Ilia Cherniavskii 1149b9bbb5 Polling async net executor ... Summary: Implementation of polling async net executor. Notes: - New net executor async_polling - schedules CPU and GPU ops asynchronously, uses single polling thread - Events: update to Caffe2 events to support async CPU events, adding new methods: Query() - non-blocking checking of event states: INITIALIZED -> RECORDED -> SUCCESS/FAILED ErrorMessage() - when operation runs asynchronously and fails calling this on event will give error message - Tasks: using existing DAGNet's algorithm to compute CPU and GPU chains, a separate task for each chain - Polling: using single thread to query state of events - for CPU tasks atomically queries task state, for GPU task - uses cudaEventQuery; using Event - Scheduling of CPU ops: using global thread pools - Scheduling of GPU ops: using GPU thread pool per GPU device Reviewed By: dzhulgakov Differential Revision: D5985110 fbshipit-source-id: a9de7fcbb71d046a3aa1b573072b89a65dfeee8c		2017-11-03 07:27:44 -07:00
