The domain speedtest.net has been used to host a speed test since 2000, and was acquired by Ookla in 2006. [12] As of 2011, Ookla claimed 80% market share and was one of the top 1000 most popular websites. At the time, Ookla derived its revenue primarily from fees paid by companies to license custom speed test and proprietary testing software.
Measured at 62.86 gigaflops/watt, the smaller Frontier TDS (test and development system) topped the Green500 list for most efficient supercomputer [6] until it was dethroned in efficiency by the Flatiron Institute's Henri supercomputer in November 2022. [7] Frontier was superseded as the fastest supercomputer in the world by El Capitan in ...
SPEC was founded in 1988 and its membership comprises over 120 computer hardware and software vendors, educational institutions, research organizations, and government agencies internationally. SPEC benchmarks and tools are widely used to evaluate the performance of computer systems ; the test results are published on the SPEC website.
In June 2022, the United States' Frontier was the most powerful supercomputer on TOP500, reaching 1102 petaFlops (1.102 exaFlops) on the LINPACK benchmarks. [ 66 ] In November 2024, the United States’ El Capitan exascale supercomputer , hosted at the Lawrence Livermore National Laboratory in Livermore , displaced Frontier as the world's ...
A graphical demo running as a benchmark of the OGRE engine. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
The response time is the sum of three numbers: [3] Service time - How long it takes to do the work requested. Wait time - How long the request has to wait for requests queued ahead of it before it gets to run. Transmission time – How long it takes to move the request to the computer doing the work and the response back to the requestor.
The timed test is run on the system, and the time of the test system is compared to the reference time, and a ratio is computed. That ratio becomes the SPEC INT score for that test. (This differs from the rating in SPECINT2000, which multiplies the ratio by 100.)
HPE Frontier at the Oak Ridge Leadership Computing Facility is the world's first exascale supercomputer. Exascale computing refers to computing systems capable of calculating at least 10 18 IEEE 754 Double Precision (64-bit) operations (multiplications and/or additions) per second (exa FLOPS)"; [1] it is a measure of supercomputer performance.
