Pytorch prefetch

WebThe backward prefetch setting controls the timing of when the next FSDP unit’s parameters should be requested. By setting it to BACKWARD_PRE, the next FSDP’s unit params can begin to be requested and arrive sooner before the computation of the current unit starts. WebJan 20, 2024 · There is a way to prefetch data between cpu and gpu by cudaMemAdvise and cudaMemPrefetchAsync. I am wondering that is this has been intergrated in to dataloader. I found a flag prefetch_factor in dataloader constructor, not sure if it is the one. If not, how can I integrated it? cc @ssnl @VitalyFedyunin @ejguan
