Abstract:
Methods of numerical simulation of two-dimensional short laser pulse nonlinear dynamics are discussed. In this work parallel processing methods for modern CPU (central processing units) architectures supporting non-uniform memory access are considered. The method of adaptive mesh subdivision is proposed to reduce non-uniform load of each CPU during processing of nonlinearity. The results of the tests performed on the Intel Nehalem based a workstation with eight cores are presented.

Keywords:
computational electromagnetic methods (050.1755); ionization (260.3230); ultrafast phenomena (260.7120); optical breakdown; parallel processing; non-uniform memory access (NUMA); adaptive calculations.
