Title:
Design, Implementation and Test of Efficient GPU to GPU Communication Methods 
Translated title:
Entwurf, Entwicklung und Test von Effizienten Kommunikationsmethoden zwischen GPUs 
Abstract:
Stencil codes are commonly used to solve many problems. On parallel heterogeneous systems with CPUs and GPUs, the domain is usually split and assigned to GPUs, where it is further divided to GPU blocks. The iterative distributed stencil computation consists of two steps – computation and communication, where the subdomains exchange boundary data, also called ’halo exchange’. On multi-node systems, it is crucial to efficiently transfer data from one GPU to another via MPI, as a de-facto sta...    »
