Hi Chris, You should be able to run on MIC/Xeon Phi as these accelerators, when used in symmetric mode, behave just like a compute node. However, for two main reasons the performance will be quite bad: - no SIMD accelerated kernels for MIC; - no accelerator-specific parallelization implemented (asymmetric/"offload" mode).
Note that OpenMP alone won't help much. Both are work in progress (see redmine #1181 and #1187), but there is no target date for the availability of an efficient MIX/Phi-optimized GROMACS version. I personally hope that we will have something in form of preview release based on 4.6 (but probably not included) and if it works well enough, perhaps included in 5.0. Let me take the opportunity to say that if anybody is interested in contributing to the MIC acceleration (or other HPC, computing, or scientific aspects of GROMACS or MD in general), we are in the process of defining more or less independent projects for new contribution/collaboration: http://www.gromacs.org/Projects_available_for_new_contributors#Intel_MIC_support.3a.c2.a0implementing_asymmetric_offload_mechanism Cheers, -- Szilárd On Sat, Mar 9, 2013 at 2:43 AM, Christopher Neale < [email protected]> wrote: > Dear users: > > does anybody have any experience with gromacs on a cluster in which each > node is composed of 1 or 2 x86 processors plus an Intel Xeon Phi > coprocessor?
