Abstract

An approach is provided in which a system includes a GPU cluster. The GPU cluster includes multiple GPU nodes, that each includes a GPU core and a corresponding local cache. The GPU cluster also includes a shared memory and an internal bus that maintains cache coherency between the shared memory and the local caches included in the GPU nodes.
