SLA-based job submission and scheduling with the Globus Toolkit 4
(Wydawnictwa AGH, 2012) Tenschert, Axel; Kübert, Roland
High performance computing is nowadays mostly performed in a best effort fashion. This is surprising as the closely related topic of grid computing, which deals with the federation of resources from multiple domains in order to support large jobs, and cloud computing, which promises seemingly infinite amounts of compute and storage, both offer quality of service (QoS), albeit in different ways. Long-term service level agreements (SLAs), which require the establishment of SLAs long in advance of their actual usage, seem a promising way for the offering of QoS guarantees in an HPC environment in a way that is not disruptive to the business models employed today. This work uses the long-term SLA approach as a basis for the provisioning of service levels for HPC resources and presents an SLA management framework to support this. Flexibility is provided by providing SLAs with different service levels, support for which is integrated into job submission and scheduling. The SLA management framework can, on a high level, be used in a generic fashion and an implementation is presented that is evaluated against a motivating scenario.

The application of a noise mapping tool deployed in grid infrastructure for creating noise maps of urban areas
(Wydawnictwa AGH, 2013) Szczodrak, Maciej; Kotus, Józef; Czyżewski, Andrzej; Kostek, Bożena
The concept and implementation of the system for creating dynamic noise maps in PL-Grid infrastructure are presented. The methodology of dynamic acoustical map screating is introduced. The concept of noise mapping, based on noise source and propagation models, was developed and employed in the system. The details of incorporation of the system to the PL-Grid infrastructure are presented. The results of simulations performed by the system prototype are depicted. The results in the form of noise maps obtained by a system are compared with some other solutions in order to investigate accuracy.

Towards a grid infrastructure for hydro-meteorological research
(Wydawnictwa AGH, 2011) Schiffers, Michael; Kranzlmüller, Dieter; Clematis, Andrea; D'Agostino, Daniele; Galizia, Antonella; Quarati, Alfonso; Parodi, Antonio; Morando, Marina; Rebora, Nicola; Trasforini, Eva; Molini, Luca; Siccardi, Franko; Craig, George C.; Tafferner, Arnold
The Distributed Research Infrastructure for Hydro-Meteorological Study (DRIHMS) is a co-ordinated action co-funded by the European Commission. DRIHMS analyzes the main issues that arise when designing and setting up a pan-European Grid-based e-Infrastructure for research activities in the hydrologic and meteorological fields. The main outcome of the project is represented first by a set of Grid usage patterns to support innovative hydro-meteorological research activities, and second by the implications that such patterns define for a dedicated Grid infrastructure and the respective Grid architecture.

WebALLTED: interdisciplinary modeling in grid and cloud
(Wydawnictwa AGH, 2013) Zgurovs'kij, Mihajlo Zaharovič; Petrenko, Anatolij Ivanovič; Ladogubec', Volodimir Vasil'ovič; Fìnogenov, Oleksij Dmitrovič; Bulah, Bogdan Vìktorovìč
This paper presents a multi-layered architecture of computer simulation software capable of utilizing grid and cloud resources, characterized in that the functionality of the system is distributed according to a service-oriented approach, and the system supports the execution of custom user-defined computing scenarios in grid or in cloud (by web services orchestration with an adherence to existing standards) but hides the complexity of direct web services management from the user with the help of the abstract workflow model and a web-accessible problem solving environment with a graphical workflow editor.
