I'm running Mini Collatz on my 7950 (need the hours), but the project is only sending me one WU at a time. My app_config is set up to run 4 WUs per GPU, I don't have a max_concurrent line, I've bumped up the project resource share, and I tried suspending all other projects and updating - still only getting one at a time. Meanwhile my laptop has a nice cache of Mini WUs for intel gpu. Any suggestions?
