Main libraries

lib/github.com/diku-dk/linalg/linalg

Small library of simple linear algebra-ish operations.

lib/github.com/diku-dk/linalg/lu

LU-decomposition.

lib/github.com/diku-dk/linalg/lu_tests
lib/github.com/diku-dk/linalg/nmf

Non-negative matrix factorisation.

lib/github.com/diku-dk/linalg/nmf_tests
lib/github.com/diku-dk/linalg/qr

Implementations of QR decomposition. At the moment, these are not very fast for single large matrices, but they are serviceable. Performance is quite good on "batches" on many smaller matrices (i.e. when you map QR decomposition), where "small" is less than 16x16 or 32x16.

Supporting libraries

/prelude/ad

Definitions related to automatic differentiation.

/prelude/array

Utility functions for arrays.

/prelude/functional

Simple functional combinators.

/prelude/math

Basic mathematical modules and functions.

/prelude/prelude

The default prelude that is implicitly available in all Futhark files.

/prelude/soacs

Various Second-Order Array Combinators that are operationally parallel in a way that can be exploited by the compiler.

/prelude/zip

Transforming arrays of tuples into tuples of arrays and back again.

lib/github.com/diku-dk/cpprandom/random

Random number generation inspired by <random> in C++.
