mboehm7 opened a new pull request #1028: URL: https://github.com/apache/systemds/pull/1028
This patch fixes two major issues of request interference from multiple coordinator threads. First, we now properly maintain separate execution context at the federated site for different request streams from parfor workers which otherwise could interfer (e.g., on rmvar instructions for shared input variables) Second, even within a stream federated requests (e.g., execute and cleanup) could out output each other if there are no data dependencies or synchronization between them. We now added barriers for federated requests wherever this was necessary. Last, this patch also fixes unnecessary warning messages of the parfor optimizer, specifically in a setting with forced singlenode execution. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
