Using ANSYS high performance computing options

You can use options in the Solver Parameters dialog box to set high performance computing options for ANSYS analyses. You can:

• Control the use of shared-memory parallel processors.

• Use GPU acceleration.

Shared-memory parallel processing

In ANSYS, you can shared-memory processing to solve an ANSYS solution across multiple processors on a single machine. Running ANSYS on a shared memory architecture is one of the easiest ways to improve the performance of ANSYS.

In Pre/Post, you can select the Use Shared-Memory Parallel option and then specify the number of processors (-np) that you want to use on a single machine.

For more information, see Using Shared-Memory ANSYS in the ANSYS Advanced Analysis Techniques Guide.

GPU acceleration

ANSYS 13 and higher supports the use of a graphics processing unit (GPU) to increase computing capacity. The ANSYS GPU accelerator works by off-loading some of the most numeric-intensive algorithms from the CPU onto the GPU. Currently, ANSYS only supports the NVIDIA Tesla GPU for use when accelerating ANSYS solutions.

In Pre/Post, you can select the Use GPU Accelerator option to use the GPU accelerator capability.
