The popularity of using Graphics Processors Units (GPU) to accelerate the simulations has generated interest in the ANSYS community because GPUs coupled with parallel processing can further reduce the simulation runtime significantly. ANSYS Mechanical version 13 has had support for GPU acceleration.  In this study we evaluate the acceleration with a single M2090 GPU on seven standard ANSYS Mechanical benchmarks.

Given a single fully populated C410X with 16 M2070 GPUs, the recommended solution for NAMD is an 8 node configuration shown below. On STMV, a standard large NAMD benchmark, it shows a 3.5X performance compared to an equivalent CPU only cluster.

It is recommended to use X5650 processors on compute nodes for NAMD
