GRAPLEr is a distributed computing system that integrates and applies overlay virtual network, high-throughput computing, and Web service technologies. GRAPLEr allows submission of hundreds or thousands of General Lake Model (GLM) simulations, runs these lake model simulations efficiently, and retrieves model output. GRAPLEr image includes a new R package developed as part of the lake expedition.

Virtual Images of GRAPLEr are available from PRAGMA Boot Google Drive Virtual Cluster Image repository.
