It’s a no-op if this argument is a negative integer or None. WebJul 26, 2011 · The best practice would be to create one CUDA context per device. By default, that CUDA context can be accessed only from the CPU thread that created it. If you want to access the CUDA context from other threads, call cuCtxPopCurrent () to pop it from the thread that created it.

WebReduced GPU context switching Without MPS, when processes share the GPU their scheduling resources must be swapped on and off the GPU. The MPS server shares one set of scheduling resources between all of its clients, eliminating the overhead of swapping when the GPU is scheduling between those clients. Identifying Candidate applications WebSep 18, 2024 · CUDA provides streams that allow the user to asynchronously launch a sequence of kernels and memcpys that must execute in order. The GPU automatically waits for the prior item in a stream to complete before starting the next one. The GPU may need to finish higher priority kernels before it can start a lower priority kernel.

WebOct 6, 2012 · 1 Answer Sorted by: 1 Context switch introduces a small hit, but in your case it would be pretty negligible, so you can safely switch between compute and render pipeline several times in the same frame without having to worry about it.
