I have corrected that.

S1027 has been sieved to 50G.
833,933 factors found. I´ll move this base to my brand new server (#3). I predict it will take 3 to 6 weeks.

I created an sr2cache with the -c command. This file is 1,2 GB huge, it has 7,7 Million lines! What the heck is in it? If I open it with n++ I see only not translabled code.
Example:

Code:

    ¤p   ÿƒC 9u

That is only used to resume jobs that take a while to resume, without it, you will lose up to few hours every time you resume the job, by redoing the "startup" calculations every time. If this is ok for you (assuming you do not resume more than once or twice in the life of the job, unless you really have a shitty system or bad electricity supply), you don't need that file.

hi,
reserving R709, n=100k to 200k to sieve for BOINC
reserving R710, n=100k to 200k to sieve for BOINC

Short sieving status update:

S17: ATM@48,9T 336 sec/factor.
Goal was 90T, might sieve deeper. Will be at goal on 7.12

S844 will be finished in 7 hrs, sec/factor is already close to prp-time needed.
Goal: 20T

S1027: ATM@0,35T. This was reached in about 2 days, but sr2sieve said it will be at 1T in about 9 days.

Reserve S218 and S257 to n=1M.

S257 is already sieved, see Sierp conjecture reservation page: http://www.noprimeleftbehind.net/cru...e-reserves.htm

S844 has been sieved to 20T, time/factor higher then avg PRP test.
File attached.

You can check whether the list is correct.

sweety439, I'm not sure if you are a troll or not. I prefer to think that you are not a troll and that you have genuine and sincere reasons to be here. Therefor, please sweety439, stop making any further reservations and reach out to me in a private message. I'm more than willing to help you understand how the various programs work and how to calculate how much effort it actually takes to complete a reservation - weather it be a sieve or primality reservation.

This projects really could use many more contributors and many more ressources, however if someone does a lot of work and does it wrong, they end up hurting this project more than they benefit this project. So please, sweety439, reach out in a private message and let's see if you and I can make you a positive contribution to the CRUS (original definition) project. Looking forward to be hearing from you

Take care!

S758 is sieved to P=30e12. I used 6 threads, so the time per factor is a little wonky, but it should be ready to go.

Edit: Reserving S320 (k=97) for sieving n=200k-500k.
