SEARCH_SERIAL is a C program which searches integers between A and B for a value J such that F(J) = C.
For the particular example considered here, the solution will be F(1,674,924,981) = 45.
This program is intended as a starting point; both MPI and OpenMP can be used to make a parallel version.

SEARCH_SERIAL is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version and a PYTHON version.
FFT_SERIAL, a C program which demonstrates the computation of a Fast Fourier Transform, and is intended as a starting point for developing a parallel version using OpenMP.
FIRE_SERIAL, a C program which simulates a forest fire over a rectangular array of trees, starting at a single random location. It is intended as a starting point for the development of a parallel version.
HEATED_PLATE, a C program which solves the steady state heat equation in a 2D rectangular region, and is intended as a starting point for implementing an OpenMP parallel version.
IS_SERIAL, a C program which a serial version of the Integer Sort (IS) NAS Parallel Benchmark, which is intended as the starting point for the development of a parallel version.
LIFE_SERIAL, a C program which computes a few steps of the evolution of John Conway's Game of Life, intended as a starting point for implementing a parallel version.

QUAD_SERIAL, a C program which approximates an integral using a quadrature rule, and is intended as a starting point for parallelization exercises.
SEARCH_MPI, a C program which searches integers between A and B for a value J such that F(J) = C, using MPI for parallel execution.
SUBSET_SUM_SERIAL, a C program which seeks solutions of the subset sum problem, in which it is desired to find a subset of a set of integers which has a given sum; this version of the program is intended as a starting point for a parallel approach.
