff) but if i change 
it to smaller number with switching on the simulation seems to be distributed 
between the systems better. 
3. patch size...i think this is related to reason #2. because number of 
patches namd creates seems to be dependent of the conf file and simulation 
speed seems to be dependent on the number of patches.
could anyone provide some insight into  my situation. 
Cheers
