Paper Abstract:
|
The paper 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 EURORA system are reported. The work is done in the frame of the PRACE and SuperCA++ project. |
