[LA-SiGMA-gpu] Fwd: namd-l: Nvidia GPUs

[Jian Tao]

Hi Tom,

A GTX cluster could be very cost-effective for some applications.
I heard from a collaborator from the Poznan supercomputing and networking center (PSNC) in Poland that they did build a GTX cluster a couple years ago. I could check to see how things are working.

Some of us at CCT are collaborating with researchers from the Charm++ group in other projects. We know that their team is helping the NAMD group to port and optimize NAMD on GPUs. There have been a lot of work on GPUs lately though a lot of their own efforts are on high-end GPU cards mainly because they are actively involved in the Blue Waters project.

As you may have heard, LSU HPC will very soon make available a half million dollar Kepler cluster, Shelob. The LA-SiGMA project is one of the main science drivers of the Shelob proposal. You and other LA-SiGMA teams who are doing GPU related research shall have access to the system.
IMHO, effectively sharing such resources is economically better than hosting a personal cluster if cost is one of the major considerations. While the LSU GPU team might not help you much on NAMD itself, we will work together with LSU HPC to at least help your team to get started on the system once it is ready.

Regards,
Jian
