The POEMS project is creating an environment for end-to-end performance modeling of complex parallel and distributed systems, spanning the domains of application software, runti...
We present predictive performance models of two of the petascale applications, S3D and GTC, from the DOE Office of Science workload. We outline the development of these models and...
Abstract--The lag of parallel programming models and languages behind the advance of heterogeneous many-core processors has left a gap between the computational capability of moder...
Performance models provide significant insight into the performance relationships between an application and the system used for execution. The major obstacle to developing perfor...
