Dear Szilárd,
now 64 cores machines are available, for instance, using Xeons E7-8837.
Do you have any idea about which combination will give more performance?
I mean, 64 CPU cores or 16-32 CPU cores + 4 C2075 or similar. The limit
of 4 GPUs is imposed by the MB of the machine I have in mind.
Thanks for the information.
Sincerely,
Dr. Rafael R. Pappalardo

Hi Andrzej,
One more question: will a ratio of gpu/cpu units and cores be of
importance
in next gromacs releases ? at the moment the code uses one core per
gpu
unit, wright ? When the code is gpu parallel how can this change ?
Yes, it will. We use both CPU & GPU and load balance between them.
For
optimal performance you'll want up to 4-8 cores/GPU, but ultimately
it
depends on the performance of each.
