MXM is a FORTRAN77 program which sets up a matrix-matrix multiplication problem A = B * C, and carries it out using
The user is allowed to specify N1, N2, and N3, which define the matrix sizes.

LINPACK_BENCH, a FORTRAN77 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 FORTRAN77 program which is an interactive matrix multiplication benchmark program.
MDBNCH, a FORTRAN77 program which is a benchmark molecular simulation calculation.
MXV, a FORTRAN77 program which compares the performance of (DO I, DO J) loops, (DO J, DO I ) loops, and MATMUL for computing the product of an MxN matrix A and an N vector X.
SUM_MILLION, a FORTRAN77 program which sums the integers from 1 to 1,000,000, as a demonstration of how to rate a computer's speed;
