Statistics functions parameterised over the concrete representation of reals.
Utility functions for arrays.
Simple functional combinators.
Basic mathematical modules and functions.
The default prelude that is implicitly available in all Futhark files.
Various Second-Order Array Combinators that are operationally parallel in a way that can be exploited by the compiler.
Transforming arrays of tuples into tuples of arrays and back again. These are generally very cheap operations, as the internal compiler representation is always tuples of arrays.
Irregular segmented operations, like scans and reductions.
A non-comparison-based sort that sorts an array in O(k n) work and O(k log(n)) span, where k is the number of bits in each element.
