Time is as time does. If you contribute by processing 100 GPU WUs at 30 seconds each then you have done 50 minutes processing.

To say that if you had done them on the CPU it would have taken 150 hours is ridiculous.

If Open Pandemics were GPU only i would do much more MCM work units.My proposal would increase OPNG work units higher then it is now but not as high as it was during the stress test based on availability of the work units

I also agree that it would be great if we did most of the work on the GPUs. AFAIK/IIRC, the current GPU and CPU work units are very similar with the main difference being that GPU's pack much, much more work. In the future, the researchers hope to use the GPUs for the more complex molecules which would take much more time on CPUs than they would on GPUs.

CPU isn't going away but it would certainly be nice if, at some point, GPU's represented the bulk of the work being in OPNG and that the freed up CPU power went to other projects.

Edit: There is a post from one of the researchers that describes the differences in CPU vs GPU . It's a bit old now (almost 1 year old) but I'm guessing it's still valid.

It would be a shame if WCG would continue to push OPN CPU workunits if:
- OPN and OPNG workunits are fundamentally doing exactly the same (same functionality)
- The performance of OPNG is X times better than OPN (==> that's a fact)

I don't know if the first condition is true, but if it is then it would be a waste of resources to do OPN works with CPU's. There are other projects hunting for CPU power which cannot be converted to GPU. It's a matter of using the limited resources in the most effective way...

Considering the limited resources for the large computational needs of WCG and BOINC projects, and the fact that GPUs run the work far more efficiently, I think that's a stronger point than "choice" or "being able to contribute". If there's something that does the work a lot faster and using less resources, why choose the slower, less efficient option? Still, it's a non-issue since CPU work isn't going away. Just my opinion.

That said however, everyone can get a free GPU at Google Colab, even if only for 12 hours every couple of days. I've seen it run a Nvidia K80, a Nvidia P4 (not recently, though), a Nvidia T4 and a Nvidia P100. They do good work, even if just the K80. I run it every now and then instead of my RX 550 or my laptop GPU.
