HYDRA-MPI: An Adaptive Particle-Particle, Particle-Mesh code for conducting Cosmological Simulations on MPP Architectures

We discuss the design and implementation of a parallel adaptive PM code, for massively parallel architectures. The code, although primarily designed for conducting gravitational simulations in a cosmological context, also includes a Smoothed Particle Hydrodynamics solver. The code is written in a combination of C, FORTRAN 77 and FORTRAN 90. The MPI-2 remote memory access standard is used for on...

Development of a Self-consistent Particle-in-cell (pic) Code Using a Time-adaptive Mesh Technique∗

For a large class of problems the self-consistent simulation of charged particle beams in linear accelerators is necessary. Typically, Particle-In-Cell (PIC) simulations use a fixed computational grid which has to resolve the bunch adequately. This leads to enormous memory consumption. Therefore, and especially in the 3D case, only rather short sections can be simulated. A remedy to this limita...

Adaptive Space-charge Meshing in the General Particle Tracer Code

Efficient and accurate space-charge calculations are essential for the design of high-brightness charged particle sources. Space-charge calculations in the General Particle Tracer (GPT) code make use of an efficient multigrid Poisson solver developed for non-equidistant meshes at Rostock University. GPT uses aggressive mesh-adaptation with highly non-equidistant spacing to speed up calculation ...

A Parallel Particle-In-Cell Code For Heterogeneous Hardware

An evaluation for a parallel Particle-In-Cell code leveraging heterogeneous hardware is presented. Two parallelization strategies are investigated on Intel R © Xeon Phi TM coprocessors. Hybrid parallelization is implemented to support optional workload offloading to coprocessors. A performance model is applied to load balance heterogeneous setups. Performance measurements of a benchmark show th...
