Well done Dingo!  Plus one.

Looks like I found a new Prime Number today 2016-04-01 00:55:09 UTC.  The prime number is 2673304915647 · 21290000 - 1 but is not a high ranking on the scale.  It is a large number thoughwith 388342 decimal digits  http://www.primegrid.com/primes/?section=decimal&primeid=98448.


EDIT Looks like it was large enough to make the Largest Known Primes Database.

I've been doing some crunching for PrimeGrid too lately, mainly using my GPUs on the PPS (Sieve) application.

That's cool, good work Dingo! I've always wanted to find one, or a pulsar with einstein@home.

I found another one with  (388342 decimal digits). 

I think the answer is to only run primegrid on the PC and also set the "Minimum" and "Maximum work Buffer" to 00.00 so that the tasks are processed and returned quickly.  This way to are the first to return the result and if it is prime you are the finder and  not the authenticator.
