Computing activities - Py. ORBIT: - Statically linked executable - Stand-alone version E. G. on Laptops - Test close to integer - MAD-X: - Optics includes SC - 4 versions: Frozen, Adaptive, 3 D SC periodic, 3 D SC free - 3 D SC Kick and Sigma. Matrix done in development version ➔ Testing almost finished - OPENMP code instrumented by Harry Renshall well tested ➔ Gain 1. 8 significant for long-term studies. - Older versions (Frozen and Adaptive Mode) reviewed. - OPENMP reviewed by Harry (large STACKSIZE) - Several features still in review by Harry. (checkpoint restart, lost particles) 12. 03. 2017 SC WG - Frank 3

Computing activities - MAD-X Development - Inclusion into main MAD-X branch with Andrea ➔ independent module - 3 D SC kick included after all debugging done - Important key improvements: SC kick inclusion internal to MAD-X and also the matching phase ➔ Fully internal to MAD-X - Further developments with Yuri: numerical issues; coupling; extreme SC TS ~ 1; Regime without stable TWISS, SC Map for PTC; non-Gaussian distributions - Tools: - Six. Track with SC ➔ Frozen very fast in coll Riccardo - Sodd - MAP and Normal. Form Tool using PTC ➔ replacement of Etienne’s old version - Normal. Form in MAD-X/PTC with SC - Stand-alone PTC model E. G.
