We consider parameter identification of a hydride decomposition model by scanning the parameter space in parallel. Such problem is resource demanding, but suits best for Desktop Grid computing. Considering task retrieval as a game, we show that the search process can be improved to produce solutions faster in comparison with random search, with no or minor additional cost.

В работе рассматривается задача идентификации параметров модели разложения гидридов металлов методом параллельного сканирования пространства параметров. Задача является вычислительно емкой, но при этом хорошо подходит для выполнения в среде Desktop Grid. Выбор заданий рассматривается как математическая игра. В работе показано, что процесс поиска можно оптимизировать таким образом, чтобы получать решения быстрее по сравнению со случайным поиском, не требуя дополнительных накладных расходов.

Quantum structure or scattering calculations often belong to a class of computational problems involving the aggregation of a set of matrices representing a linear problem to be solved. The authors discuss a number of approaches based on cluster and grid computing, and discuss the implementations and the respective merits and shortcomings. The authors consider MPI-based cluster computing in a self-scheduling paradigm, CoBRA (a cpu-harvesting desktop grid) in a farmer-worker paradigm, and a batch-computing paradigm on BEGrid (the Belgian research grid facility). It is observed that for all paradigms an efficient implementation is possible, yielding results within a comparable time frame.
