Upcoming GPU Zeta core

post #1 of 4
Thread Starter 
I was checking change log for v7.3.3 and found

Added new -gpu-vendor core option for upcoming Zeta core.

And I tried to find more info about it. Some info in FAH papers

108. OpenMM 4: A Reusable, Extensible, Hardware Independent Library for High Performance Molecular Simulation.

Eastman P, Friedrichs MS, Chodera JD, Radmer RJ, Bruns CM, Ku JP, Beauchamp KA, Lane TJ, Wang LP, Shukla D, Tye T, Houston M, Stich T, Klein C, Shirts MR, Pande VS.

Journal of Chemical Theory and Computation (Jan 2013)

SUMMARY. This paper discusses OpenMM 4, powerful and adaptable library for molecular dynamics, is one of the key components behind our current GPU FahCores. A more recent release, OpenMM 5, powers the upcoming FahCore 17 (Zeta). We are looking forward to OpenMM 5.1, which should be a big release from the user's perspective and offers a lot of exciting scientific features.

ABSTRACT. OpenMM is a software toolkit for performing molecular simulations on a range of high performance computing architectures. It is based on a layered architecture: the lower layers function as a reusable library that can be invoked by any application, while the upper layers form a complete environment for running molecular simulations. The library API hides all hardware-specific dependencies and optimizations from the users and developers of simulation programs: they can be run without modification on any hardware on which the API has been implemented. The current implementations of OpenMM include support for graphics processing units using the OpenCL and CUDA frameworks. In addition, OpenMM was designed to be extensible, so new hardware architectures can be accommodated and new functionality (e.g., energy terms and integrators) can be easily added.

When we should see this core and is it the one that work with Linux and good for AMD?

No one calls it that. In fact I've never heard of it called that and I am running it right now on my GPU. It should be much better for AMD cards. For reference a 7970 does 1:10 TPF and a 570 does 1:25 TPF, both cards at stock. Thats a smaller WU than what will be production and thats a slow debug version of core 17.

If you want it in Linux, make sure to vote in proteneer's Linux GPU thread.

I'll be sure to let everyone here know when it moves to beta. Search for core 17 on FF and you'll get a ton more hits.

And v7.2.9 currently does support that option, maybe FAHControl doesn't but I guess it's needed since core 17 is for AMD and Nvidia.

It's currently in internal testing.

Thanks for info,
I'm interesting more for AMD that linux as I run 5870 for TC and see that I do not have much affect on team performance feel pointless and frustrating.

A 5870 ran at 3min TPF on the same WU at stock 850MHz. still better than a 6870 at 3:37 TPF.

I know what you mean. I'm also in the AMD cat and I'd like to contribute more than 223k in a month...
