MXV is a FORTRAN90 program which sets up several matrix vector multiplication problems y=A*x, and carries them out using
The user is allowed to specify M and N, the number of matrix rows and columns.

MXV is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
F90_INTRINSICS, FORTRAN90 programs which illustrate the use of FORTRAN90 intrinsic functions.
LINPACK_BENCH, a FORTRAN90 program which measures the time needed to factor and solve a "large" (N=1000) dense linear system of equations, and is used as a benchmark.
MATMUL, a FORTRAN90 program which is an interactive matrix multiplication benchmark program.
MDBNCH, a FORTRAN77 program which is a benchmark molecular simulation calculation.
MXM, a FORTRAN90 program which sets up a matrix multiplication problem A=B*C of arbitrary size, and compares the time required for IJK, IKJ, JIK, JKI, KIJ and KJI orderings of the loops.
MXV_OPENMP, a FORTRAN90 program which compares the performance of plain vanilla Fortran and the FORTRAN90 intrinsic routine MATMUL, for the matrix multiplication problem y=A*x, with and without parallelization by OpenMP.
NAS, a FORTRAN90 program which runs the NASA kernel benchmark.
SUM_MILLION, a FORTRAN90 program which sums the integers from 1 to 1,000,000, as a demonstration of how to rate a computer's speed;
TIMER, FORTRAN90 programs which demonstrate how to compute CPU time or elapsed time.
