MPI stands for the Message Passing Interface. Written by the MPI Forum (a large committee comprising of a cross-section between industry and research representatives), MPI is a standardized API typically used for parallel and/or distributed computing. The MPI standard is comprised of 2 documents: MPI-1 (published in 1994) and MPI-2 (published in 1996). MPI-2 is, for the most part, additions and extensions to the original MPI-1 specification. The MPI-1 and MPI-2 documents can be downloaded from the official MPI Forum web site: http://www.mpi-forum.org/. Open MPI is an open source, freely available implementation of both the MPI-1 and MPI-2 documents. The Open MPI software achieves high performance the Open MPI project is quite receptive to community input.

anb 版的LBM程序 This code was written to show beginners in a simple and c short way the relevant procedures of a lattice Boltzmann solver, c pointing on how everything works "in principle". Nearly all c procedures could be implemented other (and better) as it is done c here, and even the algorithms used here could be changed to c save memory and increase performance. But the code works correct, c and we hope it will be good starting point for the first steps c in the lattice Boltzmann field. Good luck !

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.

In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.

Introduction Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.
