Excellent news Eric!

I look forward to putting a few computers to good use.

Message 21920 - Posted: 3 Mar 2010, 16:52:29 UTC - in response to Message 21918.  

I thought it had been updated! and that was why we couldn\'t run anymore. What I can I tell QMC who are managing the server?

Ah. Well first of all, don\'t get cross with them at my say-so: I have literally zero experience running a BOINC server, so take my advice with a grain of salt.

However, if you check the Server Status page, you will see it lists the Server software version as 15379. This changeset, pushed on the 9th of June 2008, was never marked as stable, and ironically the very next stable release, changeset 15398, was supposed to fix handling of quotes and slashes for the forum software. The most recent version is changeset 20149, and you can find a history of major changes for all changesets on this page.

To summarize: the server software you\'re currently running is not a stable release, and is almost two years old. I recommend getting them to update to the latest version, but be aware that there have been major changes since 2008, and the update may not be a simple one (according to the ServerUpdates page I linked to above, two of the updates require a database update, and this process was only automated in changeset 16160, which the current version predates).

I also hope QMC will get the server upgrade too, but right
now we have a service to be proud of thanks
to all volunteers.


Tnx 2 you - it works :)

Absolutely! Reading both on and between the lines it seems that lhc@home might have died an ignominious death without Eric\'s efforts.

Three cheers, that man! :D

Message 21994 - Posted: 7 Mar 2010, 23:14:30 UTC

To Eric:
When I try to press \"Show graphics\" button, BOINC interrupts its calculations with the message \"Permanent upload error\". The same thing happens when my computer (Win7) comes into screen saver mode and automatically starts to show BOINC\'s graphics. Why?

It’s a known problem. Read the Computation Error thread in the Number Crunching forum.

Thanks a lot. I\\\'ve already switched off the screen saver.

As mentioned in the other thread, it is a known issue and we are trying to implement a solution.

Dear All;
The following questions are open:

why don\'t you do a survey?
on the forum or via mail.
this could make clear which are the most importent problems.

Never thought of that; I am hoping to get the feedback from
the server side. That would quantify the problems we are
having. We are already getting feedback on the Message Boards. I\\\'ll bear it in mind. Eric.

The LHC@home database/server should answer pretty much all those questions we\'re trying to pull them out at the moment.

Message 22077 - Posted: 15 Mar 2010, 11:23:28 UTC - in response to Message 22072.  

The present
build for Windoes involves application code generation on
Linux, moving it and makefile to Windows via CYGWIN. building
the crlibm on cygwin, importing the objects to a Windows .NET (2003Version ONLY..) and then a build.

Ouch - is there any chance you could migrate to MinGW? (perhaps with the version of GCC offered here until the update to GCC 4.5.0 is finalized)
If the client graphics get in the way of such a switch, I\'d just tear them out for now until the code becomes more manageable.. I know some will complain, but I don\'t think a lack of volunteers is the problem here ;)

Message 22091 - Posted: 18 Mar 2010, 6:32:31 UTC

Good day to all
it so happens that I downloded wu\\\\\\\'s several times, but all of them crashed immediately at the moment I wanted to have a look at the graphics.

Yesterday I tried agn and the file came in with an expected timespan of some 3 hours. I let it run for about 5 hours and during that time the file counted up to some 8 hours and had clocked some 3 pct of work done.

I checked on the graphics and the wu immediately crashed agn.

I have a reasonably modern machine running 2.5 gigahertz under Vista and I pretty rarely experience such crashes when doing other projects.

What is is going wrong?

Best regards Lugal

The graphics are currently broken. Please disable the screensaver, if you use it, and do not attempt to open the graphics manually. Hopefully this will be fixed soon, but we might lose graphics altogether for a while.
