[QUOTE=carpetpool;450159]Good point. I will un-reserve S223 for now. S15 seems adequate. Any other suggestions?[/QUOTE]
S 15 is also hard for beginning.
Look at S70. It has sieve file already, so you just need to start :)
I dont know what number of cores you have: but for start take range from 250K to 500K

If you want to assist on a base that has been started, but has a lot of remaining work, use srbsieve with S3 and bite off 1G. Another option is to take a range from R3 from n=25K to n=50K. There are quite a few.

What we recommend though will be highly dependent upon how many cores you have available.

If its okay with everyone, I'll be reserving S123 to n = 100k-250k. Running on an I3 possessor. There was already a sieve file for this base.

Did you make one test, so, you can estimate total time ?
Dont take big bite for first time.:smile:

I do not recommend bases 3, 7, or 15 for a new person. That's a lot of overhead and admin and a lot of potential for problems with such big files.

S123 for n=100K-250K is good.

To get an estimate of how much CPU time it will take, please run a test at n=190K. Then multiply the test time by the number of total tests in the file. That should give a good rough estimate of how long it will take. You may find that you want to only do n=100K-150K or 100K-200K.

[QUOTE=rogue;450154]Actually we do use newpgen to build the input files to srbsieve.[/QUOTE]

Yes but that's the only time.

Also reserving (for sieving only) R163 to n = 250k (there's only one k value left!!!)

VBCurtis 2016-12-31 04:46

R112 complete to 300k. Extending reservation to 350k.

[QUOTE=carpetpool;450183]Also reserving (for sieving only) R163 to n = 250k (there's only one k value left!!!)[/QUOTE]

R163 has already been tested to n=400k.

rebirther 2017-01-01 12:29

S148 tested to n=1M (533k-1M)

nothing found, 1 remain

Results emailed - Base released

gd_barnes 2017-01-03 05:48

Reserving S117 to n=250K.
