• Eigen

How to build

$ git clone https://github.com/gishi523/cusparse-cholesky-solver.git
$ cd cusparse-cholesky-solver
$ mkdir build
$ cd build
$ cmake ../
$ make

How to run

simple_cholesky sample

./samples/simple_cholesky/sample_simple_cholesky

large_cholesky sample

./samples/large_cholesky/sample_large_cholesky matrix-market-file

• For example, download the ND/ND6k matrix from the SuiteSparse Matrix Collection
• Unpack the nd6k.mtx and pass to the program

./samples/large_cholesky/sample_large_cholesky nd6k.mtx
