TOP500 ranks the world's 500 fastest high-performance computers, as measured by the High Performance LINPACK (HPL) benchmark. Not all existing computers are ranked, either because they are ineligible (e.g., they cannot run the HPL benchmark) or because their owners have not submitted an HPL score (e.g., because they do not wish the size of their system to become public information, for defense ...
The actual performance will always be lower than the peak performance. [2] The performance of a computer is a complex issue that depends on many interconnected variables. The performance measured by the LINPACK benchmark consists of the number of 64-bit floating-point operations, generally additions and multiplications, a computer can perform ...
However, high performance computing applications written in Java have won benchmark competitions. In 2008, [74] and 2009, [75] [76] an Apache Hadoop (an open-source high performance computing project written in Java) based cluster was able to sort a terabyte and petabyte of integers the fastest. The hardware setup of the competing systems was ...
HPC Challenge Benchmark combines several benchmarks to test a number of independent attributes of the performance of high-performance computer (HPC) systems. The project has been co-sponsored by the DARPA High Productivity Computing Systems program, the United States Department of Energy and the National Science Foundation.
The Center for Advanced Computing and Modelling (CNRM) in Rijeka was established in 2010 and conducts multidisciplinary scientific research through the use of advanced high-performance solutions based on CPU and GPGPU server technologies and technologies for data storage. [37]
While early supercomputers used a few fast, closely packed processors that took advantage of local parallelism (e.g., pipelining and vector processing), in time the number of processors grew, and computing nodes could be placed further away, e.g., in a computer cluster, or could be geographically dispersed in grid computing.
Data-intensive computing systems utilize a machine-independent approach in which applications are expressed in terms of high-level operations on data, and the runtime system transparently controls the scheduling, execution, load balancing, communications, and movement of programs and data across the distributed computing cluster.

High-performance technical computing (HPTC) is the application of high performance computing (HPC) to technical, as opposed to business or scientific, problems (although the lines between the various disciplines are necessarily vague).
