Title: Code Optimization and Performance Analysis of Oceanographic Software Package NEMO for GPGPU Systems
Keywords: High-Performance Computing, Graphical Processing Accelerators, Parallel Code Optimization, NEMO Ocean software, Parallel Performance Analysis

Abstract: The paper presents our experience in code optimization and performance analysis of software package NEMO on hybrid parallel computer systems with accelerators. NEMO Ocean is a software package for oceanology, simulating ocean gyres and sea-ice models. Code optimization and performance analysis are performed for the case study of NEMO ORCA2_LIM configuration. All experiments are conducted on a heterogeneous IBM Blade Center comprising Blade Servers and NVidia Tesla M2075 accelerators. The parallel software for oceanology NEMO has been optimized for GPGPU systems. For this purpose an optimization has been implemented and verified. The experimental results show that the optimized NEMO code provides considerably better performance than the original code.
