1) Message boards : Graphics cards (GPUs) : GTX 650ti work? (Message 47250)
Posted 191 days ago by Profile God is Love, JC proves it...
You should be able to run GPUGRIG WUs.

Having started with a 530, a few years ago I upgraded to a 640. (Please note that I am NOT a gamer, not at all.) I can run WUs OK, but it takes 2.3 to 8.8 times as long (times the averages given in the Performance page) on the 640.
If short runs are available, I tend to run those. However, even when only long run WUs are being generated, my 'lil 640 is chunking along OK. (Note that I keep my PC running 24/7.)
I had of late been giving MUCH thought to upgrading again. However, I am not going to invest in an external power supply. So, I'm rather limited to 750s or 1050s by power constraints. For now, I am not interested in spending $150 or so for such an upgrade**, when the 640 is still running fine.

In fact, in early March (2017) I DID buy a 750Ti, over Ebay. (not used, not reconditioned... straight from a factory in China) BIG mistake. While the price was 'good' ($77), I was taken badly. After having installed it (and I had to buy a different power connector), I realized (TechPowerUp GPU-Z as well as Nvidia GeForce Experience) that I had been 'sold a bill of goods.' Although NVidia and GeForce where written all over the unit, and the logos everywhere, the GPU was, essentially, junk. It only had 192 cores, while the NVidia specs are for 640. Well, as my existing GT 640 had 384 cores, I put that thing back in.
It took some two dozen rounds of emails, threats about reporting these Ebay con-artists to NVidia, etc. etc, but luckily I was finally able to get my money back.

** PS, I work from home several days a week, and having dual monitors is important for my productivity. Neither of my monitors has a DHMI input, so I am also limited in my choice of GPU models in this regard as well.

Not sure if there might be a better thread for this question, especially as it has been ignored for nearly four weeks, but I concur (mostly):

"My only concern about this project is how long it will be running. Before I put more money to it, I'd like to feel at ease that it won't end any time soon(possibly a time estimate on how long it will run?). Might seem foolish but I see these other projects closing down. I don't want to go out and buy something and then have this project be done."

While I do run quite a few other projects, I (try to) use my GPU exclusively for GpuGrid. (A reasonable alternative was POEM, but that has now folded [pun intended]). I have in the past (about 3-4 years ago) invested in a (+- small) upgrade. I am pondering doing so again. As I've posted before: I am NOT a gamer. I have a GPU solely to support scientific computing projects.

SO, some moderator,... any moderator... any idea how long GPU might keep rolling along?
I presume this really is a question not for a moderator, but for some of the academic faculty doing research which feeds the computing needs for this project.

Thanks,

3) Message boards : Server and website : IS the 5-day (120 hour) time limit enforced on WUs making progress?? (Message 46328)
Posted 302 days ago by Profile God is Love, JC proves it...
Uncertainty about the timeout being enforced comes from the fact that the Performance page will list several batches with maximum run time (in the box-plots) of well over 120 hours.

In the past couple of weeks, the lion's share of WUs have been running very, very long.
In the past week or so, I have aborted a dozen or more WUs because, while running, they were heading to well over 5 days of compute time.
At this posting I have a WU running with anticipated completion time of just over 11 days (270 hours). I really would like to run this one, since I have not been able to run any GPUGRID WUs in nearly two weeks.

Thanks.

PS I asked this question on the BNBS thread as part of a post there, but I think the question if pretty important overall for GPUGRID

4) Message boards : Graphics cards (GPUs) : Long runs have too short deadline (Message 46327)
Posted 302 days ago by Profile God is Love, JC proves it...
First, I'd like to say that I really like supporting GPUGRID as a project. The team publishes results. Also, it seems so many other distributed (grid) computing projects are in theoretical math or in astronomy. I LIKE supporting a project which we can hope will improve human health down the road.

