tk500 is a multiplatform programming and cloning utility for the portable Yaesu VR-500 receiver. It can read the memory image from the radio, display the information graphically, and save it to a file. It can import information from an RT Systems .RDF file and export memory channel information to a .CSV (comma-separated values) file. Users are free to change most settings and write the memory image back to the receiver. tk500 exploits undocumented features within the radio.
Block Locally Optimal Preconditioned Eigenvalue Xolvers (BLOPEX) is a package, written in C and MATLAB, that includes an eigensolver implemented with the Locally Optimal Block Preconditioned Conjugate Gradient Method (LOBPCG). BLOPEX supports parallel MPI-based computations. BLOPEX is incorporated in the HYPRE package and is available as an external block to the PETSc package. Its main features are a matrix-free iterative method for computing several extreme eigenpairs of symmetric positive generalized eigenproblems; a user-defined symmetric positive preconditioner; robustness with respect to random initial approximations, variable preconditioners, and ill-conditioning (up to 10^16) of the stiffness matrix; and apparently optimal convergence speed.
SimGrid is a toolkit which provides core functionalities for the simulation of distributed applications in heterogeneous distributed environments. The specific goal of the project is to facilitate research in the area of parallel and distributed large scale systems such as Grids, P2P systems, and clouds. Its use cases encompass heuristic evaluation, application prototyping, or even real application development and tuning.
Openline is the open source version of Hotline. Hotline is a PC/MAC client/server application that provides users the ability to create and manage a desktop community. The application has file uploading and downloading, instant messaging, a bulletin board, threaded news, and public and private chat.
