At this time if you are sieving multiple sequences with srsieve2/srsieve2cl, use -l0 to force usage of the generic logic. Without it that command line option...

Taking S1004. Note that I do not expect to start on S1004 or R1019 for about 3 to 4 weeks. I took them now to sieve them further. Some that I have reserved in the past needed additional sieving. ...

That should be easy to do. I have asked for the changes, but nobody has provided them.

I have written the kernel, but it doesn't find any factors at this time. Probably something stupid.
