	But it is not recognized to run OpenCL GPUGRID tasks in other projects works without problem,the same in Ubuntu 14.10 in Windows 8.1 POEM for example. Greetings. Because our application is for AMD GPUs. Matt

	Because our application is for AMD GPUs. Matt Hello: Thank you, if you already know and understand. I think it would be good for the project, as in others, the tasks were for AMD OpenCL GPU and NVIDIA since both support it. Greetings.

	I think it would be good for the project, as in others, the tasks were for AMD OpenCL GPU and NVIDIA since both support it. Greetings. Quite the opposite. Allowing that application to run on NVIDIA GPUs will mean it will compete against our primary application for resources, with the result that our overall capacity will be reduced. Matt

Matt Factoring in recent GROMACS application additions: OpenMP SSE/AVX CPU/AMD CL HSA - will Intel's Iris OpenCL iGPU (Haswell/Broadwell/Skylake) compute 1TeraSPFLOPS/256!G/DP) become a future GPUGRID resource? ?? GPUGRID Resource Efficiency/(ns/day)(hour/ns) performance > CUDA > ?Intel? HSA > CPU only > OPENCL HSA ?? App mdrun-917/VERSION 5.1-dev utilizing AMD GPU (Tahiti/Hawaii) OpenCL 50~ns/day. SSE2 CPU computes ~1.5 to 4.0~ns. for [1] thread (4ns a thread = 256AVXcode) Will CPUMD only paths reappear before the Summer season? GM204 GPU 6.5CUDA ACEMD task (70katoms/5e7step) achieves 300ns/day. 100ns/day for the resourceful GTX750 with a GTX960 producing 200~. GK107 provides 40ns/day. (ns. Variation with interchangeable Total atom/Step length) Looking at the methods: is [1] MDrun 917 task - step length 200k (400.0 ps.) 12-25x smaller than prior 2.5/5.0e7 (5k ps.) CPUMD?

	Intel iGPUs - probably not, they aren't very well-suited for compute CPUMD - no, that's unlikely to make a re-appearance. The performance simply wasn't good enough. We're going in the direction of a hybrid CPU-GPU application for AMD GPUs. Matt
