Since:
- GPU tasks won't run on Intel GPUs
- CPU tasks have become almost impossible to complete within the 72 hour window

For those of us who have Intel GPUs, what are the pros / cons of opening up 10^21 exclusively for CPU tasks, while 10^20 is finished by those who run GPU?

I'd like to make a contribution to Amicable Numbers, but currently I can't run 10^20 CPU or GPU tasks.

Additionally, this would be a good test of the 10^21 CPU tasks.

while 10^20 is finished by those who run GPU?

The search for 10^20 is currently 88.0658% complete. Almost all of the work is being done by the CPU. It takes over an hour to run one it on a 1070 TI
