Conference 

Euro-Par is the prime European conference covering all flavors of parallel and distributed processing:

• from theory to practice, 
• from multi-core processors to accelerators, supercomputers and clouds, 
• from fundamental algorithmic problems to systems and tools,
• from applications in computational sciences to machine learning and artificial intelligence.

Euro-Par proceedings are published by Springer in the LNCS series.

The main audience of Euro-Par are the researchers in academic institutions, government laboratories and industrial organisations. Euro-Par's objective is to be the primary choice of such professionals for the presentation of new results in their specific areas. Euro-Par’s unique organization into topics provides an excellent forum for focused technical discussion, as well as interaction with a large, broad and diverse audience. In addition, Euro-Par conferences provide a platform for a number of accompanying, technical workshops for smaller and emerging communities.

This call for conference papers will be followed by a separate call for workshop papers (in February 2020) and for posters for the doctoral symposium (in March 2020).

Many areas of science, industry, and commerce are producing extreme-scale data that must be processed — stored, managed, analyzed — in order to extract useful knowledge. This topic seeks papers in all aspects of distributed and parallel data management and data analysis.

Topic 6: Cluster, Cloud and Edge Computing

Global Chair: María S. Pérez, Universidad Politecnica de Madrid, Spain

Local Chair: Lukasz Dutka,  Academic Computer Centre Cyfronet AGH, Kraków, Poland

While the term Cluster Computing is hardware oriented and determines the organization of large computer systems at one location, the term Cloud Computing addresses the use of such large computer systems. Since Cluster and Cloud Computing complement each other, there are interdependencies between many research questions addressing these topics. In this Topic of EuroPar, we will particularly focus on these interdependencies in addition to the results specifically addressing issues belonging only to one of both areas.

In Cluster Computing, important research topics focus on performance, reliability, and energy efficiency as well as the impact of novel processor architectures. Since Cloud Computing tries to hide hardware and system software details from the users, research issues include various forms of virtualization and their impact on performance, resource management, and business models that address system owner and user interests.

Further, it is interesting to address Cloud Computing on top of several smaller clusters and its advantages with respect to reliability and load balancing on a high abstraction level as well as the consideration of networks.

Finally, the combination of local computer installation together with Cloud Computing, also referred to as ‘'fog/edge'' computing has received growing interest in recent time. This concept has led to many research questions, like an appropriate distribution of subtasks to the available systems under the consideration of various constraints.

Since many research studies in this area use experimental evaluation, we expect the authors reporting such studies to provide sufficient study details, if necessary complemented by a possibly web-based supplement, to allow a technical evaluation during the review process and reproducibility and replicability of results if the submission is accepted.

Focus

• Cloud-enabled applications and platforms
• Interoperability and portability in Cloud Computing
• Aggregation and federation of Clouds
• Hybrid, Fog and Edge computing
• Energy efficiency in Cluster and Cloud Computing
• Resource/Service/Information discovery in Clouds
• Resource management and scheduling in Clusters and Clouds
• Cloud programming models, tools, and algorithms
