Parallel Algorithm for Calculating the Radius of Stability in Multicriteria Optimization Conditions el. The criteria of the process optimality are considered, such as minimization of the aromatic hydrocarbons content in the final reformate in accordance with environmental requirements and; maximizing the octane number of the reformate. The problem of analyzing the stability of the Pareto set is fo

Parallel Global Search Algorithm for Optimization of the Kinetic Parameters of Chemical Reactionsodern chemical industry to produce synthesis gas. As a chemical reaction, the process of pre-reforming propane on a Ni catalyst is assumed. To simulate a chemical process, it is necessary to develop a kinetic model of the process, that is, to determine the kinetic parameters. To do this, the inverse

Parameters Optimization of Linear and Nonlinear Solvers in GeRa Code linear solvers as the most time-consuming stage of the solution. Eleven different solvers are considered and their properties are discussed in solving both model and real-life problems with complex geological structures. The optimization of the relaxation parameter to accelerate the convergence of

Implementation of?Elliptic Solvers Within ParCS Parallel Frameworkment of the new non-hydrostatic global atmospheric model at INM RAS and Hydrometcentre of Russia. The efficiency and parallel scalability of the implemented algorithms have been tested for the elliptic problem typical for numerical weather prediction models using semi-implicit discretization at the cubed sphere grid.
