AMBER: maximum number of processors

Date: Wed, 11 May 2005 23:53:44 -0400 (EDT)

Hi Amber users,

I normally run sander with 16 nodes (dual processor in each) and I know the
speed of the run. This time I tried using 32 nodes, but the speed seems just
the same as 16 node runs. The system I simulate is completely the same as
before. Is there a limit for the number of nodes that AMBER can use? Or is
there another point I cannot figure out?


PS: I use amber7 and all nodes are functioning well.
