Michael, do you have an estimate for the memory footprint of a single task? I'm wondering if the larger cache sizes of the E5 Xeons might be used to huge advantage by fitting just a single task in their 20+MB cache and avoiding memory accesses entirely.

Installed BOINC 6.10.58 and it works without any missing package dependencies.

Thanks for the helpful replies. Unfortunately the BOINC version available for download from this site has some library incompatibilities.

./run_manager
./boincmgr: error while loading shared libraries: libwx_gtk2u_html-2.8.so.0: cannot open shared object file: No such file or directory

I installed a few libraries like wxwidgets but I can't find gtk2 in the package manager so more research will be needed to get it running.

Too bad, the BOINC version I already had was working fine with WCG.

Neither does your reply.
Tell me what information you need that I haven't already provided.
My mistake, it's Ubuntu 12.04 LTS.

I'm trying to get set up for the Olympics challenge. I have an i7 system running Ubuntu 11.10 64-bit. Each time it downloads a new work unit it fails immediately. Task status simply shows "computation error". Looking at the log file time stamps, it does not appear to actually be downloading anything. I have a fairly slow internet connection and if the client is really 35MB as stated it should take at least a minute, not just a few seconds.

7) Message boards : Number crunching : The Marie Sophie Germain Challenge 2012 (Message 52470)
Posted 2813 days ago by Punchy
Well, I woke up to my fast system running 0 tasks with 1 download pending with a 10 minute retry delay. The client-server logic seems to be broken for machines where all tasks can be completed within 15 minutes. One download timeout appears to block any further downloads from being requested; looking in the logs I see that completed work was uploaded during that timeout, 20+ threads idle, "not requesting new work". Even when I retry the download and it completes, it only requests 4 more tasks even though 32 threads are idle. So, on this system, I'll be completing a few tasks every 15 minutes, with about 10 minutes of completely idle time during that 15 minute period.

I don't know what the server issue is, but I keep finding my fastest system only running 2-6 tasks on a 32-core system, with the rest of the downloads in a 15-minute backoff. Increasing the work buffer doesn't seem to help. I get the message that internet connection is fine but unable to connect to servers. Very frustrating.

As for the Evga team, great job and I'm just glad we don't have much longer to go. Is this an indication of another team in the mix of horde and herd?



Thanks, we are pretty new to the challenge world and somewhat slow starters, but next time we should be more prepared. Extend this challenge for 48 hours and we might have a chance. Somehow roast rat just isn't the motivator that roast beef was. ;-)
