I have finished the range that I had reserved. No primes. I will reserve more work soon.

[ValerieVonck]

Citrix,

Can you make available a new dat file and provide a list
ranges that have to be sieved?

Thank you!

Thank you!

I don't see any point of sieving upto n=4M, since very few people are participating in this project. What N should we sieve upto? I think 1M to 1.25M would be a good range.

What do you think?

[ValerieVonck]

Citrix,

N= 1051952 took about 4000 seconds to test.
I don't know how long it would take to test n=1.250.000.
Best guess is 6000 sec's. (probably less)

I will do a couple of tests with my (modified) dat file that contains numbers from
1057888 till 1250048 (1950 candidates).

I will test from 60T to 65T.
I will report how long this would take and if any factors were found.
(Expected factors : 4.90 :()
Expected due date: tommorow around 20.30

Regards
C.

Are they not working on K=9 at "15k.org" from scrach (are in range of 850k at the moment) ?

Yes we are.

[ValerieVonck]

Ok I will asap.

sieve results for the range 34M => 50M are available @ http://users.skynet.be/bk261068/9_34M_50M.zip.

Will try to upload the other input file (<34M) asap to my siite
or to another site.
