Unfortunately, newpgen still crashes after setting affinity. I tried multiple computers. Winpfgw seems to have the same problem.

I will put as many machines as possible to sieving -- 3 at most.
Athlon 1800Mhz, Athlon64 1800Mhz, Celeron 1200Mhz.

I can also take the bookkeeping task: collecting files with factors.

I'd like to start the sieving of an exponent from scratch, for example the next after n=333,333.

I regularly will upload pre-sieved files on site twinprimesearch.org (pre-sieved files for n=333,333 coming from somebody else and pre-sieved files for n=xxx,xxx coming from me)

Is it possible ?

Hmm, there are some 333.333 primes with pretty high k-values reported : http://primes.utm.edu/bios/code.php?code=L214 . Could be some competition from david broadhurst. Let's see if there are some more primes coming.

I assume that is a test of software limitations.

Everyone is free to to find own primes...
