<DT>Parallel version of the Sieve of Eratosthenes.
|
|
<DT>The example can be built in the offload version to run on Intel® Many Integrated Core (Intel® MIC) Architecture based coprocessor (see <A HREF=../../index.html#build_4>build instructions</A>).

<DT><TT>primes [<I>n-of-threads</I>=value] [<I>number</I>=value] [<I>grain-size</I>=value] [<I>n-of-repeats</I>=value] [<I>silent</I>]</TT>

|
|
<DD><I>n-of-threads</I> is the number of threads to use; a range of the form <I>low</I>[:<I>high</I>], where low and optional high are non-negative integers or 'auto' for the TBB default.<BR>
|
|
<I>number</I> is an upper bound of range to search primes in, must be a positive integer.<BR>
|
|
<I>grain-size</I> is an optional grain size, must be a positive integer. <BR>
|
|
<I>n-of-repeats</I> is a number of the calculation repeats, must be a positive integer.<BR>
|
|
<I>silent</I> - no output except elapsed time.<BR>
|
|
|
|
<DT>To run a short version of this example, e.g., for use with Intel® Parallel Inspector:
|
|
<DD>Build a <I>debug</I> version of the example
|
|
(see the <A HREF=../../index.html#build>build directions</A>).
|
|
<BR>Run it with a small problem size and the desired number of threads, e.g., <TT>primes 4 100000</TT>.
