Alternative Sieving for 10M digit prime search

I tested the number 1000000+1 (which is composite, prp test) with P95 V25, it did not found a factor it. For finding a factor you have to increase B1 & B2 bounds. IMHO.

I see what you mean...

New file (next update in 1 week)

All values are tested to 1017000 and removed from file. I haven't started PRP yet. Will start soon.

Finding time for a factor has increased to 17800+ seconds (5 hour 30 minutes +)

Citrix,

Did you see the factors from this post?

I missed them. Carlos, I prefer If you do not zip the factors, just attach the text files. Secondly, send the factors once the entire range is done or once a week. This makes it easier for me to keep track.

CedricVonck, something might be wrong with your computer. It should take 1-2 hrs per factor. I have reserved

43046721 1017600

for you. This has 1 extra number n=1017888 in it. So we will be done to 1018K and things are easier for me to keep track. Please post your p-1 times and factors here. Also post the LLR residues here.

Thanks.

edit: If it is really taking 5 hrs per factor, we should finish sieving till 120T and start LLR till n=2M. Once at 2M we can switch back to sieving.

Citrix,

I added the number to my crunch list.

p-1 timings: I have to make a new input file, but I guestimate it is under 10 minutes.

I am stopping my range to crunching:

I am @ 105163207992289

Releasing 60T-75T and 85T-100T.

Carlos, why are you releasing your range? I think your range should be done before we start PRPing.

Because I want to move everything to the Cullen project.
