ULTRA Evaluation

This work evaluates existing and emerging large-scale HEC architectures using a set of in-depth studies from full applications. The novel aspect of this research is the emphasis on full applica­tions, run with real input data and at the scale desired by application scientists in the domain. These problems are much more complicated than in traditional benchmarking suites such as the NAS Parallel Benchmarks or the LINPACK benchmark, and therefore reveal the kinds of performance issues that arise in applications that combine multiple physical models, perform large volumes of I/O, and for which the underlying kernels can be organized in various ways to match the features of a given architecture.
