Re: OPR-computation-related linear algebra problem
I just got a new computer at work with a Xeon E5-1620 and a Quadro 4000 GPU (256 CUDA cores). Using Matlab 2012b:
CPU Invert and Multiply: 1.4292s
CPU Linear Solver: 0.22521s
CPU Sparse Linear Solver: 0.034423s
GPU Invert and Multiply: 0.537926s
GPU Linear Solver: 0.218403s
Loading the N matrix into the GPU was 1.890602s.
Creating the Sparse Matrix for N was 0.032979s.
