Nice!!! A new k=8 prime!!!

Ian and I have completed S493 to n=200K; no primes were found for n=100K-200K; 5 k's still remain; base released.

SR383 is progressing. Slow because I got some possible hardware errors when using latest version of LLR, so I got YOYO to sieve even deeper. After 1 months of testing at different FFT lengths using PG and getting only valid primality results, I´ve began testing a week ago using P95s PRP testing. This means that following depth is reached:

S383 n=204220 (Progressing about 5K n per week)
R383 n=215600 (Progressing about 15K n per week)

Continuing testing. Thanks to benchmarks (thanks Pepi) in P95, I´ve now loaded all tests on the Haswell and all tests on the Xeon wich fits the L3 cache and therefor is running most efficient using 1 core per test. Next up, I´ll create workfiles that contains all tests that is most productive running on 2 cores per test.

Take care

I was gone for an long time, due to personal reasons and RL problems. :/


S422 reached n=200K, 1 prime found and already reported. Releasing this base

Can you give us a status on R323 and S406 that are around 6 months old? Thanks.
