  2. Hardware performance counter - Wikipedia

    en.wikipedia.org/wiki/Hardware_performance_counter

    Compared to software profilers, hardware counters provide low-overhead access to a wealth of detailed performance information related to CPU's functional units, caches and main memory etc. Another benefit of using them is that no source code modifications are needed in general.

  3. HPC Challenge Benchmark - Wikipedia

    en.wikipedia.org/wiki/HPC_Challenge_Benchmark

    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 .

  4. Testing high-performance computing applications - Wikipedia

    en.wikipedia.org/wiki/Testing_high-performance...

    The number of test cases per input data set is: n C 1 + n C 1 + … + n C 1 = 2 n-1 Where n = total number of synchronization, process creation and communication calls. This equation has exponential order. In order to reduce the number of test cases, either Deterministic Execution Method (DET) or Multiple Execution Technique (MET) is used ...

  6. High-performance computing - Wikipedia

    en.wikipedia.org/wiki/High-performance_computing

    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 ...
