Enabling a proc under RedHat 3 AS and more...
 

Hi all, i need your help on this :

I had installed a 8 nodes cluster with Oscar 4.0
My servers are DL140 Proliant. The OS: RedHat 3 AS (kernel 2.4-21)
The installation was made with the hyperthreading enabled in the BIOS.
When i look /proc/cpuinfo i see then 4 procs, all is "normal"

The problem is that when i desactive the hyperthreading in the BIOS, the OS see 2 procs but it use one physical proc only(same physical id in /proc/cpuinfo), the other is desactivated ; it's desactivated 'cause when i type dmesg i see :
"enabling the CPU according to the ACPI table..." I don't know what it means..and later i see that on proc is divided and the other is desactivated...
In my kernel, hyperthreading is desactivated...

So the perf are poor, and it's for a calcul cluster!! ;-(

My question is: someone can explain this comportment to me?And how do i do to have my TWO physical procs activated.???

Thanks!!!!
