Building ReproBiCGSTAB

1. clone the git-repository into

2. inside the src directory, invoke make to create CG_MPI executable

Example

automatically generated matrix arising from the finite-difference method of a 3D Poisson’s equation with 27 stencil points. This matrix has the number of rows/columns of the matrix equal to 256^3.

mpirun -np P --bind-to core ./ReproBiCGSTAB/src/CG_MPI ../Matrices/$mat 0 2 159 27

matrix from the Suite Sparse Matrix Collection

mpirun -np P --bind-to core ./ReproBiCGSTAB/src/CG_MPI MAT.rb 1
