I don't have a strong preference. I'm generally in favor of spending more computer time when it means less human time involved, but if you choose to sieve on the algebraic side then just create a new...

There's a typo in the line
lss : 0
Because of the extra space between lss and the colon, it wasn't recognized and sieving defaulted to the rational side. I recommend at this point to simply...

Thanks. I agree that copying those definitions isn't a good idea. I was hoping that it could be done using the documented public GMP interface relatively easily without loss of speed. Too much to ask...

Likely it will. While the RX 7900 XTX is overall a much faster card (a MI60 is based on the same architecture as the Radeon VII) the 1/16 FP64/FP32 ratio on the RX 7900 XTX slows it down for gpuOwl.

32GB MI60's are available for under $1000. But they are passively cooled so you'd have to deal with rigging a cooler for it.

A MI250 is really two MI210's in the same package. Since gpuOwl doesn't support multiple GPUs, a single run on a MI250 will run on one of them and give the same times as a MI210. You can just run two...

Also the MI250X (and MI250) are really two GPUs packaged together, like the nVidia K80. AMD hides this a bit in their marketing. So expect only half of that performance in a single gpuOwl run. And...
