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.
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
