CoCoPeLia: Communication-Computation Overlap Prediction for Efficient Linear Algebra on GPUs

Graphics Processing Units (GPUs) are well established in HPC systems and frequently used to accelerate linear algebra routines. Since data transfers pose a severe bottleneck for GPU offloading, modern GPUs provide the ability to overlap communication with computation by splitting the problem to fine-grained sub-kernels that are executed in a pipelined manner. This optimization is currently underut...
