[QUOTE=James Heinrich;316381]Is this unexpected? [/QUOTE]

There aren't 20,000,000 primes in the 20.0M range all at 58 bits.

Compare it to either adjacent range (i.e 30M).

That's an "unfortunate" way of displaying the fact that no progress was done, in the "changes" mode. They would all be zero (i.e. the table should show only columns 60 to 68 and be ALL empty). This is very old (years, long before gpu72 was born, the visualization site is much older) known bug (by chalsall too) but it does not bother, use zoom out :razz:.

So, it does not show the exponents amount, but the changes only. If you want to see the amount of prime exponents, click on "tabular data" thing (not on "changes" thing, which displays tabular "[I]delta[/I]" - see the url).

GPU72 is one year old!!!
 

Today is GPU72's first birthday!

One year ago today [URL="http://mersenneforum.org/showpost.php?p=276621&postcount=197"]I first made available the GPU to 72 Tool.[/URL] This came out of discussions based on Mr. P-1 coordinating GPU TF work with about a dozen "workers" manually. I volunteered to offer a semi-automated system to coordinate the work.

Silly me... I figured it would take about a week to build a system which would be "good enough".

Then, serious feature creep set in...

Then, some very serious firepower manifested...

And the rest is history! :smile:

Who could have imagined at that time that in only a single year our combined efforts could have brought [B][I][U]everything[/U][/I][/B] [URL="https://www.gpu72.com/reports/estimated_completion/primenet/"]in the LL range below 57M to 72 bits, and everything between 57M and 58M to 73 bits[/URL]? Further, we are only [URL="https://www.gpu72.com/reports/estimated_completion/"]approximately two weeks away from bringing everything between 58M and 60M to 73 bits[/URL]!

Additionally, we also brought everything in the DC range to 70 bits, and are less than a week away from completing the 31M range to 71.

As of today, we've found a total of [URL="https://www.gpu72.com/reports/overall/"]8,302 factors, saving the GIMPS effort[/URL] a total of 1,484,466 GHz Days (4,067 GHz YEARS) of LL, DC and P-1 work!!!

To commemorate the anniversary, I've added a new set of [URL="https://www.gpu72.com/reports/overall/graph/year/"]Yearly Overall System Progress Graphs[/URL].

Thanks for all the cycles everyone! It's been a lot of fun! :smile:

Huzzah!
 

Here's to many more successful cycles!

:toot::party::beer::w00t::toot:

:bow wave::party:

Thanks chalsall, for all your work!

btw, the new graph is really nice :D gives you a idea how it's been going.

Happy birthday !!!
 

Yes, that's really cool. What a project, and bold results. I'll drink on it.:groupwave::groupwave::groupwave:

yay! hip hip hooray! special dedication for chalsall

(mrs LaurV found these on the net looking for some xmass songs to start practicing with her class, two and three years old toddlers, they will do some acting on the "[URL="http://www.youtube.com/watch?v=VLrBzOXAhbQ&feature=related"]santa got sunburned, that is why is red[/URL]" of this band, hehe, I remember this band from my youth, together with other south american bands, my mom used to sing their songs and we had them on those old pickup disks, anyhow, i goin soca you, you goin soca me. :razz:)

Happy Bday GPU72 !! :paul::et_::joe o::groupwave::party:

Happy belated biiirthday!

Truly impressive results.
 

Now that is teamwork and dedication!
