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.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The whitepaper reports our investigation into the porting, optimization and subsequent performance of the astrophysics software package GADGET, on the Intel Xeon Phi.
