Hi,

Is it just me.... or is there a problem with the v2 client in 64bit linux ?

I`ve been running v2 on the same AMD64 hardware in32bit Mandrake, but when I switch to X86-64 Mandrake it segfaults as soon as it starts an iteration with v2.0 or v2.3. v1.25 is fine.

I`ve heard that it runs on Windows 64bit, so it could just be me.

Is there a way to switch off SSE2 on the AMD64 ?

john.

Since I do not have an AMD64 box, I really can't say anything as to why the Linux client doesn't run. I'm sure it has something to do with the way it was compiled, but I have no way to test it.

I've been running 2.3 on my Athlon64 (running Gentoo x86_64, 2.6.9 kernel) for some time now with no problems. My guess is that you're missing some 32-bit compatibility libraries, or that there's a bug in one of them. Have you had problems with other 32-bit binary apps in 64-bit Mandrake?

I mess something up when I built the 2.6.10 kernel.

It was failing after:
[Mon Jan 17 00:16:45 2005] got k and n from cache

but before:
[Mon Jan 17 00:16:45 2005] AMD Athlon(tm) 64 Processor 3200+ detected.

Every thing works fine with 2.6.8 kenel. Thanks anyway.

Something in the VM layout of the kernel changed in 2.6.10 64-bit kernel and sob along with prime95 will no longer work on it, previous versions of the kernel will work fine.

Has anyone reported this on mersenneforum.org (http://www.mersenneforum.org/)?

It`s true.

I built the same kernel from 2.6.9 source, and there`s no problem with that.

It seems to be fixed in kernel 2.6.11.10.

Just one of those things.
