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 (as

No idea. It was not a development target for 4.6, and there are no explicit plans for considering Xeon Phi at this time. It would be interesting to hear whether people can get benefit from them from our existing OpenMP parallelism support for (particularly) PME + Verlet kernels. Roughly speaking,

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? Can gromacs make use of the xeon phi coprocessor? If not, does anybody know if that is in the pipeline? Thank you, Chris. -- gmx-us
