Introduction:
This package is for basic algebra computation on GPU. And it was developed from the end of 2003 when I was in the Institute of Software, Chinese Academy of Sciences. After I implmented some basic functions, I stopped going further and transfer to implement the fluid simulation on GPU.

Features:
1. Vector + / - Vector 
2. Matrix * Vector(including sparse matrix and dense matrix) 
3. Matrix * Matrix 
4. Reduction(Vector->Scalar) 
5. Jacobi Iteration Method 
6. Conjugate Gradient Method 

But here I have to mention that there still exist problems for the reduction inner product operation, so it will cause problem to the conjugate gradient method implmentation.

Directory structure:
----PDESimulatorOnGPU
--------Version6.0
--------FragmentProgram(just backup of fragment programs)
--------ConsoleGPU(once try to use a console application to test those algorithms, but not go on)
--------Available fragment programs

Actually, the whole stucutre is in a mess but I try to make the name of those files and functions more recognizable. Hope you can find what you want.  


You can drop me an email if you have any comment, THANK YOU. 
But maybe I have no time to improve it anymore and if you improve it and let me know, I will appreciate.
