[gmx-users] Re: [gmx-users]mdrun crashed on upgraded Dual1.0GMac OS X

[Taeho Kim]

Hi
Sorry for my unclairty on the problem. Let me make it clear.
Since there is no benefit for using two machines for Gromacs, I run Gromacs on a Single dual Mac. The problem is arising from a SINGLE dual-processor Mac, not a two-node Mac cluster. I am  testing out Gromacs on Macs that were upgraded from single processor machines to dual-processor machines using PowerLogix dual-CPU upgrade boards.

Anyway, I'll keep in mind your comment regarding "--with-rpi=tcp" . (By the way, like others I had disappointed results from two machines with "mpirun -lamd -np 2 mdrun ~ "). I'll test out the flag as well. 

Thanks,
Taeho
