Looks like I was at least partly wrong in my interpretation of the results; the client isn't catching the signal. Anyway, using an older client shouldn't harm and might give some interesting insights anyway.
Can I change clients while I still have uncrunched results or does it do any harm?
th3: Thanks, didn't know there were Debian packages around somewhere else than in the repositories.
Well, I just changed... looks like most of my WUs survived intact and BOINC is crunching away happily. My benchmarks suck a bit, which is probably due to the older core client version. I remember that problem was around for quite a while. Since two out of my three projects give fixed credit I think I can live with that. Let's hope it helps Einstein a bit, I was unable to finish a WU successfully on this box for quite a while. I don't have an Einstein WU atm so it might take a while till we know.
Well, atm there seem to be some issues with 4.16; since we don't know where exactly they come from you can't be sure they won't affect you. So far, the problems seem to show mostly on Intel machines, but that might simply be because more people have Intel processors.
As for the need to change... I'm not sure if it will help much, performance-wise. I'm in this for the science and the technology involved ;-) if there is a new app that needs testing, I volunteer because I don't mind losing credit or having to invest some more effort if it helps the project. Also, I'm not really an inexperienced user by most standards which also helps. Therefore I volunteer to test apps which aren't quite ready for the general public, which is what beta testing is about.
Conan,
4.16 works perfectly fine on my Intel, i bet it would on your Opterons also, but its not quite as fast as 4.14, almost no difference but a tiny bit (at least it is on Core2), so no need to change unless you really really want to help with the testing.
I have been reading about the problems some people are having with App 4.16.
Is this App actually stable? and working now?
I am still running App 4.14 and it is working very well with no problems on my AMD Opterons with Linux (flavour Fedora Core 3 and 6).
I am trying to see the need to update to 4.16 if it is not better than 4.14.
I think I will wait till the next version comes out with more fixes.
About the time that 4.16 became available, I set up a new box with CentOS Linux. Since 4.16 was there, I went ahead and gave it a try. So far, it's run perfectly, with no issues.
The machine I set it up on is an SGI 1200 server with dual P-III 700's and 256 meg of memory. The OS is CentOS 5.
most of your tasks end up with exit code -185 and the message "Can't get shared memory segment name: can't get shared mem segment name". This is actually a message from the client and means that it couldn't set up a shared memory segment to communicate with the App. I don't know how to fix this, though.
When you fixed this, would you be willing to help us debug the "signal 11" problem in the App? The method of starting the DDD is the same I mentioned in my second post here, you would just need to type "cont" (or push the command toolbar button) once a new App is started and if it catches a signal 11, report the output (stackdump) here.
Well, I already tried to run 2 WUs under the debugger and after a bit of twiddling it seemed to work okay. But I think those WUs got killed by the error you mentioned, so it probably wasn't much good.
As for fixing the problem with the core client... wished I could. I even switched to the older client version th3 mentioned here, but to no avail. Now the problem has started to affect my other projects, too. Atm I consider completely uninstalling the package (--purge) and starting from scratch in case it's something with the setup...
I don't think it's related to the Client or the App. Have you started to use some new program recently that may make heavy use of shared memory resources? Have you upgraded (part of) your system recently that could affect shart memory management?
