| G-HPL ( system performance ) |
| HPL, Solves a randomly generated dense linear system of equations in double
floating-point precision (IEEE 64-bit) arithmetic
using MPI. The linear system matrix is stored in a two-dimensional block-cyclic
fashion and multiple variants of code
are provided for computational kernels and communication patterns.
The solution method is LU factorization through Gaussian elimination with
partial row pivoting followed by a backward substitution.
Unit: Tera Flops per Second

| G-PTRANS (A=A+B^T, MPI) ( system performance ) |
| PTRANS (A=A+B^T, MPI), Implements a parallel matrix transpose for two-dimensional block-cyclic
storage. It is an important benchmark
because it exercises the communications of the computer heavily on a realistic
problem where pairs of processors communicate
with each other simultaneously. It is a useful test of the total communications
capacity of the network.
Unit: Giga Bytes per Second

| Randomly Ordered Ring Bandwidth ( per process ) |
| Randomly Ordered Ring Bandwidth, reports bandwidth achieved in the ring
communication pattern. The communicating processes are ordered randomly in the
ring (with respect to the natural ordering of the MPI default communicator).
The result is averaged over various random assignments of processes in the
ring. Unit: Giga Bytes per second per process
