Again. I'm forced to use old LLR on this number.

And I found out that it works at the same speed than new LLR.

Using IBDWT : Mersenne fftlen = 57344, Proth fftlen = 114688, Used fftlen = 65536

3*2^998975-1 is not prime. Res64: 7EE98F75BA3D8F97 Time : 2529.931 sec.

This was run with the new Windoze LLR on a P4 @ 2.53GHz with no problems. Did you use linux? Was it an Athlon? If neccessary I can repeat the test on an Athlon under Mandrake 9.2.

I ran the number on a Celeron under Windoze 98 SE, while Prime95 was running in background. Both programs were set with priority 8.

Jean Penn announced a revised version of LLR fixing the Res64=0 bug described above and some others. Proth mode initialization was buggy too, and he calls it "more serious" than the Res64 bug. I wonder does it mean that some primes could have been missed and that we have to re-run our tests or not?
