Dear users:
I received this error message that gromacs 4.5.3 does not allow me to
run on 34 cores. I suggest that this gets put in as a warning (so that
I can avoid it if I choose and actually run on 34 cores).
A run on 32 cores -npme -1 choose to use 24 particle-particle nodes
and 8 PME nodes. I therefore selected 34 cores and -nmpe 10. I don't
see how the large prime factor is relevant when -nmpme is not equal to
zero.
The error message was:
Fatal error:
The number of nodes you selected (34) contains a large prime factor
17. In most cases this will lead to bad performance. Choose a number
with smaller prime factors or set the decomposition (option -dd)
manually.
