Nice one Kenneth!

48697*16^350218+1 is prime!

S16 is complete to n=350K.

Take care

Nice run of primes Kenneth!

Are you complete thru n=360K?

A very nice run indeed

I should have been more clear on the searchlimits. I never really got befriended with MySQL so I haven't been successfull when it comes to making PRPnet work. This means that the testlimits is as follows:

Trailing edge: n=356,012
Leading edge: n=361,655

This means 3 cores is running below n=360K and 1 core is running above n=360K. I expect this gap to grow bigger, since 1 core has had 1 prime and 1 core has had 2 primes, while 2 cores has had no primes at all

On a final note, this is my 4th Top5000 prime in April, so I've actually had a very prime month

Take care

Kenneth

If you can't get mysql to work you could either use the pre-sql prpnet or llrnet.

I think he means that he hasn't spent the time on it. Getting it to work isn't too bad, but the complexity varies from OS to OS.

PostGreSQL is also an option and I suspect it would be easy to get it to run on most other databases.

If he really wants to run on PRPNet, he can reach out to me.

S16 is now complete to n=360K. On a sidenote, I'm getting closer and closer to getting PRPnet to work, so maybe we will eventually see an even leading edge

That statement means that I would have to make code changes to run on other databases, but I doubt it would too much work. I have a lot of experience with Oracle and some with SQL Server. As PRPNet doesn't typically require a large footprint, I would consider those databases to be overkill.

I finally made it. It's now official, I'm running the 18 candidates remaining for S16 on my own dedicated PRPnet server. Thank you Rogue, for your great explanations and large patience

Because I run PRPnet, I can give you the following numbers:

Trailing edge is: n=363,902
Tests remaining: 31,798

Take care

S16 is tested to n=370K. Nothing new found, Continuing happily!

I'm going to participate in the ESP challenge, due in about 26 hours from now, at Primegrid, so don't expect such a rapid ascend toward n=380K
