This is the first native 64Bit (Linux) App of Einstein@Home. It's mainly meant to test compatibility. It was built on a Ubuntu 6.06 system from the same codebase as the 1.07 Linux App, I don't expect any differene e.g. in runtime. Its main purpose is to relieve participants from having to install the 32Bit compatibility libraries on 64Bit stsyems.

Thanks for building this app for Linux. Does the app download automatically on 64-bit systems or should it be downloaded manually and setup via an app_info.xml file?

The app appears on the public applications page, so it should download automatically on appropriate platforms. If one of Bernd's tests requires an app_info.xml, he usually posts the whole thing in the beta area for manual download.

It should get downloaded automatically with a 64Bit Linux Client that reports the correct platform (x86_64-pc-linux-gnu). Many Linux distributions, though, only have a 32Bit BOINC Client or report a different platform (I think SuSE uses x86_64-unknown-linux-gnu).

I just checked, and it appears that all of my 64-bit Linux machines are still getting the 32-bit apps. That includes CentOS, Fedora, OpenSuSE, and Arch Linux. All except for one OpenSuSE machine are running with 64-bit BOINC.

What platforms do these

What platforms do these Clients report to the scheduler? Try something like:

grep -C1 platform sched_request_einstein.phys.uwm.edu.xml

For the 64-bit Ubuntu 8.04 machine, I get this:

1
    x86_64-pc-linux-gnu
    
        i686-pc-linux-gnu
    
    
--
    5
    i686-pc-linux-gnu
    107

This one is from the 64-bit CentOS 5.5 machine:

1
    x86_64-pc-linux-gnu
    
        i686-pc-linux-gnu
    
    
--
    5
    i686-pc-linux-gnu
    107

For the 64-bit Arch Linux machine:

1
    x86_64-pc-linux-gnu
    
        i686-pc-linux-gnu
    
    

I almost forgot about the 64-bit Debian 5.0 machine:

 1
    x86_64-pc-linux-gnu
    
        i686-pc-linux-gnu
    
    
--
    5
    i686-pc-linux-gnu
    107
--
    5
    i686-pc-linux-gnu
    107

From a 64-bit Fedora machine:

1
    x86_64-pc-linux-gnu
    
        i686-pc-linux-gnu
    
    
--
    5
    i686-pc-linux-gnu
    107

Thanks. This is weird. I

Thanks. This is weird. I can't imagine that the clients need to be restarted, but it might be worth a try.

It might be that the current plan-class settings make scheduler think the x86 SSE2 App runs faster on these machines than the native x64 App. I won't have time to look into that over the weekend, though.

Well, I have one Fedora machine that needs to be re-booted anyway. I'll go ahead and do that now to see what happens.

I reconfigured the scheduler.

I reconfigured the scheduler. Please have another try and update the project.

Edit: sorry, probably won't help. The scheduler code we're using is too old. May need to backport from recent BOINC code or implement a new plan class to work around the problem.

I added a fake 64 Bit plan

I added a fake 64 Bit plan class (X8664), should work now.
