[QUOTE=Aramis Wyler;324853]Damn, that's a lot of RAM. I only have 1 core doing P-1, but that 1 core uses up all of my memory. All the other cores do LL work, and the GPU does TF.[/QUOTE]

This system is a x6 1090t with 16GB RAM. It now seems that it can handle 480 Rel. Primes with 4 HighMem workers out of 6. I have 12.5GB allowed for P95. It is set to pause if I run Adobe Bridge or Photoshop.

On the left columns, if you click "tabular data" and play with the time line you will see that they come from bringing up 67 bit, whose column is not on the "changes" table anymore (why? no idea), and that confused the calculus, as they have to "match" (sum of positives plus sum of negative), therefore it may look like for 34M there are some "disappearences" (minus in 69 but no plus after it, they did go nowhere). It seems the numbers are right, but wrong placed, a display-only problem.

[QUOTE=chalsall;324799]Thank's for that information. Interesting.

So, a question directly to you (as our largest DCTF producer by far)... Do you want to start taking 33Ms up to 71?[/QUOTE]
Having the 33M at 71 will work for me, as that is where I am currently working. Adding that bit level may also 'shorten' the DC wavefront as it were.

I'm aware, I was just laughing at the supposed increase in unfactored exponents for the 30-40M range as a whole :razz:

OK, great. I've adjusted the DCTF Get Assignment form, all the reports, and the release spider.

Also, if anyone wants to, I've also adjusted the "No P-1 Done" option to take the DC P-1 candidates from 71 to 72 (working from the top down) for anyone who's interested in doing that work.

Maybe this should be in the Unhappy Me Thread, but anyway.

Some not so good news is that my father-in-law is not doing well, but we knew this was coming for some time.

Unfortunately, we are the only ones capable of helping him now. So, after a good run of ~13 months on G72, I'm going to have to sell off the systems and relocate. It could be as soon as 2 weeks or as long as as a couple of months. I'll keep the systems up and running for as long as I can. Hopefully, once we get settled in our new place I can get something put back together.

If anyone is interested in some great TF GTX 580s or a whole i7 system, PM me.

I'm so sorry.

To share... I lost my father at the beginning of this year.

Even though we weren't very close, and it was expected (he was 87, and sick for a long time) it was still a deep shock.

Some good advice I received from an old family friend -- drink lots of water. And feel free to cry... :cry:

Do what you need to do. And thanks for everything you've done.

LaurV 2013-01-17 02:03

Jerry, thank you a lot for what you did here around, and we hope your father-in-law get well soon, and we will see you back on the barricades, maybe even sooner, with a small "put back together thing".

Your "windows builds" for different tools helped me a lot, personally, and saved me a lot of time.

FWIW, I lost my father-in-law in December, my wife was very sad and desperate, but the sadness is slowly passing, and in time we only remember good things.

kladner 2013-01-17 03:25

Best wishes for all concerned, Jerry. You (and your throughput!) will be missed.
Take care,
Kieren
