                               Heterogeneity in Computing Workshop

               in conjunction with IPDPS 2013, May 20, 2013, Boston, 
Massachusetts USA

sponsored by the IEEE Computer Society, through the Technical Committee 
on Parallel Processing (TCPP)

Heterogeneity is an important property of most modern computing systems. 
It is a consequence of the richness of current computing environments 
with their pronounced diversity in resources and requirements. 
Recognizing and efficiently exploiting this diversity in an integrated 
and coherent manner are key goals of heterogeneous computing.

On the one hand, heterogeneous computing systems have a range of diverse 
hardware resources that can be on a chip, within a computer, or on a 
local or geographically distributed network. Due to the rapid 
development of heterogeneous multi-core chips and the pervasive use of 
networks by all segments of society, the number and types of 
heterogeneous computing resources are growing rapidly. This growth 
creates the need and opportunity for new research to effectively utilize 
these resources in innovative and novel ways. For example, cluster 
computing, grid computing, peer-to-peer computing, and cloud computing 
all involve elements of heterogeneity. On the other hand, computing 
systems are often characterized by a variety of software resources that 
may or may not be coupled with specific hardware carriers. The effective 
implementation of efficient applications in these environments requires 
that a host of new concerns be addressed as these issues simply do not 
occur in homogeneous systems.

Whereas many researchers and practitioners that use computers have a 
peripheral awareness of heterogeneity in their respective fields, few 
critically approach their fields from the heterogeneous perspective. 
This is not particularly surprising, because each field has its own 
unique challenges and imperatives that propel investigations in search 
of solutions to pressing problems. However, addressing computing 
problems from the heterogeneous perspective offers at least three 
advantages: (i) the design and development of more advanced 
high-performance computing platforms, (ii) insight into new solution 
approaches, and (iii) exposure to new research opportunities and 
relationships among distinct research areas. HCW encourages the 
examination of both hardware and software systems from the perspective 
of heterogeneity.

With the increasing number of components in parallel and distributed 
systems, failure is becoming a critical factor that impacts application 
performance. Due to the differences in the components of heterogeneous 
computing systems, failure handling is particularly challenging in these 
systems. This is especially true for petascale or even exascale systems 
and the corresponding applications. Such systems employ heterogeneous 
multicores, various accelerators (such as GPUs), deeper memory 
hierarchies, and heterogeneous and hierarchical communication networks. 
Applications on these large-scale systems are expected to run for a 
significant amount of time and therefore are likely to encounter several 
failures during their runtime. This year, HCW is specifically 
encouraging (but not limiting to) submissions that explore paradigms, 
algorithms, and techniques for the management of such high performance 
heterogeneous computing systems and applications.
