Hello guys
Are you foolish or what?

Not as foolish as you for running two at time.
Per Task runtime doesn't matter- the number per hour is what matters.

On my RTX 2060 & RTX 2060 Super the GPU load is around 75% to 80% for these Tasks.
Given that the GPU load is over 50%, and it requires about 1.3 CPU cores to support one Task, even if you give them 3 CPU cores to support 2 GPU Tasks when running two at a time, and the fact that the application has not been optimised much (if at all) as shown by the frequent dips in the GPU load & less frequent but very regular large dips in GPU load, it doesn't make much sense to run 2 at a time.

Run one at a time & see how it goes.


As for the Credit per Task- it's Alpha work, things will change as they progress. At least for the last batch the Credit per Task was much more consistent than the earlier batches & applications.
And as for their Runtime- while they take longer than the last batch, they are still taking less time than the first batch i was able to process on the GPU.
