Hi, I recently joined this community. I added GPUGRID to my projects in BOINC (6.10.58) but I am experiencing several problems, and the forum on this site wont let me post because I have no credits yet... I will not have any credits because BOINC has been trying to get started with GPUGRID for over 3 days now without success...

How do I get help?

In the logs I see:

When creating a new post, the buttons that are hard to read, dark blue on black background, don't work when clicked.

if i highlight text and click B, URL, etc, nothing happens ?

They work on other projects on this same computer so i'm sure it's not me.

Our team has passed a milestone and achieved 2nd place here at GPUgrid.

team U.S.A. for Citizens, Friends and Patriots of the United States of America

Our flag: Stars and Strips or "Old Glory" - U.S.A. founded July 4th 1776

One of the long-standing traditions of distributed computing projects is the formation of teams.
Not just a tradition, a little healthy competition encourages active participation, to the general gain of the project.
Team USA was created to show we have American pride and that good ol' American know-how is still a reality.
If you're a patriotic American, this is the team to join. Embrace our motto of "United we stand".

DO NOT RUN 6.13.3 It has a major nasty bug.

A solution for this problem has been found:

David Anderson wrote:
There are (at least) two issues with 6.13.3:

1) For GPU apps, it passes an additional command-line argument that causes some apps to fail (usually by exiting immediately). This will be fixed in 6.13.4.

2) 6.13.3 handles file upload certificates (a mechanism that prevents DoS attacks on upload servers) differently than previous versions.
This change was necessary to make scheduler requests and replies readable by standard XML parsers. But it means that file uploads will fail to projects that a) use upload certificates, and b) aren't running current server code.

I sent email to boinc_projects describing this change, and recommending that projects disable upload certificates until they're able to upgrade their server code. Not all project admins read boinc_projects, so it may be necessary to contact them via their message boards or email, and I urge Alpha-testers to do so.

"Upload certificates" are a mechanism that keeps bad guys from DoS'ing your upload servers (note: such an attack has never happened, as far as I know).

We're changing the format of upload certificates, and we're starting to test a version of the client for which old-format certificates won't work. Volunteers testers won't be able to upload completed jobs, and they may complain to you.

I suggest that all projects disable upload certificates. To do so, add the following to your config.xml file:

<dont_generate_upload_certificates/>
<ignore_upload_certificates/>

To resume using upload certificates, if you wish:

1) upgrade to the current server source code (from trunk)
2) wait for all jobs with old-format certificates to be dispatched
3) re-enable certificates by removing the above lines.

Let me know if any questions.

Actually he does not need to go backwards in boinc version

What you want is the ignore gpu function. Replace 9 with the device number 0,1,2,etc as reported in boinc manager.

<ignore_ati_dev>9</ignore_ati_dev>
<!-- ignore (don't use) a specific ATI GPU. You can ignore more than one. -->
<!-- New in 6.10.19 -->

<ignore_nvidia_dev>9</ignore_nvidia_dev>
<!-- ignore (don't use) a specific NVIDIA GPU. You can ignore more than one. -->
<!-- New in 6.10.19 -->

That is the best you can do now, or just stop running GPUgrid altogether until the exclude_gpu function is finished and run all your gpus on another project that supports all your gpus fast and slow.

The new exclude_gpu function is not working yet as MarkJ pointed out, it MAY be working in 6.13.2 which has not been released nor tested yet.

In future versions, when this new function is working, you will be able to still run a project, like gpugrid on your fast gpu, but exclude it from your slower gpu but still allowing the slower gpu to krunch and run other projects it is capable of.

I have had same problem going on 45 days now.

It is not just a GPUgrid problem, but will happen on most any gpu project using cuda and a computer running dual cards, haven't seen problem on ati card but then i only have a sngle one in any system.

It appears only though to affect computers with twin cuda gpu's and as best i can tell this happens when switching apps, the new app loaded runs at 0%. Although i have not fully investigated this to be sure due to lack of time.

It also happens on different boinc versions, used 6.10.58 and 6.12.26 and had same problem on affected systems. NVIDIA driver upgrades also had no affect so far on problem.

I haven't seen problem on any of my single gpu systems, although all of those are 8800GT GPU's

I've had problem on two differnet systems both with twin GTX570's

Usually suspending the zero running app, will cause boinc to load a new gpu app and it runs fine, although the problem can reoccur next time, maybe, maybe not, an app switch occurs.

How was account creation disabled ?

I logged out, then whet to log in page. When I click on create an account I get a page not found ?

But all that does is hide that page. If the spammer is using a robot, it is sending the result of that page as a submit which your server is still processing, so yes they are still creating accounts.

I would suggest adding the captcha method of verification to create an account. Ya know those distorted letter words.

See http://en.wikipedia.org/wiki/CAPTCHA

Instructions for that had been included somewhere in boinc or the boinc wiki I think. maybe here http://boinc.berkeley.edu/trac/wiki/ProtectionFromSpam

Another simple trick would be to turn on the invitation code. Then post the invitation code in the instructions on the front page under, to create an account use invatation code 'GPUgrid' or something like that. I did this on my team's message board. It had the simple scrambled word graphic. This the robots could decode. So I made the word to be entered something different from what was displayed and posted it in plain text instruction under the entry box. This let humans in that could read but kept robots out because the robots were programmed to unscramle the word in the graphic and entered the word displayed next to the invitation code. A few humans could not get in because they too did not read and just automatically entered the word in the graphic, how programmed do we humans become. If you got the word wrong, I did a halt and this stopped 99% of the spammers from ever getting in.

I think the latest batch calls for IP blocking at the very least.

Even if the message database is scrubbed clean, all those random user accounts are going to be hanging around for years, clogging up the database.

Unfortunately that often has little effect. Spammers change ips as often as they post. They often too create virus type robots, the posts can be comming from someone's or more infected computers. If you block the ip, you could be blocking a legitimit user, that doesn't know they are infected of course.

I've reported it, and GDF was slow to get back to me, I don't think he took any steps yet as the spamming continues and now in a mass amount, and now the spammer(s) are posting every few seconds. I can't hide the posts that fast. I'll leave it up to GDF to clean up now and take measures to stop this.

Another thing too, if you block posting, like making a minimum of 1 credit, the spammers robots still create accounts. This attack is on a lot of boinc projects. There was a problem at MAlariaContol.net also. Something needs to be done to block registration, but then how do legitimate users get in ?
