The development of integrated applied software environment for mathematical modelling, which is oriented onto solving interdiscipline direct and inverse problems by the wide circle ofusers in the framework of cloud computing at the supercomputers of petaflops level stands the bigset of issues of methodical, technological and organizational types. In this paper, we consider the conception of basic system of modelling (BSM), whose functionality is supposed in the frameworkof collective using computing center (CUCC). BSM presents the integrated software environmentwhich supports all main technological stages of large scale computational experiments, adaptedto evolution of the problem models and algorithms, as well as to architectures of multi-processorcomputational systems (MCS), and intended to the long life circle, which is provided by the efficientconstructing of applied program packages (APPs). The achivement of the total high performanceof CUCC is considered as the constrained optimization problem for the schedule of computationaltasks, under taking into account the necessary resourses for the particular applications.
Keywords: scalable parallelism, cloud computing, mathematical modelling, multiprocessor computational system, basic system of modelling, applied software.
