Pi Sample
Parallel version of calculating π by numerical integration.
Build
To build the sample, run the following commands:
cmake <path_to_example>
cmake --build .
Run
Predefined Make Targets
make run_pi- executes the example with predefined parametersmake perf_run_pi- executes the example with suggested parameters to measure the oneTBB performance
Application Parameters
You can use the following application parameters:
pi [n-of-threads=value] [n-of-intervals=value] [silent] [-h] [n-of-threads [n-of-intervals]]
-h- prints the help for command-line options.n-of-threads- the number of threads to use. This number is specified in the low[:high] range format, where bothlowand, optionally,highare non-negative integers. You can also useautoto let the system choose a default number of threads suitable for the platform.n-of-intervals- the number of intervals to subdivide into. Must be a positive integer.silent- no output except the elapsed time.
