Comparative Performance BerkeleyGW* Sigma Phase 1 NODE APPROVED FOR PUBLIC PRESENTATION NEW 1 BerkeleyGW* Sigma Phase Speed Up 1.58X 1.31X 1.28X 1 Application: BerkeleyGW* (Sigma) Description: BerkeleyGW is a massively parallel computational package for electron-excited state properties. Sigma is the second half of the GW code. It gives the quasiparticle selfenergies and dispersion relation for quasielectron and quasihole states. Availability: • Code: Available here (version 1.1 beta). • Recipe: None. The exact input used is not available to the public although a similar input is available. Usage Model: MPI+OMP. In symmetric mode, MPI ranks are distributed to both the host and KNC card. Each MPI rank uses OMP threads (Hybrid). 0 Intel® Xeon® processor E5-2697 v2 Intel® Xeon® processor E5-2697 v3 Xeon E5-2697 v2 + Intel® Xeon Phi coprocessor 7120A Xeon E5-2697 v3 + Intel® Xeon Phi coprocessor 7120A “Xeon E5-2697 v2/v3” = Intel® Xeon® processor E5-2697 v2/v3 Highlights: Hybrid MPI+OMP allows code to be run on both Intel® Xeon® processors and Intel® Xeon Phi coprocessors without any source modifications. Results: Intel® Xeon® processor E5-2697 v3 speed up is up to 1.31X, and Intel Xeon processor E5-2697 v3 + Intel® Xeon Phi coprocessor 7120A speed up is up to 1.58X over the baseline processor.

SOURCE: INTEL MEASURED RESULTS AS OF DECEMBER, 2014 Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products.
