LightMat C++ Matrix class library  
LightMat is a portable C++ class library for efficient arithmetic operations and basic mathematical functions on vectors, matrices, 3- and 4-dimensional arrays. The library is specially optimized for vectors and matrices with dimensions 3 and 4 (i.e. 3x3 and 4x4). The library is optimized to minimize or eliminate object creation overhead which are especially important for small objects. Loops are unrolled whenever possible to provide better performance. Data is stored on the stack when possible i.e. small objects, otherwise on the heap. Arrays can be converted to strings and printed out.

A Template Numerical Toolkit for Linear Algebra  
The Template Numerical Toolkit is a collection of mathematical libraries for numeric computation in C++. Its fundamental classes include vectors, matrices, and multidimensional arrays. The basic goal is to allow one to express mathematical computation at a higher level of abstraction, while still retaining some control over performance and optimization issues. Doing so requires a careful analysis to balance these tradeoffs. The toolkit provides an integrated collection of generic matrix/vector classes based on components of the Standard Template Library (STL) and ANSI C++, together with specialization of generic algorithms for maximal efficiency.

[FREESW]Blitz++  
The C++ programming language offers many features useful for tackling complex scientific computing problems: inheritance, polymorphism, generic programming, and operator overloading are some of the most important. Unfortunately, these advanced features came with a hefty performance pricetag: until recently, C++ lagged behind Fortran's performance by anywhere from 20% to a factor of ten. As a result, the adoption of C++ for scientific computing has been slow. Is there a way to soup up C++ so that we can keep the advanced language features but ditch the poor performance? This is the goal of the Blitz++ project: to develop techniques which will enable C++ to rival - and in some cases even exceed -- the speed of Fortran for numerical computing, while preserving an object-oriented interface. The Blitz++ Numerical Library is being constructed as a testbed for these techniques.

LHC++  
The LHC++ project aims to replace the current CERNLIB software libraries with a suite of OO software with roughly equivalent functionality. The scope of the project covers: foundation level class libraries, mathematical libraries, graphical libraries, visualization toolkits, data analysis, histograms, event generators (in collaboration with, e.g., Lund), detector simulation (GEANT4 via RD44 at present), object persistency (Objectivity/DB via RD45 at present). The primary focus is on C++ solutions, although recent developments in software, such as Java-based applications, are also closely monitored. The strategy of LHC++ is to identify the HEP needs in these areas and to provide solutions broadly applicable to experiments.

Several others have contributed ideas and code. While it has been ported to other platforms, libg++ is normally used on Unix systems in conjunction with the GNU C++ (g++) compiler. It is available via anonymous ftp from prep.ai.mit.edu, among other sources.

Integer multiplication benchmarks  
apfloat, BN, CLN, FreeLIP, giantint, GNU MP,... These are some timings for multiplication of two b-bit integers, for various values of b, using various libraries. Most of the timings reported here are for a Pentium II-400, running Linux 2.2. I used gcc 2.7.2.3 for C libraries and egcs 2.90.29 for C++ libraries. Note that the choice of compiler and compiler options can make a big difference in speed. A few timings are for a Pentium-133, running Linux 2.0, using egcs 2.90.21 for C libraries.

The MorphCGI C++ class library encapsulates the set of common functionality that is used to manipulate CGI (Common Gateway Interface) data. It consists of an easy to use API and intuitive accessors to obtain and handle CGI data.
