A great result! Well done to lucky finders :)

Thanks everyone! I have applied manual credit for all the testing done, and a few of you have earned nice shiny "volunteer tester" titles :)

Hi all,

Thanks again for all the testing effort. If anyone has access to SSE3 Mac or Linux hosts, it would be great to get coverage of some of those...

Great idea - out of interest, how what fraction of the candidates that pass (normal) sieving are consecutive? i.e. how much faster will this search proceed than the normal GFN prime search?

295 new GFN-14 primes were discovered between 10M and 20M. They will appear on history page soon.


Done!

I'm back and the google sheet is up-to-date. Thanks for all the testing so far.

We've made good progress on many of the tests - would be great if people could try running under app_info.xml and post links to completed (& validated) tasks.

Cheers

Yes, the MTBUG test is expected to produce some round-off errors and restarts during the test. In the previous version of LLR, this led to incorrect residues at the end. So as long as the final result is correct, actually in this case it's good to hit the round-off errors as it shows that the error recovery is now fixed.

FYI - I'm going to be away for a few days over the Easter weekend. I will try to check in but I may not be able to update the spreadsheet much as I'll be on my phone!

Probably not, I should have said I was a mile off the north end of the runway i.e. in Eastleigh proper, rather than Southampton itself.

Did you ever happen to be at the right place and at the right time with airplanes in the vicinity of the airport flying very close to the moon/sun? Such opportunities make for stunning photos and of the form "it must be photoshoped".


Most likely yes, but I've never been much of a photographer, much less one with the levels of planning and persistence needed to achieve such a well-composed shot!

Nothing left to do for AMD, as I understand it.


I think DeleteNull was happy to share out the tests - so feel free to pick one and run it (maybe the long MTBUG tests at the bottom of the table)?

Bank notes (bills) are issued by a handful of outfits in the UK. In England if you hope to be served you'll use an English GBP5, GBP10 or GBP20 note. You can try your luck with a Scots or Northern Irish note. I've seen 3 English GBP 50 notes but there is no way I'd accept one.


In Scotland the £50 is reasonably common, but it is still unusual to see a £100 note. As a student, I was once conducting a sale of an item out of a secluded lockup when the buyer presented three crisp £100 notes to settle the transaction. Fortunately, I had seen enough of them as I worked part-time in a cash'n'carry to be confident enough to accept them!
