Generic data-assimilation toolbox written in java, with native (c and fortran) libraries for high performance computing. Provides tools to couple to your own model and a wide range of algorithms, ranging from parameter calibration to Kalman filters.

Geometric Regression Library (GeoRegression) is an open source Java geometry library for scientific computing with a focus on 2D/3D space. GeoRegression provides the ability to estimate the closest point/distance between geometric primitives, best-fit shapes, and best fit geometric transform between sets of objects. It is designed for high performance and ease of use. GeoRegression has been release under an LGPL license for both commercial and non-commercial use.

Math Expression Parser 4 Java MEP4J is a high performance math expression strings parser for Java (J2SE >= 5). Compare its performance against similiar libraries and let me know your experince. The library manages the 5 operators (+, -, /, %, *) together with the following functions: - "abs" - "cos" - "sin" - "acos" - "asin" - "cosh" - "sinh" - "tan", - "tanh" - "atan" - "sqrt" - "cbrt" - "root" - "log" - "log10" - "log1p" - "exp" - "expm1" - "atan2" - "pow" The library supports variables (case insensitive), custom and pre-loaded ("e" and "pi"). ...

...Concerning performance, the tool enables to check all examples in the PVS Bernstein testsuite within a second, which can be an order of magnitude faster than some other tools such as QEPCAD or REDLOG. Although JBernstein uses double, it offers automatic error-estimation capabilities (experimental) so that the generated result is correct (the solver may return unknown when the error-estimate is too large)

...Mutable complex numbers can then be used in the most performance-critical parts of the code with immutable complex numbers being used elsewhere. Performance improvement of mutable complex numbers is 10x in the best-case scenario and about 2x in real life complex number code. The package is released under the liberal MIT license.

Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity...

Java Micro Benchmark - control tasks required to determine the comparative performance characteristics of the computer system on different platforms. Can be used to determine the effect of different software on the performance of a computer system.

JTransforms is the first, open source, multithreaded FFT library written in pure Java. Benchmark results show better performance than FFTW. The latest version is available at http://github.com/wendykierp/JTransforms.

Geom4J is a computational geometry library for Java. It contains implementation of the most important computational geometry data structures and algorithms coded in pure Java, designed for ease of use and optimized for performance.

Parallel Colt is a multithreaded version of Colt - a library for high performance scientific computing in Java. It contains efficient algorithms for data analysis, linear algebra, multi-dimensional arrays, Fourier transforms, statistics and histogramming

jmathtools, mathematical / scientific java stuff designed to be easily used and modified, not really designed for high performance calculation.

Distributed Java Fractal Generator. DJFractals can computes fractals in arbitrary precision using any CPU available from high performance multi-processors clusters of computers to grid of JavaCards and even at the same time.

Our goal is to surpass the performance of the Matching Pursuit and Best Basis algorithms and provide progressive time-frequency analysis.
