Subject: [OMPI users] Error in Binding MPI Process to a socket
From: vaibhav dutt (vaibhavsupersaiyan9_at_[hidden])

Hi,

I am trying to perform an experiment in which I can spawn 2 MPI processes,
one on each socket in a 4 core node
having 2 dual cores. I used the option "bind to socket" which mpirun for
that but I am getting an error like:

An attempt was made to bind a process to a specific hardware topology
mapping (e.g., binding to a socket) but the operating system does not
support such topology-aware actions. Talk to your local system
administrator to find out if your system can support topology-aware
functionality (e.g., Linux Kernels newer than v2.6.18).

Systems that do not support processor topology-aware functionality cannot
use "bind to socket" and other related functionality.

Can anybody please tell me what is this error about. Is there any other
option than "bind to socket"
that I can use.

Thanks.
