Wrong arch?

Post by zmcjr »

Hi!
The x86 version of FahCore_a3 downloaded has the wrong arch: x86_64.
/var/lib/fahclient/cores/www.stanford.edu/~pande/Linux/x86/Core_a3.fah$ file FahCore_a3
FahCore_a3: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped
Error log:

Is there a better place/thread to write this?

Thanks!

Welcome to the F@H Forum zmcjr,

Can you please tell us what Linux version you are using? Also, please post the initial section of the log which contains your system details and F@H configuration.

Also, I have moved your thread to a more appropriate forum.

Back when the a3 SMP core for linux was released, a 64 bit arch (and OS) was required for SMP folding. It is unlikely they ever made a 32 bit version. Both of the a3 files are dated 2011, so it's unlikely they changed anything since then.

Some additional background information that may or may not interest you:

Do you run a 32-bit OS because your hardware is limited or out of convenience?

The Windows version of FahCore_a3 is 32-bit. Back in 2011, a significant number of Donors had 32-bit Windows systems. Virtually all Linux users had "big" systems with 64-bit hardware although some were running a 32-bit OS. Upgrading to a 64-bit OS was considered a pretty simple process.

As 7im suggests, it's not likely to change. In fact, we get requests for a 64-bit version of FahCore_xx for Windows because people mistakenly believe that would give Windows a major speed improvement. In fact, bigadv assignments (FahCore_a5) needs access to more memory than a 32-bit FahCore can accommodate, which is one reason bigadv is limited to Linux.

I am using slackware linux 13.37, kernel 3.10.7.

I thought this was wrong as the url says x86 and downloaded program is 64bit.

I will plan to install a 64 bit system.

Thank you all!
