1906-1908 complete, no primes.

Taking 1924-1926.

The confusing thing about sr1sieve is that it doesn't create an initial sieve file so you have to create it in another program. A companion program called srsieve will create one, but since you already know newpgen you can use that. To be safe you need to sieve to at least p=1e9 in newpgen.

Then, if say your sieve file is called k17.txt, you can sieve to p=1T with the following command

sr1sieve -P 1e12 -i k17.txt -o k17.txt

which will remove factors from k17.txt like newpgen does.

sr1sieve -h will list the other parameters than can be used including ones to set the priority and the processor affinity.

Taking one file: 1926-1928, before all below 2M are gone!

Please note that all files below 2M are now uploaded.
The last one stops at n=1,967,592.

2330-2346 and 2900-2916, no primes.

I started this out of order search before pb386 revealed which ranges he was searching and decided I might as well complete it.
