I just received two work units. When I clicked om the \"Show Graphics\" button, the job terminated at once with \"Computation error\". I (unfortunately) tried this button on bothe work units, with the same result.

I did exactly the same, clicking on \\\"show graphics\\\", after more than 3 hours ruuning of a LHC WU.
So got one WU finaly and now killed it myself...by a simple click.

Me too, this newbie coding had the following effects:

- killed the WU
- killed the boinc client
- killed the boinc manager

Not even a system restart could fix it and make BOINC run again.

I received the following messages when forcing boinc.exe to load:



I had to delete the whole LHC directory to make it work again...

Thank you very much!

It looks like - SCREEN SAVER IS KILLING THE TASKS!
No matter, is Show Graphics clicked or not.
6 of 7 tasks crushed, sad.

---Update---
SOS!!!
Unfortunately...
If Windows screen saver is set to BOINC, all the tasks are dying.
This effect appears at least on all machines with ATI video cards. No matter, which model. New or, for example, 3+ years old.

New rule for LHC@home - avoid Show Graphics.

We are referring to (Show graphics) in the tasks list while the task is running, not posts on the message board ;-)

By the way, your account name means (What next).

In fact, whats the point of a graphic other than complicating the code? Feel free to leave it out. It takes away from the crunching anyways.

I just got my first 2 WU’s 10 months to the day from the last LHC WU’s that I completed. The first one got a computational error 3 minutes into it. It may be just a coincidence, but the error occurred at the exact moment that the screen saver kicked in. The next WU started up immediately after and it ran to completion in about 10 minutes. This time I was actively using the computer the whole time so the screen saver never kicked in. So it seems that the screen saver is causing problems.

Happened to me too. Signed up in August and they were the first projects I got - and like within a minute of completing. It\'s a brand new computer (my old one died last week) so the video card shouldn\'t need updating. There are 4 more WU\'s lined up luckilly and they only take about 45 minutes.

This happened to me too. Too bad I liked the screensaver. :(

Like others, I recommend they just tear it out until they get a chance to fix it. The screensaver is nice, but like this there\'s no point in it.

I hope, this bug is not difficult to find and to fix.
And I hope, the project team is reading our messages.

Seen it, knew the graphics would bite us in the ass eventually. They were way too pretty.

We have been considering killing the graphics as they are a stumbling block when compiling. I'll pester bigmac and Alex.

It\'s not just a question of not clicking on the show graphics. If you use BOINC screen saver and it happens to have a LHC unit running it will still kill the work unit. Makes no difference if it\'s an ATI or NVidia Card.

To be honest if you take out the screen saver permanently, I and many others won\'t be doing crunching for LHC. The cool screensaver was what got my attention to start with.

About 50% of the projects now on BOINC have the screensaver and it\'s a great tool for getting others interested in a project. I waited with a dead LHC all last year because it was the best screen saver on BOINC. Unfortunately LHC went dead of all work shortly after I started. And I anticipated it\'s return to functionality so I could put my quad cores to using it.

Power crunchers don\\\'t have to run the BOINC screensavers if they don\'t want to. But I wish they would stop making comments about removing it like it\'s getting in the way of their processing. It\'s not. Just because you don\'t want it doesn\'t mean all others feel the same. A large percentage of the BOINC community (myself included) choose projects based on the screensavers. Take it out temporarily if you need to get units working. But it needs to be fixed not ripped out permanently. If you don\'t want to run it, don\'t turn on the screen saver. But don\'t take the functionality of the screen saver away from those of us who do use it. I personally could care less if it slows the progress of the work units I run. I and many others do BOINC for the screensavers occupying what would otherwise be a bland desktop. We could have the screensavers and those who don\'t want it could just not run it. We can have the best of both worlds. No need to bash those who like the screensavers.

Personally, I have no intention to shut down the screen saver for all the other projects whose screensavers play together just fine just because LHC’s doesn’t. So unless the goal of this project is to see how many errored out WU’s a participant can tolerate before dumping the project, I think this problem should get fixed.

Two workunits received today but were not completed due to error reported by file upload server: nbytes missing or negative.
