通过wait_for_async_insert 设置,您可以配置是否希望在数据被插入缓冲区后(wait_for_async_insert=0)或默认情况下,在数据从缓冲区刷新后写入部分之后(wait_for_async_insert=1)立即返回插入语句的确认。设置 wait_for_async_insert ... DescribeParameters How long the coordinator should wait for seq or ind...
This PR changes how we insert async wait expressions on async operations that have a commit-wait flavor (wgmma, TMA store). In the past, we always just insert a commit; wait 0; right after the async operation itself in the ReadAfterWriteSyncs pass, which means, we just force making the...
Previously, we insert mbarrier waits in the circular buffering pass like below: For each TMA that loads the circular buffered tensor, we insert a mbarrier wait right after that TMA expression waiting for the completion of the previous iteration. This is sub-optimal because, for example, if a...
Can we barrier async instead of lock as shown below. It seems that this code is taking a bad idea, using a Dispatch queue as a lock for a tiny critical section, and then applying an additional bad idea on top of that, concurrent queues. Share and Enjoy— Quinn “The Eskimo!” @ Dev...
