Scalable Non-blocking Preconditioned Conjugate Gradient Methods

The preconditioned conjugate gradient method (PCG) is a popular method for solving linear systems at scale. PCG requires frequent blocking allreduce collective operations that can limit performance at scale. We investigate PCG variations designed to reduce communication costs by decreasing the numbe...