I have a pretty modest GPU (GT 640**) compared to many GPUGRID hosts. However, I have been averaging right at 11 WU a month (almost every single one long-run). Also, I imagine that I am far from unique... that there are many BOINC volunteers 'out there' who have a more modest system (not costing a grand or more, and with no external power supply.)
I appreciate that timely turn-around is important, but there is no other BOINC project of which I am aware with such a short time-out limit on WUs (I am active in 15 projects, not counting several which have by now ended). Ten to 20 days is pretty typically the time limit. SETI has a time limit of over 5 weeks.
So, my question: Is GPUGRID snubbing potential BOINC volunteers who have, say, a GeForce, but not a Titan or whatever?

Thanks.

** Some 6 years ago, I had a system with a 530. A couple of years later, I upgraded to a 640... I didn't go for more so as to keep my expense to under $100, AND not to have to buy an external power supply.
By the way, I am NOT a gamer at all. I bought the GPU solely to support distributed computing science projects.

Greetings;
First, I want to say that I really like supporting GPUGRID as a project. The team publishes results. Also, it seems so many other distributed (grid) computing projects are in theoretical math or in astronomy. I LIKE supporting a project which we can hope will improve human health down the road.
I have a pretty modest GPU (GT 640**) compared to many GPUGRID hosts. However, I have been averaging right at 11 WU a month.

So, my First question: Is GPUGRID snubbing potential BOINC volunteers who have, say, a GeForce, but not a Titan or whatever? (This part of the post is perhaps better fitted to another forum.)

In the past couple of weeks, the lion's share of WUs have been BNBS -- and they have been running very, very long.
My second and MAIN question is: is the 5 day timeout enforced on tasks, even if they are making progress?
In the past week or so, I have abort a dozen or more BNBS WUs because, while running, they were heading to 300+ hours of compute time.
At this posting I have a WU running with anticipated completion time of jut over 11 days (270 hours). I really would like to run this one, since I have not been able to run any GPUGRID WUs in nearly two weeks. (In the past POEM was a good backup project, but they have recently terminated.)

My uncertainty about the timeout being enforced comes from the fact that the Performance page will list several batches with maximum run time (in the box-plots) of well over 120 hours.

Yes, deleting the task and getting a new one seems to have worked.
However, the question is STILL unanswered.
John C MacAlister posted this same problem--issue, a couple of years ago... and HE never got a real answer either (not on the boards).

PS I have deleted the WU, and am trying to get another one (:
So, when I get the next WU I guess for now I just have to keep 'my fingers crossed' that the problem does not recur.

BTW, it is not, I don't believe, a matter of WUs interfering with each other.
Milkyway is using OpenCL.
When I suspend all Milkyway WUs, the same error still keeps coming up for GpuGrid
2016-12-20 4:53:19 PM | GPUGRID | task postponed 600.000000 sec: Waiting to acquire lock

In fact, when I suspend the Milkyway project, the same error still keeps coming up for GpuGrid

Other 'tidbits'
There seems to be no way to restart the task before the 10 min (600.0 sec) has lapsed.
This error always happens right at 30 sec into the task running, and
... each time I suspend other gpu tasks, WT_S3F1_C3-SDOERR_BNBS-0-4-RND3170_1 restarts from 0:00 time elapsed.

I keep getting a strange error, despite having been running GPU for a couple of years now.

10) Message boards : Number crunching : All Gerard WUs erroring (Message 42566)
Posted 687 days ago by Profile God is Love, JC proves it...
WU e15s19_e14s24p1f286-GERARD_CXCL12_DIMPROTO3-0-1-RND3500_2 has been stuck at '85% "progress" ' for some 12 hours now.
I only have a 640, so WUs take 40-60 hours generally.
This task has already run for 69:58.
is this part of a defective batch?
How many more hours should I sacrifice for this WU?
I am presuming that if I abort it, there will be zero credit for these 70 hours (even if it is a flawed WU?)

I Run Win 7 on my HP-1120, i7-2600. (I am NOT going to 'upgrade' to Win 10 for months, until (I hope) MS gets all the garbage in Win8-10 patched up.)

Please advise.

Meanwhile I have paused it and am putting my GPU to better use.

Thanks.
