Converting from COO to Compressed sparse matrix

Question

I wanted CSR files preferably from matrix market for my OpenCL library, I searched a lot for CSR generators in C but didn't get any. I find matrix market formats comfortable since they have defined the functions for read and write. I'm also curious how CUSP library in CUDA C is able to read COO matrix from an .mtx file and can convert it to CSR format. Thanks in advance

You can see the code for reading matrices in cusp::io.

Before you go reinventing the wheel, you might want to take a look at ViennaCL, which already include OpenCL CSR matrix types, an spMV implementation, and a number of iterative solvers built on that spMV implementation.

Thanks a lot, you're right about that. I deployed Vienna and going through the source code – Jayavanth Jul 11 '11 at 11:05
