The Cuba library offers a choice of four independent routines for multidimensional numerical integration: Vegas, Suave, Divonne, and Cuhre. They work by very different methods, first three are Monte Carlo based. All four have a C/C++, Fortran interface and can integrate vector integrands. Their invocation is very similar, so it is easy to substitute one method by another for cross-checking. For further safeguarding, the output is supplemented by a chi-square probability which quantifies the reliability of the error estimate.

24 Nov 11: - Significantly rearranged Divonne, e.g. unrolled the recursion on regions, for better parallelizability. - Improved parallelization through DoSample. - Automatic detection and usage of the free cores on a machine, or else set CUBACORES to the number of cores one wishes to utilize, with negative numbers meaning "up to" depending on availability (e.g. -2 means "use up to two f more»
