SUM_MILLION is a FORTRAN77 program which sums the numbers from 1 to 1,000,000, times the comutation, and computes the corresponding MegaFLOPS rate.
sum_million runs the program.

LINPACK_BENCH, a FORTRAN77 program which measures the time needed to factor and solve a linear system.
MATMUL, a FORTRAN77 program which is an interactive matrix multiplication benchmark program.
MDBNCH, a FORTRAN77 program which is a benchmark code for a molecular dynamics calculation.
MEMORY_TEST, a FORTRAN90 program which declares and uses a sequence of larger and larger vectors, to see how big a vector can be used on a given machine and compiler.
MXM, a FORTRAN77 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, 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.
