Hi,
We have bought new cluster with Myrinet, and I have install GROMACS
3.3.2 and openmpi 1.3.3. Now, in order to run my gromacs I am using
'mpirun -np 32 mdrun_mpi -np 32 ...' (each node has 8 CPUs). my
question is, are there any flags used with openmpi which will make it
use Myrinet better? I am aware to the options '--mca btl sm,self,mx'
and '--mca btl self,sm --mca mtl mx --mca pml cm' but some benchmarks
I did show no improvement, on the contrary. So I will be happy to try
some ideas in order to utilize the system better.
Now, I am quite sure that there is an answer to my question somewhere
in the mailing list, but I can't check it 'cause I can search it.
Someone knows how I can do it?
All the Best,
Itamar
