The goal of this benchmark is to measure the performance of Intel CPU, by solving dozens of mathematical equation - Linear equation - measured in FLOPS unit, such as GFlop/s or TFlops. The MKL benchmark and developer guide can be found here.
What is the linpack benchmark download#
Both Window and Linux users can download the Intel's High Performance LINPACK (HPL), called Intel Optimize LINPACK Benchmark and Intel Distribution for LINPACK Benchmark from the Intel Math Kernel Library (MKL). LINPACK has been mostly used to test the supercomputer, whose best performance was compared and ranked by TOP500, the most famous HPC benchmark ranking website. It was written in Fortran by Jack Dongarra.
What is the linpack benchmark software#
LINPACK is a software library for performing numerical linear algebra on digital computers. To do so, one can use this LINPACK for benchmarking your own PC/Cluster/Supercomputer or whatever that made of CPUs as processor.
What is the linpack benchmark how to#
Do you know how to know the best performance of computer? Have you ever wanted to evaluate the speed/performance of your CPU and compared its power to others? This post will explain you step-by-step how to benchmark or test the performance of your machine!. Our simulation allows us to hint where the main algorithmic improvements must have been done in HPL.TOP500 project ranks and details the 500 most powerful non-distributed computer systems in the world. Such performance reveals much lower than what was reported and which was obtained using a closed-source version specifically designed by the Intel engineers. Allied to a careful modeling of Stampede, this simulation allows us to evaluate the performance that would have been obtained using the freely available version of HPL. While this qualification run required the dedication of 6,006 computing nodes of the supercomputer and more than 120 TB of RAM for more than 2 hours, we manage to simulate a similar configuration on a commodity computer with 19 GB of RAM in about 62 hours. More precisely, we take as a motivating use case the large-scale run performed on the Stampede cluster at TACC in 2013, when it got ranked 6th in the TOP500.
What is the linpack benchmark simulator#
In this article, we explain how we both extended the SimGrid's SMPI simulator and slightly modified HPL to allow a fast emulation of HPL on a single commodity computer at the scale of a supercomputer. Such optimization can be particularly time consuming and can hardly be done through simple mathematical performance models. With core-counts beyond the 100,000 cores threshold being common and sometimes even ranging into the millions, an optimization of HPL parameters (problem size, grid arrangement, granularity, collective operation algorithms, etc.) specifically suited to the network topology and performance is essential. With a power consumption of several MW per hour on a TOP500 machine, test-running HPL on the whole machine for hours is extremely expensive.
