@george : just for info I looked at my computer detail page on amicable, I don't think there is an equivalent info as the "cache" from einstein detail page for that same machine, it is between memory (RAM) and swap file size, there is nothing between these two on the amicable detail page... 

This leads me to think that it may be something attributable to Einstein GPU tasks not getting done in a reasonable time frame.  Again, I'm just guessing though.

Hi I decided to

Hi

I decided to have another try on O3 : I don't have anymore errors in the log as I used to, just a few warnings, but the behavior remains the same = almost 0 GPU usage during the execution time, it uses 1/3 of a CPU thread all the time (except 1 or 2 min at the beginning where it's closer to 1 CPU thread) and it takes 20 hours to complete, credited 10k. 

So it's definitively not worth the computation time, even if it is of any scientific interest (?) the performance is way too poor. 

Let's switch somewhere else, though the options for GPU crunch on a mac are very limited nowadays :/
