ALCHEMY Workshop 2015
Held in conjunction with the International Conference on Computational Science (ICCS 2015)
Reykjavik, Iceland, 1-3 June 2015
The International Conference on Computational Science is an annual
conference that brings together researchers and scientists from mathematics
and computer science as basic computing disciplines, researchers from various
application areas who are pioneering computational methods in sciences such
as physics, chemistry, life sciences, and engineering, as well as in arts and
humanitarian fields, to discuss problems and solutions in the area, to identify new
issues, and to shape future directions for research.
Program
Program
Alchemy is scheduled in the ICCS conference program on the 1st of June.
Note to speakers: there is a 20-minute slot for each presentation (questions included), for both regular and short papers.

Raymond NAMYST, Université de Bordeaux, France
Raymond Namyst received his PhD from the University of Lille in
1997. He was lecturer at Ecole Normale Superieure de Lyon from 1998 to
2001. He became a full Professor position at University of Bordeaux in
september 2002.
These last ten years, he has been the scientific leader of the Runtime
Inria Research Group, devoted to the design of high performance runtime systems for parallel
architectures. His main research interests are parallel computing,
scheduling on heterogeneous multiprocessor architectures (multicore,
NUMA, accelerators), and communications over high speed networks. He
has contributed to the development of many significant runtime systems
(MPI, OpenMP) and most notably the StarPU software
(http://runtime.bordeaux.inria.fr/StarPU/).
He has been member of numerous conference program
committees. He was the co-chair of the Euro-Par 2011 international
conference, and has served as a topic chair for SC'11 and Euro-Par'14.
He has been involved in several European Exascale activities,
including the European Exascale Software Initiative (EESI) for which
he was coordinator of the Runtime System roadmap, and the European
Technology Platform for High Performance Computing (ETP4HPC).
Programming heterogeneous, manycore machines: a runtime system's perspective
Heterogeneous manycore parallel machines, mixing multicore CPUs with manycore accelerators provide
an unprecedented amount of processing power per node. Dealing with such a large number of
heterogeneous processing units -- providing a highly unbalanced computing power -- is one of the biggest
challenge that developpers of HPC applications have to face. To Fully tap into the potential of these
heterogeneous machines, pure offloading approaches, that consist in running an application on host cores
while offloading part of the code on accelerators, are not sufficient.
In this talk, I will go through the major software techniques that were specifically designed to harness
heterogeneous architectures, focusing on runtime systems. I will discuss some of the most critical issues
programmers have to consider to achieve portability of performance, and how programming languages may
evolve to meet such as goal.
Eventually, I will give some insights about the main challenges designers of programming environments will
have to face in upcoming years.

Call for papers
Call for papers
Massively parallel processors have entered high performance computing
architectures, as well as embedded systems. In June 2014, the TOP500
number one system (Tianhe-2) features the 57-core Intel Xeon Phi
processor. The increase of the number of cores on a chip is expected
to rise in the next years, as shown by the ITRS trends: other examples
include the Kalray MPPA 256-core chip, the 63-core Tilera GX processor
and even the crowd-funded 64-core Parallella Epiphany chip. In this
context, developers of parallel applications, including heavy
simulations and scientific calculations will undoubtedly have to cope
with many-core processors at the early design steps.
In the two past sessions of the Alchemy workshop, held together with
the ICCS meeting, we have presented significant contributions on the
design of many-core processors, both in the hardware and the software
programming environment sides, as well as some industrial-grade
application case studies. In this 2015 session, we seek academic
and industrial works that contribute to the design and the
programmability of many-core processors.
Topics
Topics
Topics include, but are not limited to:
* Programming models and languages for many-cores
* Compilers for programming languages
* Runtime generation for parallel programming on manycores
* Architecture support for massive parallelism management
* Enhanced communications for CMP/manycores
* Shared memory, data consistency models and protocols
* New operating systems, or dedicated OS

(experiments with Adapteva Epiphany, Intel Phi, Kalray MPPA, ST
STHorm, Tilera Gx, TSAR..etc)
Submission
Submission
This yea
r, there will be two formats for the presentation at the workshop. The usual full-length paper is 10 pages according to the ICCS format, and the short-paper format well fitted for works in progress, with a maximum of 2 pages. The accepted papers for full-length paper will be published alongside with the ICCS proceedings in Procedia Computer Science, whereas the short-papers will be presentation and poster only at the conference (with proceedings and presentations available from the workshop website). The manuscripts of up to 10 pages, written in English and formatted according to
the EasyChair templates, should be submitted electronically.
Templates are available for download in the Easychair right-hand-side menu
in a “New submission” mode.
