摘要

The summary of this report is: (1) The range of scales (Lambda) of a system is not a Lorentz invariant and can vary greatly for some systems. (2) There exists an optimum frame which minimizes (Lambda). (3) We demonstrated speedup of x1000 for PIC simulation of relativistic beam interacting with electron background. (4) It is not in contradiction with the conventional scientific wisdom that 'complexity' is an invariant. (5) We identified three domains of application (laser-plasma acceleration, e-cloud in HEP accelerators, free electron lasers) for which speedup ranging from 2 to 4 orders of magnitude were demonstrated on toy problems.
