Newmat, a C++ matrix library, is intended for scientists and engineers who need to manipulate a variety of types of matrices using standard matrix operations. The library includes the operations *, +, -, concatenation, inverse, transpose, conversion between types, submatrix, determinant, Cholesky decomposition, QR triangularisation, singular value decomposition, eigenvalues of a symmetric matrix, sorting, fast Fourier and trig. transforms, printing, and an interface with Numerical Recipes in C.
OOMPI is an object-oriented interface to the MPI message passing library standard. It is used at a much higher level than the standard MPI C++ bindings, providing a full class library that takes advantage of many C++/object oriented abstractions for message passing. It is a thin layer that runs over any MPI-1.1 compliant C implementation.
rt is an n-dimensional raytracer. It supports any positive number of spatial dimensions, color and grayscale, cylinders with an arbitrary number of round dimensions (spheres and cubes are special cases of cylinders), quadratic surfaces, convex hulls, regular polytopes, unions, intersections, cuts, extrusions, reflection, refraction, functional texture maps, portals into other traces, ambient light, multiple light sources, directional light sources, gamma correction, fish-eye effect, and output as PNG or PPM. It has been tested under DOS, Solaris, Digital Unix, FreeBSD, NetBSD, Linux, Ultrix, System V, and BeOS.
The Simple Sockets Library makes sockets easy to use and comes as public domain source code. It resembles C's file I/O, uses whatever port is available, has named servers and port reuse, streaming/blocking sockets used, polling support, blocking/selection support via numerous functions, timeout control and firewall support.
Simple Atmel and PIC programmer is a program which downloads code into the Atmel and PIC microprocessor chips. To use it you will need a programmer board attached to your parallel or serial port. This release programs FSTRT and SPIEN fuse bits in the AT90S8515 processor to enable serial programming. Hardware schematics are included for using external power and the parallel port.
PDBCat can be used to manipulate and process PDB files using commonly available text-processing tools such as Perl, awk, etc. The Brookhaven Protein Data Bank stores atomic coordinate information for protein structures in a column-based format which is designed to be read easily read by FORTRAN programs. PDBCat converts the ATOM and HETATM records of PDB files from this column-based format to a field-based one that is more easily processed by standard Unix tools.
This is a stable version of the Interoperable Message Passing Interface (IMPI) Server. It fully conforms to the January 2000 IMPI Draft Standard. IMPI is used to join multiple MPI implementations into a single parallel job. This package is independent of any specific MPI or IMPI implementation, and is intended for end users as well as IMPI implementors.
