While I have not done anything that takes around a year, I have done GIMPS tasks that take well over a month.

If you will not reserve S606 for me, that's fine -- I'll look into your suggestions, more GIMPS work, or other BOINC projects. However, I ask that you allow me to reserve it. I'll send you progress reports as often as you want as proof that I'm sticking with it. One if my flaws is being stubborn :)

Will you be using PRPNet to distribute the work across the various computers and cores?

[germanNinja]

No. I used srfile to split up the work by k, and again to combine multiple k's together in a sieve file. If one computer runs out of work, it is fairly simple for me to split the largest file again. The computer I bring to school has to go through the school's proxy which blocks PRPNET, at least for primegrid.

Rogue this idea was always on my mind, but reading , and setup PRPNet is definitely is not easy task , especially if you dont have knowledge for that kind of work. So I take piece or work and split in XLS table :) It is faster :)

What is difficult with it? Installing a database is the hardest part. PM me with questions.

It probably won't block if within the network, but there is only one way to find out.

BTW, what is the right options to test CRUS bases on PRPNet? I'd tried to use servertype=1 and servertype=3, in both cases search continues despite of fact that prime for specific k has been already found. I remember in early versions of PRPNet (4.x maybe) there was 'sierpinskiriesel=1' option that prevented such behavior. Any suggestions?

servertype=1

If you have more k then clients, then you might also want:

onekperinstance=1

If you e-mail me your prpserver.log I can take a look at what is happening.

Can someone post the latest Windows version of srsieve2 here along with a README or other help file that shows how to use it ?

I would like to do some sieving on many k's for Riesel base 3. All are k > 25G.

Thank you.

Thank you.

1. Download mtsieve here: https://sourceforge.net/projects/mtsieve/files/ (left click the file and choose open or save when asked by the browser)

2. Unzip or open folder and copy srsieve2 to your working folder

3. open cmd prompt as administrator or directly from the working folder using shift+right click on mouse and choose "open commandwindow"

4. type following in the new commandwindow:

srsieve2 -P (max sieve value) -w 10000000 (can be excluded but I have found on my quad that I'll run faster if I set w(orksize) to 10M primes compared to 1M primes as default per thread) -W (number of threads you want srsieve2 to use, it makes no sence to not set it to the amount of available threads) -n (min n value) -N (Max n value) -s (name of sequence file)

5. Hit enter and srsieve2 should start processing work at once

This will get you going from scratch

In case of problems, throw me a PM and I'll try to help you

Take care and stay safe.

If resume is nescesarily at any point, I think this will work:

srsieve2 -p (min sieve value to start from - may not be nescessary if using all threads) -P (max sieve value) -w 10000000 (can be excluded but I have found on my quad that I'll run faster if I set w(orksize) to 10M primes compared to 1M primes as default per thread) -W (number of threads you want srsieve2 to use, it makes no sence to not set it to the amount of available threads) -n (min n value) -N (Max n value) -i (name of output file created in point 5 or file created by srsieve or srfile that needs further sieving)

[rogue]

srsieve2 cannot read some formats output by srsieve/srfile. You will want output from those programs to be in "pfgw" format so that srsieve2 can read them.

Note that srsieve2 does not support Legendre tables yet. I should have some time to work on that in the near future.

Of course any suggestions for improvements are welcome.
