Cooling 12GB appears to be a big issue and it's likely hindering boost and power consumption, but without the 12GB it wouldn't be a Titan, saying as it doesn't have good dp. Hopefully a GTX980Ti with 6GB will appear soon - perhaps 2688 cuda cores, akin to the original Titan, but 35 to 40% faster for here and <£800, if not <$700 would make it an attractive alternative to the Titan X.

Recent reports point to a full GM200 980Ti with 6GB - June/July launch.

That is very good news indeed.
Perhaps I'll wait for that card then.
6GB is ten times more than a GPUGrid task needs so it's an overkill.
Then 12GB would be ... complete waste of money.

You didn't miss it; it is missing!
GPUGrid hasn't done user of the day for years IIRC.

That's why I was surprised.

So it appears that you have been randomly chosen (by a 'back-end' process) for Nothing - Congratulations! ;p

"... for Nothing" (uhhh... 30 years old high end computer graphics)
LOL
Thanks :D

User of the Day normally appears on the front page and it's part of the Boinc web template.

It's working like that on the webpages of other projects.

I've received the following e-mail from GPUGRID server (noreply) <ps3grid@gmail.com>:
Congratulations!

You've been chosen as the GPUGRID user of the day!
Your profile will be featured on the GPUGRID website for the next 24 hours.

Well, that's nice. But I didn't find where my profile is featured here.
Am I so unobservant that I missed the right place, or is this feature missing from here?

When will the GPUGrid app support BigMaxwell?

Soon, but not imminently. AFAIK, no one's attached one yet.
(It's working here in the lab).

FYI, it's working now (on Windows 8.1).
Here is a short workunit processed successfully on a Titan X. (Thanks to eXaPower for pointing it out)

I'm planning to sell my old cards (GTX670s and GTX680s),

High roller! I'd have throught 980s would be more cost effective?

They are.
But as I will apparently loose my 2nd place on the overall toplist, I'd like to do it in a stylish manner.
So I shall continue to have the fastest GPUGrid host on the planet at least. ;)

Does anyone have such card to test the current client?
I'm planning to sell my old cards (GTX670s and GTX680s), and buy one BigMaxwell, as I want to reduce the heat (and the electricity bills) generated by my cards for the summer :)
I didn't bought more GTX980s because of this card (the Titan X), and now I don't plan to buy more than one until its price drops a little.
7) Message boards : Number crunching : Why different credits for same "long runs" ? (Message 40479)
Posted 14 days ago by Profile Retvari Zoltan*
hm, an unclearness came up with a recent "long runs" from Noelia: I finished "e10s4_e1s15f26-NOELIA_31x4-1-2-RND0004_1" within some 26 hours. In case of previous "long runs" by Gerard, for those I got 162.500 points credit, i.e. 131.250 + 25% for finishing within 48 hrs. For the task mentioned above, I got only 131.250, no extra bonus 25%. Why so?

You did receive the 25% bonus credit actually, but the base credits for this batch are 20% less than the Gerard's you've referenced.

As to why the server is marking the tasks as abandoned - nobody really knows, and I'd appreciate more help in tracking it down. It's done by the function mark_results_over(), which is called in two places in sched/handle_request.cpp (and nowhere else). It's supposed to happen "when there's evidence that the host has detached.", or "If the [RPC] seqno from the host is less than what we expect, the user must have copied the state file to a different host". But it seems to happen more than that, and the finger of suspicion seems to point at communication problems between host and server resulting in RPC requests being processed out of order on the server.

It happened on one of my dual boot (WinXP/Win7) hosts, when I've tried to make the BOINC manager use the same working folder on both OSes. I've succeeded to do it on my other similar host by setting the proper access rights for the BOINC work folder (which is located on the Win7's partition on this host), but on the first host the ongoing GPUGrid workunits gets abandoned, whenever I boot to Win7 (the BOINC working folder is located on the WinXP's partition on this host).

They all say for a status "Abandoned". That's so weird!

The root of this phenomenon should be some kind of BOINC work folder access rights problem.
Are there more than one user on this PC?
Is the BOINC installed as a system service (protected execution mode)?

That is ANCIENT.

That's true, but it still has to work under Windows 7 x64.
Until recently, I've used 6.10.60 on my hosts. The only reason for the update was to have such spare projects which are using OpenCL.

Please try the latest release, BOINC v7.4.36.

Updating to this version is still a good idea, as this will update the folder access rights.

I have twin GTX570's on water cooling and haven't gotten any new work in a couple weeks at least. IS there something going on here I haven't heard about?

Looking at your computer's detailed info, I see that the BOINC manager couldn't recognize the GPU (so called coprocessor) at all. It could be caused by that you've installed the BOINC manager as a system service (it's called "protected application execution" in the installer).
