Background

MAMHYP15 is the Third workshop after the first two held in Torun and Warsaw in 2011 and 2013

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.
