LOL... Coding needs periods of calmness...

"Talking loudly and quickly" to my suppliers, my employees, my bosses and other forum members in real-time all flows into a different mental state....

I like this Aramis bloke/ss.

Coding at it's best does indeed involve a certain mind-set.
Not especially well-suited to sociability!

I could clean up this flat in a day or so if it wasn't for Mersenneforum distracting me the whole time.

Also periodically re-read Gerald Weinberg's "The Psychology of Computer Programming", originally published in 1971. Take special note of "egoless programming".

And, or... Perhaps The Mythical Man-Month?

It's an old one, but a good one....

OK, to let everyone know...

Based on my calculations, we should be able to sustainability start going to 74 "bits" at 63M and above. This is based on the current rate of Primenet completions (~312 per day over the last week), our current rate (~500 per day to 73 or above over the last month), and the fact that Primenet will start releasing candidates assigned after the "big announcement" in a couple of weeks or so.

If my calculations are wrong, we have 4,850 candidates already at 73 we can release back when and if needed.

I have adjusted the Available Assignments, Released TF Level and Estimated Completion reports accordingly. Additionally, I have added a new line (>73) to the Overall System Progress graphs, and adjusted the Linear Regression line to take this into account.

I will change the default TF level on the "Get LLTF Assignment" form to be 74 once we've cleared out (or, at least, assigned) all of 62M to 73 (approximately one week).

As always, people are free to take those candidates we hold for P-1'ing below 63M to 74 if they wish, or to not go to 74 when that becomes the default.

oooohhhhh the drama; the anticipation!!!!

Sounds all good to me...

...exactly what I have been advocating for over 2 years.

Good to know that the bit level that James judges the optimal is also feasible with current firepower

But it is not desirable to hoard 3000 assignments at a time. 60 users with 1000 each would do it 3x faster than 20 with 3000.

**********

I note that the expected time to the next prime has dropped from 6 years to 4 in the last year. TFing to 5 more bits accounts for a reduction of 7%.
I expect AVX accounts for the rest.

Each new prime needs ~ 3 times as much computing as its predecessor. For this to occur every 4 years seems a reasonable expectation.

Starting to get TF assignments to 74.
