If 2.253G were supported in some proofcapable gpuowl version, its PRP/proof would take ~ 2. years on a Radeon VII. From a 268 msec/iteration timing on Mlucas in 128M fft, on Ubuntu/WSL/Win10, using 24 threads on all 24 real cores of a dual Xeon e52697v2 system, it would take ~19.1 years there. I think one could do quite a bit better than that in Mlucas on native Linux, & perhaps employing more threads and/or different hardware, but it is still likely to take at least several years to run on any CPUs I have. And currently, proof generation is not released in Mlucas, and Cert capability is not available, in any known software for such a high exponent, so 2 full PRP runs would be necessary. Proof generation on Mlucas may become available before the P1 stages complete, or shortly after. That would leave unresolved how to perform a cert for an exponent nearly double the maximum now supported in mprime/prime95. Last fiddled with by kriesel on 20220413 at 16:38

Combining the two small lists, Predict Mxx lacking completed DC, and dubious claims lacking completed DC, but within range of feasible P1 factoring, yields 5 exponents (for now). Current status of each follows:

Combined list update: Predict Mxx lacking completed DC, and dubious claims lacking completed DC, but within range of feasible P1 factoring, yields 3 uncompleted exponents (for now). Current status of each follows:

A PRP with proof generation would take ~3 weeks in Gpuowl on a Radeon VII. ShenTianYing reported a poached composite result 20220901, apparently without proof generation. Kriesel is running DC PRP with proof generation.
