# Primes sample Parallel version of the Sieve of Eratosthenes. ## Building the example ``` cmake <path_to_example> cmake --build . ``` ## Running the sample ### Predefined make targets * `make run_primes` - executes the example with predefined parameters * `make perf_run_primes` - executes the example with suggested parameters to measure the oneTBB performance ### Application parameters Usage: ``` primes [n-of-threads=value] [number=value] [grain-size=value] [n-of-repeats=value] [silent] [-h] [n-of-threads [number [grain-size [n-of-repeats]]]] ``` * `-h` - prints the help for command line options. * `n-of-threads` - the number of threads to use; a range of the form low\[:high\], where low and optional high are non-negative integers or `auto` for a platform-specific default number. * `number` - the upper bound of range to search primes in, must be a positive integer. * `grain-size` - the optional grain size, must be a positive integer. * `n-of-repeats` - the number of the calculation repeats, must be a positive integer. * `silent` - no output except elapsed time.
