5th Workshop on Irregular Applications: Architectures and Algorithms (IA^3)
in conjunction with SC’15
Austin, TX, USA
November 15, 2015

Irregular applications span a broad range of applications with unpredictable
memory access patterns, control structures, and/or network transfers. They
typically use pointer-based data structures such as graphs and trees, often
present fine-grained synchronization and communication, and generally
operate on very large data sets. They have a significant degree of latent
parallelism, which however is difficult to exploit due to their complex
behavior. Current high performance architectures rely on data locality and
regular computation to tolerate access latencies, and often do not cope
well with the requirements of these applications. Furthermore, irregular
applications are difficult to scale on current supercomputing machines,
due to their limits in fine-grained synchronization and small data transfers.

Irregular applications pertain both to well established and emerging fields,
such as social network analysis, bioinformatics, semantic graph databases,
bioinformatics, Computer Aided Design (CAD) and computer security. Many
of these application areas also process massive sets of unstructured data,
which keep growing exponentially. Addressing the issues of irregular
applications on current and future architectures will become critical to
solve the scientific challenges of the next few years.

This workshop seeks to explore solutions for supporting efficient execution
of irregular applications in the form of new features at the level of the
micro- and system-architecture, network, languages and libraries, runtimes,
compilers, analysis, algorithms. Topics of interest, of both theoretical and
practical significance, include but are not limited to:

– Micro- and System-architectures
– Network and memory architectures
– Heterogeneous, custom and emerging architectures (GPUs, FPGAs,
multi- and many-cores, processors-in-memory)
– Modeling, simulation and evaluation of architectures
– Innovative algorithmic techniques
– Parallelization techniques and data structures
– Approaches for managing massive unstructured datasets
– Languages and programming models
– Library and runtime support
– Compiler and analysis techniques
– High performance data analytics, including graph databases

Besides regular papers, papers describing work-in-progress or incomplete
but sound, innovative ideas related to the workshop theme are also
encouraged. We solicit both 8-page regular papers and 4-page position
