chrysoliteazalea / conjugategradients__distributed Goto Github PK

This is a parallel conjugate gradients program for distributed memory systems. It can be compiled with any C++ compiler that supports OpenMP and Message Passing Interface, for example:

• mpic++ ConjugateGradients.cpp -o ConjugateGradients

The only accepted command line argument is the task file name (can be generated with task generator). The task file has the following format:

• The first line contains the number of the equations.
• All the other lines excepth the last two contain the coefficients of the system. The coefficient matrix of the system should be positively defined and symmetric!
• The next line contains the initial approximation
• The last line contains the acceptable error.
