Figure 9: Amber Performance on CPU and P100-PCIe
ANSYS Mechanical
ANSYS® Mechanical™ software is a comprehensive finite element analysis (FEA) tool for structural analysis,
including linear, nonlinear dynamic, hydrodynamic and explicit studies. It provides a complete set of
element behavior, material models and equation solvers for a wide range of mechanical design problems.
The finite element method is used to solve the partial differential equations which is a compute and
memory intensive task. Our testing focused on the Power Supply Module (V17cg-1) benchmark. This is a
medium sized job for iterative solvers and a good test for memory bandwidth. Figure 10 shows the
performance of ANSYS Mechanical on CPU and P100-PCIe. It is shown that within a node, 4 P100 is 3.8x
faster than dual CPUs. And with 4 nodes, 16 P100 is 2.3x faster than 8 CPUs. The figure also shows that
the performance scales well with more nodes. The speedup with 4 nodes is 2.8x compared to 1 node.
