ANSYS HPC Packs enable acceleration using graphical processing units (GPUs) when used in conjunction with ANSYS applications that support GPU computing. ANSYS Mechanical offers GPU acceleration for direct sparse and PCG/JCG iterative solvers in both shared- and distributed-memory modes.
The latest version of ANSYS software extends this to support for multiple GPUs per machine, resulting in an increase in scalable performance versus use of a single GPU. In addition, large models that exceeded the memory capacity of a single GPU (and disallowed its use) fit with multi-GPU memory and benefit from acceleration.
ANSYS Mechanical customers can interchangeably use CPU cores and multiple GPUs — on a workstation or on a GPU-enabled server — to accelerate most simulation workloads.
With ANSYS Fluent, view factors and ray-tracing (radiation) on GPUs are fully supported features, leading to dramatic reduction in computational time for these steps in the simulation. Users can write UDFs to take advantage of GPUs.
