Fifth  Workshop on Models, Algorithms and Methodologies 

for Hybrid Parallelism in new HPC Systems


Bialystok, Poland, September 8-11, 2019



jointly with the

13th International Conference on Parallel Processing

and Applied Mathematics PPAM 2019








MAMHYP19 is the fifth workshop after the first four held in Torun ,
Warsaw, Krakow and Lublin in 2011, 2013, 2015 and  2017 respectively, jointly to the PPAM conferences. Since then, the development of efficient algorithms for HPC systems with multiple forms  of parallelism, is still a challenging problem.


More precisely, from an architectural point of view , a High Performance Computing system can  be described by means of a hybrid multi-level structure: at the highest level there are several systems connected among them by geographic networks (System level); an intermediate level is composed by the nodes in a single system communicating among them by means of dedicated fast networks or high performance switches (Node level); at the lowest level, finally, there are several computing elements, computing cores as well as graphic accelerators, sharing resources in a single CPU (Core level).


These architecture levels have very different features and they require different algorithmic development methodologies. For such a reason, the development of algorithms and scientific software for these system implies a suitable combination of several methodologies to deal with the different kinds of parallelism corresponding to each architectural level. The general aim is then the development of hybrid and hierarchical algorithms, able to be aware of the underlying platform. Main problems in this field are the management of large parallelism degree due to several computing units, the heterogeneity of these devices and the combination of the several kinds of parallelism in a single algorithm. These topics are mainly investigated also to gain the so called exascale performance, and, from another side, the high performance cloud computing, with regard to the so called Internet of Things and its interaction with HPC.

This workshop focuses specifically on Models, Methodologies, Algorithms and Environments to exploit all forms of parallelism and their combination at the all levels in the emerging HPC multicomputers, with the goal of gathering the current state of knowledge in the field.
