Magnetohydrodynamic (MHD)\nsimulations are now widely used for numerical modeling of global and macroscopic phenomena. In\nthe framework of the MHD approximation, however, diffusion coefficients such as resistivity and\nadiabatic index are given from empirical models. Thus there are recent attempts to understand\nfirst-principle kinetic processes in macroscopic phenomena, such as magnetic reconnection and the\nKelvin\u2013Helmholtz (KH) instability via full kinetic particle-in-cell and Vlasov codes. In the present\nstudy, a benchmark test for a new four-dimensional full electromagnetic Vlasov code is performed.\nFirst, the computational speed of the Vlasov code is measured and a linear performance scaling is\nobtained on a massively parallel supercomputer with more than 12 000 cores. Second, a\nfirst-principle Vlasov simulation of the KH instability is performed in order to evaluate current\nstatus of numerical techniques for Vlasov simulations. The KH instability is usually adopted as a\nbenchmark test problem for guiding-center Vlasov codes, in which a cyclotron motion of charged\nparticles is neglected. There is not any full electromagnetic Vlasov simulation of the KH instability;\nthis is because it is difficult to follow E X B drift motion accurately without approximations. The\npresent first-principle Vlasov simulation has successfully represented the formation of KH vortices\nand its secondary instability. These results suggest that Vlasov code simulations would be a\npowerful approach for studies of cross-scale coupling on future Peta-scale supercomputers.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/14151"}, {"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://dx.doi.org/10.1063/1.3422547"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Institute of Physics"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright (2010) American Institute of Physics.
