We propose an implementation of the Conjugate Gradient
(CG) algorithm for real and complex, single and double precision arithmetics
suitable for serial, shared memory and distributed memory computers. For
the sake of simplicity, flexibility and efficiency, the CG solvers have
been implemented using the reverse communication mechanism for the matrix-vector
product, the preconditioning and the dot product computations. The code
is written in Fortran 77. Finally the implemented stopping criterion is
based on a normwise backward error.
