Hi,

          I've a CentOS-5.8 Linux installed on a server which has the Intel
Xeon Sandy bridge 8 core, dual socket processor. As Sandybridge has AVX
feature and can do 8 flops. But  we're not able to take performance boost
of AVX , as this feature not supported on CentOS-5.8.

          Is it possible to get AVX working, by just installing the
CentOS-6.0 or 6.2 kernel on existing CentOS-5.8 OS, instead of doing
re-installation with CentOS-6.2?

          We're even ready for compiling kernel source.

           Let us know what you suggest on this.


Thanks in advance
