BPAS Logo
The Basic Polynomial Algebra Subprograms (BPAS) library provides support for arithmetic operations with polynomials on modern computer architectures, in particular hardware accelerators. Typical operations are polynomial multiplication, multi-point evaluation and interpolation, real root isolation for both univariate and multivariate systems. Its code is written in C++ with CilkPlus extension targeting multi-core processors.

Polymorphic integration code features exact integration (as a formal sum) and symbolic-numeric integration of both dense and sparse representations of rational functions.
