For performing simulations using GPU’s, it is necessary to have a knowledge of the GPU hardware of the system. To check for the available GPU’s using ANSYS Fluent, type the following command in the TUI/console para gpgpu show An example output of this command is shown below: CUDA visible GPUs on ComputerName CUDA runtime version 6000 Driver version 9020 Number of GPUs 1 0. Quadro P2000 6 SMs 1.607 GHz 4.29497 GBytes If the above command is executed in a Fluent session that already has GPU’s selected for performing the simulation, the output of the above command will contain “(*)” beside the names of the GPU’s that have been selected. An example output of this situation is shown below: CUDA visible GPUs on ComputerName CUDA runtime version 6000 Driver version 9020 Number of GPUs 1 0. Quadro P2000 (*) 6 SMs 1.607 GHz 4.29497 GBytes Keywords: ANSYS Fluent, GPU, GPGPU
