right now i'm at 4.3 billion... the rate is 1 n every 2.4 seconds...

Mike..

is that good?

That sound about right!

NiceMedTexMD 2005-12-08 19:32

update..
 
right now on the k that I picked....

Sieved up to 126.6 billion, 1 n every 83.4 seconds...

How far do I need to go?

Mike... :mellow:

That depends on how long it takes for LLR to run on a candidate.
You can try running LLR on the input file that you have for just
one number. Keep sieving until sieving removes candidates slower
than LLR would and then switch over to LLR. My guess would be
keep sieving until one candidate is removed for every 100-150 seconds.

Best thing to do is LLR the last n in your sieve file & note the time it takes. Then you will know how long to sieve

If NewPGen is running (on idle priority) while you are speed testing with llr you will need to set the priority of llr to at least 3 so that it takes about 99% of CPU time thus giving you an accurate timing.
