Abstract

The neoclassical transport is a lower limit of the whole proposed solutions such as self-scheduling algorithms, pilot transport in plasmas confined in fusion devices, either job techniques have demonstrated a great variety of stellarators or tokamaks. Even more, the determination of a vast database compiling monoenergetic and transport coefficients is very useful for coupling different codes, which can use those values as input data. The DKEsG application is able to obtain such parameters on Grid infrastructures. Since a large number of regular jobs are needed for filling the aforementioned database, a fast and robust execution scheme is necessary. For this purpose, a new DRMAA-enabled DKEsG version that makes use of a new generic pilot-job platform is used, avoiding the most significant overheads related to standard Grid middleware. This new developed mechanism is suitable for many other scientific applications involving high-throughput calculations
