A weekly summary of news and notes for MLC@Home
This week saw the rollout of the v9.5x updated series of clients in preparation for Dataset 3 WUs. Unfortunately the rollout wasn't as smooth as we planned, so most of this week was spent on engineering issues with the client and not on the science. That should change this week, however!
News:
- MLDS v.95x clients released (see announcement for changelog)
There were initial issues server-side and the updated windows client, so it was released later than the linux clients. Then multiple issues were uncovered with the new build process not including all needed DLLs and only targeting Windows 10. While some hosts are still reporting failures, most windows issues should be cleared up with the newly released v9.55 app. If you have further issues, please post to the discussion thread
New Linux clients also experienced some issues. While some users are reporting a nice speedup over v9.20, others have WUs exiting with "signal 4" (illegal instruction) with the new build. This is related to the old version of OpenBLAS bundled with the binary mis-detecting CPU features on some hosts. We're working on a fix, but in the meantime, a workaround is available as detailed in this discussion.
We're hoping to get dataset 3 WUs moving this week as these issues with the new client app are worked out.
Progress on datasets 1 and 2 continues unabated
No updates on the new server
