There are a small number of performance tuning options that are determined
|
|
by configuration macros. These should be set in boost/math/tools/user.hpp;
|
|
or else reported to the Boost-development mailing list so that the appropriate
|
|
option for a given compiler and OS platform can be set automatically in our
|
|
configuration setup.

Many of the coefficients to the polynomials and rational functions
|
|
used by this library are integers. Normally these are stored as tables
|
|
as integers, but if mixed integer / floating point arithmetic is
|
|
much slower than regular floating point arithmetic then they can
|
|
be stored as tables of floating point values instead. If mixed arithmetic
|
|
is slow then add:
|
|
</p>
|

<div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
|

define BOOST_MATH_INT_TABLE_TYPE(RT, IT) RT

permits two operations to occur in parallel for polynomials, and

four in parallel for rational functions. This differs from method

"2" in that the code is carefully ordered to make the parallelisation

more obvious to the compiler: rather than relying on the compiler's

optimiser to spot the parallelisation opportunities. This only occurs

The performance test suite generates a report for your particular compiler
|
|
showing which method is likely to work best, the following tables show the
|
|
results for MSVC-14.0 and GCC-5.1.0 (Linux). There's not much to choose between
|
|
the various methods, but generally loop-unrolled methods perform better. Interestingly,
|
|
ordering the code to try and "second guess" possible optimizations
|
|
seems not to be such a good idea (method 3 below).
