- -- Abstract :
- -- PIWG is a suite of tests/benchmarks prepared by the
- -- Performance Issues Working Group of ACM SIGAda. The purpose of
- -- PIWG is to develop the benchmarks and collect and disseminate results.
- -- The PIWG tests have been under development for many years and
- -- have been run against many Ada compilers. The PIWG test suite
- -- contains over 190 files which include Whetstone (to measure
- -- processor speed), Dhrystone (to measure statement execution per
- -- unit time), and other benchmarks which test various attributes of
- -- the Ada language and their implementations under specific
- -- compilers. The PIWG tests must be customized for a particular
- -- compiler, and instructions are included to do this.
- -- Some of the items measured by PIWG include:
- -- * task creation-related timing
- -- * dynamic elaboration-related timing
- -- * exception-related timing
- -- * coding style-related timing
- -- * TEXT_IO-related timing
- -- * loop overhead-related timing
- -- * procedure call-related timing
- -- * task-related timing
- -- * compilation, link, and execution times
