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
• make benchmark_primes - executes the example with suggested parameters to repeat performance measurements several times and report their relative error.
• make benchmark_primes_data - same as benchmark_primes saving results into benchmark_primes_data.csv file.

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; when it is greater than 1 then relative error will be calculated for them.
• silent - no output except elapsed time and relative errors.
