[OMPI users] Core ids not coming properly

Hello Sir Here below is the code which I wrote using hwloc for getting the bindings of the processes. I tested this code on SDSC Gordon Super Computer which has Open MPI 1.4.3 and on TACC Stampede which uses intel's MPI library IMPI. With Open MPI I get all the core ids for all the processes as 0.

[OMPI users] Which type of collective call is called?

Hello Sir, In the implementation of MPI there are so many collective call implementations. I just want to when is the tuned collective calls called. What is it that I need to so that always tuned collective calls are called? Thank You -- Kranthi

[OMPI users] how to find the binding of each rank on the local machine

Hello Sir, I need a way to find out where each rank runs from inside the implementation? How do I know the binding of each rank in an MPI application? Thank You -- Kranthi

[OMPI users] Hi, I am working on topic "Topology aware mapping of processes in intra node environment". I need to find the binding of each rank on the local machine. How do I do this? I am using OPENM

Hi, I am working on topic "Topology aware mapping of processes in intra node environment". I need to find the binding of each rank on the local machine. How do I do this? I am using OPENMPI version 1.4.1 Thank You -- Kranthi
