Efficient submission of hybrid parallel tasks in grid

The method of efficient submission of hybrid tasks using both MPI and OpenMP technologies is considered. For flexible control of parameters of the parallel tasks submission to supercomputers (SC), the specification of the task description language was expanded. Support of the new attributes was implemented for all key components of the infrastructure. Interaction of the submission web service with a local resource manager is organized through special handlers for tasks of different types (single, openmp, mpi or hybrid). This provides transmission of the correct parameters for reservation of resources and task submission to the local SC-manager. The provided solution was tested on a grid testbed deployed on the basis of GridNNN middleware.
