The KAP preprocessor optimizes DEC Fortran and DEC C programs to achieve their best performance on Digital Alpha systems. One key optimization that KAP performs is the parallelization of programs for Alpha shared memory multiprocessors that use the new capabilities of the DEC OSF/1 version 3.0 operating system with DECthreads. The heart of the optimizer is a sophisticated decision process that ...

MT2DInvMatlab is an open-source MATLAB software package for two-dimensional (2D) inversion of magnetotelluric (MT) data; it is written in mixed languages of MATLAB and FORTRAN. MT2DInvMatlab uses the finite element method (FEM) to compute 2D MTmodel responses, and smoothness-constrained least-squares inversion with a spatially variable regularization parameter algorithm to stabilize the inversi...

A new program control structure is proposed in this paper which is suitable for expressing a variable number of nested loops. This control structure is useful in combinatorial problems and in problems requiring backtracking. Implementation details are discussed and some illustrative examples are given which employ this new program control structure. The incorporation of this control structure i...
