GPU Settings Rollout

tyFlow’s various solvers may utilize GPU compute cores, depending on your simulation settings. This rollout allows you to control which GPU will be used for computations.

OpenCL GPU

Use the listbox to select which GPU should be used for OpenCL computations.

CUDA GPU

Use the listbox to select which GPU should be used for CUDA computations.

Only NVidia GPUs with up-to-date drivers can be used for CUDA computations.

  • Compatibility Mode: enabling this mode will substitute faster cuBlas functions with simpler matrix multiplication kernels. The simpler kernels are slower, but may prevent CUDA crashes on certain systems where mysterious cuBlas crashes have been occurring. Hopefully a solution to the crashing will eventually be discovered and this mode will no longer be required. Until then, it exists as an option for users running into CUDA issues.

If CUDA crashed, try enabling this mode. You will need to restart 3ds Max after enabling this mode in order for it to take effect.
