Does the operating system itself recognise and use the second core? If not, Boinc won\'t be able to do any better, regardless of what the various configuration files say.

Try updating the Bios if this is the case.

PS. Funny how few people read my post carefully. :-)

I think the reason people weren\'t sure about the processors is that you didn\'t actually say what the new processor was in your original post :-)

I\'m not positive, but I THINK that 5.8.16 has the local configuration over-ride file, whatever it\'s called. If so, then it may have picked up the \"On multiprocessors, use at most\" setting of 1 from the old BOINC folder.

If the file exists, you can either edit it, or use \"Clear\" in the Manager (somewhere) to remove the lot.
Then BOINC should follow what you have set in preferences on the server.

But it could be something else. BOINC is getting far too complex for it\'s own good.

5.8.17 was built with a newer compiler version and uses versions of glibc and stdc++ that might not be available on some older distributions.

You should be able to run 5.8.16 - here are the download links:

5.8.16 release version

5.8.16 debug version

There were problems last week with several things, and Carl was out of town. He got back in to town, fixed what he could on Friday, and now it\'s the weekend. Monday morning is 15-16 hours away. That\'s just when they start getting in. Give them some hour after to work on things.

People need to understand these people do not work 24/7.

The only thing that has changed recently, is the arrival of a new trickle server, and an extended shutdown to allow one of the servers to re-do a database.

I still think a 64 bit executable would speed things up significantly. Sixteen registers plus SSE3 ought to make a real difference.

I agree, and it does speed things up considerably (based in testing on sulphur alpha 6-7 months ago), but there is now some concern that the results may be different enough in 64bit compared to 32bit that it might screw up model comparisons. Then there may also be automated distribution problems where BOINC has to be smart enough to download the right hadsm executable based on whether a PC is running a 64bit OS or not. But I don\'t know if BOINC can do that.

Another possible slowdown in your system...

If this is a socket754 3200+, and you have a Via chipset motherboard, it may be that the memory is running at 333 MHz instead of 400 MHz. Some Via chipset motherboards would automatically decrease memory speed to 333 MHz if 1 GB or more of memory was installed. CPDN is highly dependent on memory bandwidth and latency and anything that slows that down, also slows CPDN down.

There\'s something wrong with that performance. With a 3200+ (socket 754) in 64bit Fedora Core 3, mine ran at about 3.45 to 3.5 s/TS, which was only very slightly slower than WinXP 32bit on the same PC. Something else is going on there. Is the screensaver set to blank? Is cool n quiet off? Are you running the graphics much?
