Abstract :
A study of the fundamental obstacles to accelerate the preconditioned conjugate gradient method on modern graphic processing units (GPUs) is presented and several techniques are proposed to enhance its performance over previous work. The performance increase observed when implementing one of our proposed enhancements over traditional approaches is reported.
