The Benchmark Tests' Details

Extensive discussion and various implementations of the HPCC tests are given elsewhere 6 7 8. However, for the sake of completeness, this section lists the most important facts pertaining to the HPCC tests' definitions.

All calculations use double precision floating-point numbers as described by the IEEE 754 standard 9 and no mixed precision calculations 10 are allowed. All the tests are designed so that they will run on an arbitrary number of processors (usually denoted as p). Figure 3 shows a more detailed definition of each of the seven tests included in HPCC. In addition, it is possible to run the tests in one of three testing scenarios to stress various hardware components of the system. The scenarios are shown in Figure 4.
