Parallel Colt

Parallel Colt is a set of multithreaded version of Colt. It is a collection of open-source libraries for High Performance Scientific and Technical Computing written in Java. It contains all the original capabilities of Colt and adds several new ones, with a focus on multi-threaded algorithms.

Capabilities
Parallel Colt has all the capabilities of the original Colt library, with the following additions.


 * Multithreading
 * Specialized Matrix data structures
 * JPlasma
 * Java port of PLASMA (Parallel Linear Algebra for Scalable Multi-core Architectures).
 * CSparseJ
 * CSparseJ is a Java port of CSparse (a Concise Sparse matrix package).
 * Netlib-java
 * Netlib is a collection of mission-critical software components for linear algebra systems (i.e. working with vectors or matrices).
 * Solvers and preconditioners
 * Mostly adapted from Matrix Toolkit Java
 * Nonlinear Optimization
 * Java translations of the 1-dimensional minimization routine from the MINPACK
 * Matrix reader/writer
 * All classes that use floating-point arithmetic are implemented in single and double precision.
 * Parallel quicksort algorithm
