A weekly summary of news and notes for MLC@Home
If you're in the US, and you haven't already taken advantage of early voting, please VOTE tomorrow.
Summary GPU week(s), part 2. The downsides of giving weekly updates is sometimes you don't have a lot to report. Sadly most of this week was lost attempting to debug a strange crash related solely to the client when compiled for Linux/CUDA. It turns out it has nothing to do with our code, its a strange interaction between the threading library used in the pre-compiled pytorch libraries, and the BOINC library. It took several days for us to realize it wasn't our code causing the issue, now it'll take a few more to find a solution, which will likely require a custom-compiled pytorch, which will take a few more days to debug.
GPU speedups are worth it, but please bear with us as we work through these issues in the testing queue, and keep churning away on the main research queue!
News:
- We expect to have most CUDA issues ironed out and have them in general (non-beta) use by lastnext week. ROCm support would be next, but it is a lower priority.
Datasets 1,2 and 3 continue crunching away. GREAT progress so far!
We will back off on the WU FLOPS estimates for any newly issues WUs starting this week, this should solve the overestimation problems with time.
Spent a little time working on DS4 and the DS3 paper, but GPU debugging again took up the majority of free time.
