| Run Type |
|
Run Type, indicates whether the benchmark was a base run or was optimized. |
| Processors |
|
Processors, this is the number of processors used in the benchmark, entered in the form by the benchmark submitter. |
| 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 |
| S-DGEMM ( single MPI process ) |
| Single MPI Process DGEMM, benchmark measures the floating-point execution rate of double precision real matrix-matrix multiply performed by the DGEMM subroutine from the BLAS (Basic Linear Algebra Subprograms). It is run on single computational process chosen at random. Unit: Giga Flops per Second |
| S-STREAM ( single MPI process ) |
| The Single MPI Process STREAM benchmark is a simple synthetic benchmark program that measures sustainable memory bandwidth and the corresponding computation rate for simple vector kernels. It is run on single computational chosen at random. Unit: Giga Bytes per Second |
| S-Random Access ( single MPI process ) |
| Single MPI process Random Access - ( also called GUPs ), measures the rate at which the computer can update pseudo-random locations of its memory. The single CPU version runs the code locally on a randomly chosen processor. No explicit communication is performed and so the performance of the local memory subsystem is revealed. Unit: Giga Updates per Second |
| S-FFT ( single MPI process ) |
| Single MPI process FFT, measures the floating point rate of execution of double precision complex one-dimensional Discrete Fourier Tranform (DFT). The vector size is a power of two. Unit: Giga Flops per Second |
