Could not reproduce it with the latest MPICH. If the problem is not specific to MPICH, you'd better move your question to other forums like stackoverflow. $mpirun -n 2 ./test Matrix A : 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 Vector b before broadcast: 1.000000, 2.000000, 3.000000, 4.000000 Matrix A column : 4 after sending: lLim = 2 uLim = 4 for rank : 1 count = 8 Matrix A column : 0for rank = 1 after receive: lLim = 2 uLim = 4 for rank : 1 Ncol after broadcasting = 4 --Junchao Zhang On Mon, May 18, 2015 at 6:33 AM, Umesh Shisode <[email protected]> wrote:

Hello Sir / Madam,

This is Umesh Sharad Shisode, pursuing Masters in Modeling and Simulation, at Centre for Modeling and Simulation, Pune University. I am in the final stage of my course. My Masters Thesis title is :

Development of Conjugate Gradient solver in OpenFOAM / CPP using MPI

I am now doing MPI part of my project and facing some problems with MPI functions syntax. I am trying to use CPP class object with MPI functions but it is giving some error. Which I don't understand.

Operating system : LINUX Programming Language : CPP

Commands I am using are :

> mpic++ main.cpp -o result > mpirun -np 2 result

Please help me to sort out this issue . I am attaching herewith zip file containing the code which I want to parallelize with the png file containing error. Waiting for your reply. Thanks in advance.

Regards,
