Rosetta@home getting computation errors on new Ubuntu 10.10 install.

[CrimsonWolf]

I just resurrected an old pile of computer parts and put on Ubuntu 10.10 64-bit to try out Linux.

One of the first things I tried was installing Boinc so the computer could work on Rosetta@home. After installing it, I attached Rosetta, it pulled down a couple work units and started working on them, so all seemed well. But every single one ran briefly and then ended with a computation error. 😕

Between running a couple passes of memtest86+ and the computer otherwise being completely stable, the hardware seems fine. Then, I attached Milkyway@home and the exact same thing happened. So I'm convinced something is wrong with my install of Boinc and/or how these projects run on the computer.

It has a Core 2 Duo E6600, 4 GB of RAM, a GTX 275 video card (not trying to use it for DC right now - the WUs are CPU only). It's Ubuntu 10.10 64-bit and I ran all the updates in the update manager.

Googling gave mixed results. Could it be a 64-bit versus 32-bit issue since I have a 64-bit install? Any ideas on how to get it working? I'm a complete noob at Linux right now, so any help would be much appreciated.

EDIT: I installed Boinc according to the directions here. https://wiki.edubuntu.org/BOINC

That is certainly a possibility. Have you attempted to install the 64 bit version of the BOINC software for Ubuntu?

I would try that first. The few times that I installed BOINC on a *nix computer, I never ran into any troubles (other than when you had to update the software every so often). Usually I just uninstall and install the newest version.

Hmm... not sure, I need to check when I get home. It's whatever the "sudo apt-get install boinc-client boinc-manager" command would install.

I looked at the above website again and found something that might help. It was down in the Ubuntu server section so I didn't see it earlier. "If you are running 64 bit Linux and 64 bit BOINC then you might have a problem with projects that issue 32 bit applications rather than 64 bit applications. To allow 32 bit applications to run on 64 bit Linux you must install 32 bit versions of certain shared libraries (as explained here)"

I'm pretty sure Rosetta@home is 32-bit only. IIRC, it has an asterisk next to the processes on my Windows x64 computers. So that seems to make sense. It pointed me to this website (http://boinc.berkeley.edu/wiki/Installing_on_Linux#64_Bit_Considerations) and lists some packages to install for Ubuntu. And looking at this website again, yeah 64-bit Ubuntu installs 64-bit Boinc.

Anyway, I'll give that a try later tonight and check back in.

That's an interesting bit of information. As far as I know of, R@H was also a 64-bit application (besides the BOINC software itself). Nonetheless let us know where your lead gets you. I'm curious myself, as I will eventually moved to *nix and other OSS.

Success! It's been churning out work units all day without a hitch. That must have done it. I took 32-bit support for granted. I just checked on a Windows 7 computer and they're indeed running as 32-bit processes, so I'm guessing the linux apps are the same.
