Solving large scale linear equations is necessary in the areas of computer aided geometric modeling, computer aided decision, computer numerical computing and so on. Such linear equation solving is a hugely time-consuming process. According to the computer, the latest developments in multi-core CPU technology, a parallel aecelerating method of solving large-scale linear equations hased on the traditional LU decompression algorithm of solving linear equations was presented. The experiments indicate that the method is able to improve the speed of solving large scale linear equations exeellently.
