Echelon is a new software product for large scale high performance reservoir simulation. It was developed from inception for fine-grained parallelism targeting GPUs. It is exceptionally fast, typically achieving between 10x to 50x faster runtimes than leading commercial simulators and has demonstrated scaling to very large systems with 100's of millions of flow-sim cells, in some cases without upscaling.
