Multithreaded FLINT

FLINT provides a number of multithreaded functions, which use multiple threads by default if FLINT was built with at least pthreads. (This functionality works best when thread local storage is also available on the system.)

By default, FLINT will just use one thread. To control the maximum number of threads FLINT uses, one can call the function flint_set_num_threads(n), where \(n\) is the maximum number of threads to use.

One can also query the current thread limit by calling flint_get_num_threads().

Each version of FLINT brings new functions that are threaded by default.

Many core algorithms such as the FFT (for large integer and polynomial operations, including some factoring algorithms), integer factoring and multivariate polynomial algorithms are threaded in FLINT.

Please refer to \(code_conventions.txt\) for some preliminary guidance on how to write threaded functions in FLINT.
