| Abstract | The conceptual lattice design study of a new diffraction-limited light source has become much more computer intensive than that for the 3rd-generation rings. We are in a process of upgrading our existing accelerator modeling and simulation libraries, Goemon* in C++ and a new version Tracy#**, to fulfil such new demand. The C++ version has been actively used on the ALS HPC cluster for multi-objective optimization (MOGA) to optimize the ALS lattice***, and recently for ALS-U****. This time, based on the current version in C#, we extracted its subset and ported it to C and C++. The routines are made thread-safe to enable OpenMP locally, and CPU-time profiling was extensively used to remove redundancies. The new refitting method of quad settings brought smooth switching from 5-dim to 6-dim. The data structure itself is simplified for the use on GPU that is based on our previous effort of tracking particles in GPU*****. Tracy# itself is also upgraded to cooperate with these C/C++ versions. Their use from Python will be also mentioned. | |||||
