Webmilliseconds [2,3]. If a GPU switches to a DNN model (e.g., ResNet) that has not been preloaded onto the GPU,it can take multiple seconds before serving the ﬁrst inference request, even with state-of-the-art tricks like CUDA uniﬁed mem-ory [4] (§6). In contrast, CPU applications can be switched in milliseconds or even microseconds [5]. 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.
