It's not impossible that's the cause, but I don't have a spare one lying around and I'm not ready to buy a new one on a whim that it might be the cause. Maybe when I need to replace the machine anyways I'll give it a shot, but it'll be even older by then :smile:

OTOH, me is back... :flex:

Welcome back! Where you been? :hello:

Holiday, back to Ro for a month. Now back to Th. Unfortunately only half of the capacity is up, because I can't find the time to refill the water pipes for the biggest machine. At job, there were few hundred mails waiting for me... ye know how it is after holiday... :smile: and the days are a bit longer and busier right now ...

Still didn't get the mosfet for the Titan, only the inductor was waiting on my desk, so the motivation to start the big mill is also not very high.. I could run it only with the 580's but welllll... Waiting for better days right now...

Getting stupid.. replying to myself... (again!)

Who is the Anon user with 8000GHzD/D output? He is now on the second position after Squirrels in the weekly report, but this is only because he started 5 days ago (so not yer a full week completed!).

And offtopic, continuing the former discussion (well, maybe ontopic too, it is GPU-related, and the GPU will do TF when it will be installed, and free :smile:)

Well, I got the mosfet, I replaced it, but the Titan still won't work properly, it looks like it is clocked very low (50MHz!?) and it can not go higher. The problem is that I can't really measure it, voltages, ticks, etc, because I need to install the radiator and put it in the socket (it gets hot without it) and in that position I can not access any measuring points. I will have to solder wires and spend a lot of time with it, and I am not sure I am able to fix it.

Therefore, I was in big doubt if I should "give away" the ~2500GHzDays of credit and send the file for somebody to continue the work. Who didn't know the story, I was DC-ing M332219809 in parallel with Manfred, at his request, we were checking/matching residues every 5M, and I was waiting for him, because my Titan was faster than his CPU, but then my Titan crashed and he continued by himself - and reported the result during my holiday, it was his assignment anyhow, hopefully is correct - we had a match up to 145M iterations, without errors on any side, and I have completed 149M.xxx iterations (very close to the 150M checkpoint, but not reached). My 580 cards are the one with smaller RAM (one G and half), so I could not continue the test. The 3G RAM 580 cards can run the larger FFT well, but I don't have such cards. The hope was to repair the Titan, but the holiday delayed it, right now the chances are very slim to fix it. The DC (if completed) worth about 5000GHzDays, and it is about half done, so I was quite reticent to "give them away" :razz: hehe, so guess what did I do? I looked for another Titan on ebay, and Mike (Xyzzy) is helping me to buy it. :fusion:

But, if you get desperate, let me know.

LaurV 2015-08-25 12:34

Well, the trade for a new Titan is "almost done" and it will be in my rig soon. And I still have (small small tiny tiny) hope to repair the old one. I am not getting desperate, and if I give it away, it would be to a guy (girl?) with a Titan, the time is shorter by half and much better use of the resources. I am sure few guys here have Titans, and even Teslas.

manfred4 2015-08-25 12:58

Oh, so you are really desperate about having your assignment get completed? That is good, because if you finally check in your result that would be a final proof, that all of the 4 cores that have been working on that are pretty reliable. :smile:

And that anonymous user is again really interesting - if he continiues to work at that pace it looks like our combined throughput on GPU72 has greatly increased with those two new top score users in the recent past.

Indeed! I don't know who it is either (and if I did know I couldn't tell anyone). But between them they're almost completing work faster than I can bring it in! :smile:

Mark Rose 2015-08-25 14:20

I remember only two weeks when my 1300 GHzD/D felt significant lol

Progress last 2 days (4:00 PM UTC): ... ROUNDED
DISCLAIMER: I know it depends on how often/when each of you check in results:

Mark Rose: +2,700
Air Squirrels: +28,700
ANONYMOUS: +22,300

To compare this shows just over 304,000 total DCTF in the last 30 days:
[url]http://www.gpu72.com/reports/workers/dctf/month/[/url]
47% of it is the Big-2 (Sorry Mark)

If the big-2 above continue at this rate they alone would complete 765,000 in 30 days.


All times are UTC. The time now is 23:16.
