Even on base 2 this program is faster then Newpgen. I can say it has constant rate for every base ( not just for base2 like Newpgen have)
Little test
I made sample file for base 500
Start point was 10000000000000
Newpgen done until 10016239604068 in 337 seconds and found 7 factors
In same time ( number of worker 1) FBCNsieve found 50 factors and reach 10100000000000.
In any way his program will give boost for searching type of variable K.
Can you improve sr1sieve in similar way ( add MT option)?
How was the newpgen file created? Was it created by newpgen or fbnciseve? Is there a reason that you choose that format over the ABC or ABCD format?

Getting sr1sieve into mtsieve is one of my goals, but it is behind the GPU options.
