Second Workshop on Models, Algorithms and Methodologies
for Hierarchical Parallelism in new HPC Systems
sponsored by the Department of Mathematics and Applications - University of Naples Federico II (Italy)
Warsaw, Poland, September 8-11, 2013
jointly with the
10th International
Conference on Parallel Processing
and Applied Mathematics PPAM 2013
September 8, 2013: Chair prof. Giuliano Laccetti Introduces the Workshop
Background
MAMHIP13 is the second workshop after the
first one held in Torun
jointly with PPAM 2011
conference. 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 hierarchical 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.
