Dear All,

I have until now used the parallel version of pmemd employng a number of
processor that was a power of two (In the older version of sander there was
this restrictions and I went on like this). Now I'm using a cluster with 12
cpus on each node, and it would be useful for me to use a number of
processors multiple of 12. Is the restriction of the power of 2 still valid,
or anyway does it still assures better performance, or can I safely use an
arbitrary number of cpu?

Thank you in advance
