Hi,

I just got an email from Primegrid saying I found a GFN-15 prime, but when I look at the workunit in question, it has not been double-checked yet (looks like the wingman will probably return it in a few hours).

Is this normal? I thought a prime had to be double checked before a confirmation email is sent out. Admittedly this is a small prime, outside the top 5k, but still seems premature...

As an aside, the prime count has not yet updated in my sub-project counts on my account homepage; presumably waiting for the double-check to confirm it is valid first.

Thanks,
Darryl

Recall that GFN runs a PROBABLE prime test (PRP) and not an actual primality test. Because it's only a PRP test, every time a a GFN PRP is found, the server runs an actual (and much longer) primality test on the number.

Left on its own, the server won't start that primality test until the tasks are validated with two tasks completed. However, Jim or I have a display that shows prime (or PRP) results even when there's just one. We'll manually start the server's primality test so that things complete a little sooner.

Sometimes, the server's primality test completes before the wingman's task comes in. At that point, we have your PRP result and the server's primality test, and that's sufficient.

Congrats for the finding.
