Srsieve is very inefficient other than to get started. Peter, there are instructions in the "come join us" thread for running srsieve/sr2sieve. Sr2sieve can be a little tricky if you've never used it before. But once you've used it a couple of times, it's real easy.

I have corrected my above post. The sieving removal rate for testing the range of n=2500 (or 1000) to 25000 should be in the ~30-60 second range depending on the base; not 2 seconds, regardless of whether it is srsieve or sr2sieve. A removal rate of 2 seconds would be well undersieved.

For the initiated, this is because a test at the 50-60% of such an n-range, i.e. n=13K-14K, will take 30-60 seconds.

Don't forget that the size of the base also has an impact. Smaller bases take less time for PRP tests than larger bases for the same n. For example, at about b=400, a PRP test at n=25000 would take 2 minutes, but for b=900 at n=25000 would take about 4 minutes on the same computer. Note that those are estimates.

just to clarify:
There was only one mistake in the untested Sierp page. All other Sierp/Riesel bases are really untested. But its always good to check the reservations page before you start a new base.

I'm very sorry but the servers and web pages were out for 10 hours today. See here for an explanation. Everything is back up now.

Greetings from TheCount! I am interested in trying something new. Been crunching on Primegrid for a while and only getting more interested in finding out about Prime finding. I currently have 2 primes in the top 5000.

Can I use PRPNet client 5.2.4 with server=G1400:100:1:noprimeleftbehind.net:1400 to get started with CRUS?

G1400 is available to everyone. Welcome and good luck.

On http://noprimeleftbehind.net:1400/pending_tests.html you can see that the Age + Expires times on the assignments add up to 72 hours (for the port 1400 server).

I would like to help but have no idea whats going on here can anyone explain it to me? (if this is too far off topic for the tread tell me and I will start another with this express purpose in mind.)

I suggest that you start here.

Has anyone a starter sample how to run a new CRUS base with pfgw (prefer llr)? Iam really interested in, later perhaps on a BOINC project if I can understand all the things which I needed.
