DESCRIPTION:ABSTRACT: New laser facilities like ELI will provide intensities\, that are able to break the vacuum stability and produce new effects on ultra short length scales. No ordinary particle in cell (PIC) code can handle the necessary resolution\, not even on the most powerful super computers.  Nevertheless most of the simulation area does not show these effects\, therefore constant resolution on the grid is waste of compute power. We investigate how modern maxwell-solvers and particle-pushers\, including self forces\, can be implemented on an adaptive grid (AMR-PIC).  We combine these efforts with general acceleration methods\, like multi-threading/many-core implementations with Infiniband MPI\, micro vectorization and hardware acceleration like cell or GPGPU computing. The dynamic resolution changes\, require a sophisticated load balancing system. The work is in the evaluation process which data structures and algorithms are best to tackle the problem. We will focus on oru demo implementations and the concepts studied yet.
