How to Use Google App Engine for Free Computing
Found in: IEEE Internet Computing
By Maciej Malawski,Maciej Kuźniar,Piotr Wójcik,Marian Bubak
Issue Date:January 2013
pp. 50-59
Can the Google App Engine cloud service be used, free of charge, to execute parameter study problems? That question drove this research, which is founded on the App Engine's newly developed Task Queue API. The authors created a simple and extensible framew...
Energy-Constrained Provisioning for Scientific Workflow Ensembles
Found in: 2013 International Conference on Cloud and Green Computing (CGC)
By Ilia Pietri,Maciej Malawski,Gideon Juve,Ewa Deelman,Jarek Nabrzyski,Rizos Sakellariou
Issue Date:September 2013
pp. 34-41
Large computational problems may often be modelled using multiple scientific workflows with similar structure. These workflows can be grouped into ensembles, which may be executed on distributed platforms such as the Cloud. In this paper, we focus on the p...
Evaluation of Cloud Providers for VPH Applications
Found in: 2013 13th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (CCGrid)
By Marian Bubak,Marek Kasztelnik,Maciej Malawski,Jan Meizner,Piotr Nowakowski,Susheel Varma
Issue Date:May 2013
pp. 200-201
Infrastructure as a Service (IaaS) clouds are considered interesting sources of computing and storage resources for scientific applications. However, given the large number of cloud vendors and their diverse offerings, it is not trivial for research projec...
Cost- and deadline-constrained provisioning for scientific workflow ensembles in IaaS clouds
Found in: 2012 SC - International Conference for High Performance Computing, Networking, Storage and Analysis
By Maciej Malawski,Gideon Juve,Ewa Deelman,Jarek Nabrzyski
Issue Date:November 2012
pp. 1-11
Large-scale applications expressed as scientific workflows are often grouped into ensembles of inter-related workflows. In this paper, we address a new and important problem concerning the efficient management of such ensembles under budget and deadline co...
Providing security for MOCCA component environment
Found in: Parallel and Distributed Processing Symposium, International
By Michal Dyrda,Maciej Malawski,Marian Bubak,Syed Naqvi
Issue Date:May 2009
pp. 1-7
The subject of this paper is a detailed analysis and development of security in MOCCA, a CCA-compliant Grid component framework build over H2O, a Java-based distributed computing platform. The approach is to extend H2O with an authentication mechanism that...
Virtual Laboratory for Development and Execution of Biomedical Collaborative Applications
Found in: Computer-Based Medical Systems, IEEE Symposium on
By Marian Bubak, Tomasz Gubala, Maciej Malawski, Bartosz Balis, Wlodzimierz Funika, Tomasz Bartynski, Eryk Ciepiela, Daniel Harezlak, Marek Kasztelnik, Joanna Kocot, Dariusz Krol, Piotr Nowakowski, Michal Pelczar, Jakub Wach, Matthias Assel, Alfredo Tirado-Ra
Issue Date:June 2008
pp. 373-378
The ViroLab Virtual Laboratory is a collaborative platform for scientists representing multiple fields of expertise while working together on common scientific goals. This environment makes it possible to combine efforts of computer scientists, virology an...
Grid Support for HLA-Based Collaborative Environment for Vascular Reconstruction
Found in: e-Science and Grid Computing, International Conference on
By Katarzyna Rycerz, Marian Bubak, Maciej Malawski, Peter Sloot
Issue Date:December 2006
pp. 48
Collaborative environments where users can interact with running simulations are an important aspect of e- Science. To achieve efficient execution of High Level Architecture (HLA)-based collaborative environments on the Grid, we introduce a Grid HLA Manage...
Semantic Composition of Scientific Workflows Based on the Petri Nets Formalism
Found in: e-Science and Grid Computing, International Conference on
By Tomasz Gubala, Daniel Herezlak, Marian Bubak, Maciej Malawski
Issue Date:December 2006
pp. 12
The idea of an application described through its workflow is becoming popular in the Grid community as a natural method of functional decomposition of an application. It shows all the important dependencies as a set of connections of data flow and/or contr...
MOCCA - Towards a Distributed CCA Framework for Metacomputing
Found in: Parallel and Distributed Processing Symposium, International
By Maciej Malawski, Dawid Kurzyniec, Vaidy Sunderam
Issue Date:April 2005
pp. 174a
We describe the design and implementation of MOCCA, a distributed CCA framework implemented using the H2O metacomputing system. Motivated by the quest for appropriate metasystem programming models for large scale scientific applications, MOCCA combines the...
Towards a Grid Management System for HLA-Based Interactive Simulations
Found in: Distributed Simulation and Real Time Applications, IEEE/ACM International Symposium on
By Katarzyna ZajÄ…c, Marian Bubak, Maciej Malawski, Peter Sloot
Issue Date:October 2003
pp. 4
This paper presents the design of a system that supports execution of HLA distributed interactive simulations in an unreliable Grid environment. The design of the architecture is based on the OGSA concept that allows for modularity and compatibility with G...
