Manufacturer/Processor Type, Speed, Count, Threads, Processes
Includes the manufacturer/processor type, processor speed, number of processors, threads, and number of processes.
Move mouse over this column for each row to display additional information, including; manufacturer, system name, interconnect, MPI, affiliation, and submission date.

Computer System
Name and version of Message Passing Interface (MPI) implementation.

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
EP-DGEMM ( per process )
Embarrassingly Parallel 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 in embarrassingly parallel manner - all computational processes perform the benchmark at the same time, the arithmetic average rate is reported. Unit: Giga Flops per Second
EP-STREAM ( per process )
The Embarrassingly Parallel 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 in embarrassingly parallel manner - all computational processes perform the benchmark at the same time, the average is computed. Unit: Giga Bytes per Second
EP-RandomAccess ( per process )
Embarrassingly Parallel Random Access - (also called GUPs), measures the rate at which the computer can update pseudo-random locations of its memory. The embarrassingly parallel version runs the code locally on each processor. No explicit communication is performed (but shared-memory effects might occur). Unit: Giga Updates per Second
EP-FFTE ( per process )
Embarrassingly Parallel FFTE, performs the same test as FFT but in embarrassingly parallel fashion - the code is run locally on each processor. No explicit communication is performed (but shared-memory effects might occur). Unit: Giga Flops per Second
