Default proth 2.0 use

Anyone from CRUS using proth 2.0?

There was a brief discussion here. I'd like to know how well it works for our project's purposes.

proth20 can only be used for k*2^n+1. In other words b = 2 and c = +1. Hopefully Yves will extend that to other bases and c = -1 in the near future.

My experience is that it is slower than pfgw, but I haven't run it with many different values of n to see how it scales as n increases.

Do both pfgw and proth20 run on Nvidia GPUs?

It has no sense to compare PFGW and Proth: one is run under GPU and another is run under CPU.
Proth 2.0 has very nice performance

Table of limits ( when program go to next step)


Red is exponent on k*2^n+1

2^17 [ 688,094 - 1,376,221]
2^18 [ 1,376,222 - 2,752,477] PPSE (1.5M)
2^19 [ 2,752,478 - 5,504,989] PPS (2.8M)
2^20 [ 5,504,990 - 10,485,716] DIV (5.5M)
2^21 [10,485,717 - 20,971,486] ESP (14.1M), 321 (15.5M), Cullen (17.7M)
2^22 [20,971,487 - 39,845,845] PSP (22.1M), SOB (32.5M)
2^23 [39,845,846 - 79,691,743]
2^24 [79,691,744 - 99,999,999]

How does the performance compare per watt on typical hardware?
