New Base
 

Reserving R726 and S726 using new base script up to 2.5k.

[QUOTE=dannyridel;536940]Reserving R726 and S726 using new base script up to 2.5k.[/QUOTE]

These are very large conjectures. Can we ask what your resources are before reserving them for you? Thank you.

There are many new bases available with much smaller conjectures.

Ian and I have completed R820 to n=25K; 288 primes were found for n=10K-25K shown below; 527 k's remain; base released.

AMD R5 2500 4C8T, should I just take S726 which is already under testing?(at k=40000)

sorry for the double post; I have bad network

[QUOTE=dannyridel;536968]AMD R5 2500 4C8T, should I just take S726 which is already under testing?(at k=40000)[/QUOTE]

According to [URL=https://www.mersenneforum.org/showthread.php?t=12983]this thread[/URL], S726 hasn’t been started yet. Not to also mention that starting a new base can be difficult, especially for a newcomer to the project.
May I suggest, if you are interested in bases >500, to consider S542 or R653, which should be “easier”.

[QUOTE=dannyridel;536968]AMD R5 2500 4C8T, should I just take S726 which is already under testing?(at k=40000)[/QUOTE]


OK I'll reserve only S726 for you although that is still a lot of work. Here is what I suggest: Estimate how much time it will take you to complete the entire base by extrapolating: Divide the conjecture by 40000 (your current completion). Now multiply that by the amount of time it took you to complete to k=40000. Add about 10-15% because larger k's take a little longer to test. That should give you a good estimate of how long the base will take.

With a conjecture of k=10923176.for S726 it will take you almost 300 times as long to test the whole base to n=2500 as it did to test k<=40000 to n=2500. So if it took you a day to test to k=40000 it will take around 10 months to test the whole base running your machine the entire time. If you divide it among 4 cores running full time that is still 2.5 months. Are you willing to commit to that?

So 40000 is 10 hours, and totally I run it on 2 cores which cuts it down to 1.5months but since it's not running full time about 3months.

OK S726 is reserved for you.
