Installation and testing the lofar software on ACC Cyfronet cluster Prometheus
(Wydawnictwa AGH, 2019) Kuligowska, Elżbieta; Czuchry, Maciej; Chyży, Krzysztof; Kundera, Tomasz; Roskowiński, Carole; Dziełak, Marta A.
We present the actual status and the most important issues related to the installation of the data reduction LOFAR software on high power computer Prometheus located in ACC Cyfronet. We refer to the software itself as well its practical use cases in the context of the scientific tool and the detailed installation/testing methodology. We address most typical challenges and problems that occurred during our attempts to set up the complete and ready-to-use LOFAR environment (including not only programs, but also libraries, scripts and other additional tools) on non-standard (cluster-type) computing system. The result of these works is then briey summarized. We also discuss the is- sues related to LOFAR documentation, maintenance, distribution and further development. Finally, we propose some future improvements.

Parallel and distributed calculations supported and managed by the relational database
(Wydawnictwa AGH, 2009) Oramus, Piotr
A simple, based on a relational database, system, for a management of a parallel and a distributed computer calculations, is presented. In the proposed system, the parallel calculations are carried out according to a master/slave model. Because an input and an output data of programs are stored directly in the database, the use of files is reduced to a minimum. The management system allows for a combination of computing power of many computers for solving a single numerical problem.
