Hi Andy:
 
Not really sure what you mean...  are you saying that your nodes have 2 sockets but you are using only one?  cat /proc/cpuinfo should be giving you accurate information, so as far as your kernel is concerned, you do have 2 processors.
 
Possibilities...  you have dualcore CPUs (2 cores on each socket), or your chips support Hyper-Threading (you can disable this feature in BIOS if you want).
 
Cheers,
 
Bernard

Subject: RE: [Oscar-devel] Building oscar for FC4 x86_64 on EM64T

Hi Bernard,

In my previous installation for FC4 i386, the number of processors in my compute nodes was wrongly set to "-np=2". I guess it was done by  /opt/oscar/packages/torque/scripts/post_install
 
The reason is that the capacity of my compute nodes can have 2 processors, but I only have one on each of them. So
# cat /proc/cpuinfo | grep processor
processor       : 0
processor       : 1
I don't know how to modify the post_install script to read 0 or 1.
 
In fact, I can easily change the setting "-np=2" back to "-np=1" in  /var/spool/pbs/server_priv/nodes after the installation. But I would like it can be done automatically.
 
Thanks
Andy
