With increasing heterogeneity in both computational devices and memory
organization in high performance computing platforms, movement of data
between devices and layers of memory has become a critical challenge
for science and engineering users of these platforms. Imminent arrival
of exascale platforms has brought these concerns to the forefront.
The objective of this workshop is to understand the impact of
abstractions and tools that have been around for some time and have
seen some adoption.

COLOC is a joint workshop of EuroPar 2021.

Areas or research interest include, but are not limited to:

-Modeling node topology
-Modeling network and communication
-Performance analysis of application to understand affinity
-Affinity metrics
-Runtime support for extracting affinity from application
-Code analysis in order to understand communication pattern
-Algorithm to improve locality
-Language, abstraction and compiler support for data locality
-Data structure and library support to better manage memory access
-Runtime-system and dynamic locality management
-System-scale locality optimization
-Validating locality optimization at thread or process level
-Memory management
-Locality management in large-scale application
-Impact of Locality to application

The COLOC workshop seeks contribution targeting (i) methods and tools
to understand hierarchical topology that describes the characteristics
of platform resources (ii) abstractions and tools to better manage
data placement, thereby maximize application performance, and (iii)
validating data-locality optimization, using applications from
different domains. The aim of this workshop is to bring together
researchers who are either developing tools, or using them to enhance
performance through the use of  locality and topology.  Of particular
interest are case studies that highlight the impact of using these
tools and abstraction. While high-performance computing is our primary
focus,  contributions on data locality and energy efficiency, data
locality in the context of Big Data or deep learning applications are
also of great interest.

Targeted audience
HPC application developers interested in exploring new ways to
optimize their code.
HPC centers and clusters managers to enhance cluster usage and
application efficiency.
Academics and researchers in scientific computing.

What and how to submit a paper

Paper, in PDF format, should be submitted to the workshop easychair
submission site (link TBA). Papers should be formatted according to
the LNCS style that can be downloaded from the springer website. Page
limit is 12. It includes everything (text, figures, references) and
will be strictly enforced by the submission system. Complete LaTeX
sources must be provided for accepted papers. Papers should be typeset
using the single column format. All submitted research papers will be
peer-reviewed. Only contributions that are not submitted elsewhere or
currently under review will be considered. Authors of accepted papers
will have to sign a Springer copyright form. Short papers (2-4 pages)
are also accepted submission. However, only paper which camera-ready
version longer than 10 pages will be included in the proceedings
published by Springer in the ARCoSS/LNCS series. Accepted paper will
be presented during the workshop session of the Euro-Par 2021
conference in Lisbon Portugal.
