It's just that the work that comes in is streamlined by the drivers to make the scheduler's job easier. Not that it would matter anyway, since the basic requirement to support asynchronous compute ...

WebOct 18, 2024 · The synchronization framework explicitly describes dependencies between different asynchronous operations in the Android graphics system. The framework provides an API that enables components to indicate when buffers are released. ... EGL_ANDROID_wait_sync allows GPU-side stalls rather than CPU-side, making the … WebDec 20, 2016 · I am pretty sure that the asynchronous APIs at the lower DirectX 11 level can perform a read with no visible CPU or GPU waiting at all. This works because the call initiates the transfer of data from the GPU and then the callback is not invoked until the memory transfer is complete.

WebGPU operations are asynchronous by default to enable a larger number of computations to be performed in parallel. Asynchronous operations are generally invisible to the user because PyTorch automatically synchronizes data copied between CPU and GPU or GPU and GPU. ... Another instance to be mindful of whether to use async or sync operations …
