Both !!!

It is good that they found it.

Bad because sieve will get slower to we find the problem.

No factors are removed from the sieve file before they are checked to be good.

That means 3M-6M is stopped at 400P and 6M-9M started on Boinc.

We do not use any sievefile. We sieve 5<k<9999 3M<n<6M in a given P range.
It is not faster with a sievefile and lets say you have 2000 computer downloading ~300Mb every month. :smile:

I shall check how much we can sieve.

Think about that we sieve for DC !!

We test all proth k's 3<k<10000

We sieve riesel/sierp (+1/-1) 5<k<10000 3M<n<6M. I have todo some tests if we can...

What hardware do you use when comparing sec/f ?
most sieving is done with GPU's.

If you compare with CPU sieve time I can agree, but most sieving are done with GPU's.

If the sieve time for a range was linear with the amount of candidates, yes we would have done smaller ranges. But that is not the case so we will continue to sieve as it is.

This is irrelevant data to decide what to sieve !!

The sievefiles covers 5<k<10000 3M<n<6M

Next sievefile covers 5<k<10000 6M<n<9M

I will start 3<k<10000 9M<n<12M soon. I...
