Coherent synchrotron radiation (CSR) is an effect of self-interaction of an electron bunch as it traverses a curved path. It can cause a significant emittance degradation and microbunching. We present a new high-performance 2D, particle-in-cell code which uses massively parallel multicore GPU/GPU platforms to alleviate computational bottlenecks. The code formulates the CSR problem from first principles by using the retarded scalar and vector potentials to compute the self-interaction fields. The speedup due to the parallel implementation on GPU/CPU platforms exceeds three orders of magnitude, thereby bringing a previously intractable problem within reach. The accuracy of the code is verified against analytic 1D solutions (rigid bunch).

Efficient implementation of general-purpose particle tracking on GPUs can bring significant performance benefits to large-scale tracking simulations and direct (tracking-based) accelerator optimization techniques. This presentation is an update on the current status of our work on accelerating Argonne National Lab’s particle accelerator simulation code ELEGANT [*] using CUDA-enabled GPU. We summarize the performance of beamline elements ported to GPU, and discuss optimization techniques for some important collective effects kernels. We also outline briefly our testing and code validation infrastructure within ELEGANT and present the latest results of scaling studies with realistic lattices of the GPU-accelerated version of the code.

This talk will review current online modeling tools used for proton linacs and then focus on a new approach that marries multi-particle beam dynamics with modern GPU technology to provide pseudo real-time beam information in a control room setting. Benefits to be discussed will include fast turnaround, accurate beam quality prediction, cost efficiency, test bed for new control and operation scheme development and operator training.
