A2D HTC (Agros2D High Throughput Computing) is a system for distributed computation of serious tasks used in Agros2D application. Main part of the system is Python htcondor module, which extends existing possibilities of the variant module (part of the OptiLab application) and allows the use of remote clusters operated by HTCondor. System is used for efficient solution of parametric studies, sensitivity analyses and optimization tasks. Parallelization of models, connection with HTCondor and control of the process is fully automated and heuristics for efficient operations is included.
