Re: [gmx-users] AMD GPUs
Hi, The first Gromac 5.1 beta release is scheduled for the second half of January, and probably the OpenCL port will be in that. People keen to use the proper version when it is released will be extremely welcome testing that it works well on their hardware and simulation settings. Pending testing of all the different changes, the real release of 5.1 will likely be some time in Q1 2015. We haven't seen half the code people were planning to submit before the beta deadline, so maybe it will go very smoothly because there's not much to test ;-) Mark On Fri, Dec 19, 2014 at 2:14 PM, wrote: > Any estimate when this release is to be expected? > > > > Quoting Szilárd Páll : > > I was referring to the OpenCL port.

Re: [gmx-users] AMD GPUs
Any estimate when this release is to be expected? Quoting Szilárd Páll : I was referring to the OpenCL port. We are working with the Streamcomputing guys on the OpenCL port, the code is in review at the moment. We expect to have OpenCL for AMD and NVIDIA (for demonstration purposes only) support in the next release.

Re: [gmx-users] AMD GPUs
How about the open cl port of gromacs? http://streamcomputing.eu/blog/2014-11-01/ported-gromacs-cuda-opencl/ might have to check the list of bugs of 5.0 though.

[gmx-users] AMD GPUs
Hi, Please don't hijack other discussion threads! AMD GPUs will be supported in the next release, people did not use them before because they were not supported. Regarding performance, I only know the results of some early benchmarks in which the fastest card used was an R9 290 and ran about as fast as as GTX 780. Based on this expect that even the R9 290X will be a lot slower than a GTX 980, but it would be great if people on the list could try.
