Title: Code Optimization and Scaling of the Astrophysics Software Gadget on Intel Xeon Phi
Keywords: Gadget Software, Galaxy Data Set, Hybrid MPI/OpenMP Parallelization, High-Performance Computing, Scalability Tests, Intel Xeon Phi

Abstract: The whitepaper reports our investigation into the porting, optimization and subsequent performance of the astrophysics software package GADGET, on the Intel Xeon Phi. The GADGET code is intended for cosmological N-body/SPH simulations to solve a wide range of astrophysical tasks. The test cases within the project were simulations of galaxy systems. A performance analysis of the code was carried out and porting, tuning and scaling of the GADGET code were completed. As a result, the hybrid MPI/OpenMP parallelization of the code has been enabled and scalability tests on the Intel Xeon Phi processors, on the PRACE EURORA system are reported.
