As we look forward to the exascale era, heterogeneous parallel machines are expected to play a massive role in architecting the largest systems in the world. While there is significant interest in these architectures, much of this interest is an artifact of the hype associated with them. Such hype is often resulted from the study of a set of computation kernels. However, without understanding the behavior of detailed kernels or even entire applications on these architectures, it is unclear how future systems would be designed based on these architectures.

For heterogeneous parallel machines to truly be a successful High Performance Computing platform, it is important that we obtain a complete picture of HPC applications and learn the opportunities and challenges these architectures raise. This workshop aims at providing a platform where the characteristics of computational kernels and applications, and how different software stacks impact them, are presented to the research community to guide future heterogeneous HPC system designs.

The goal of this workshop is to bring together researchers and practitioners who are involved in application characterizations for heterogeneous exascale systems, to discuss their ongoing research as well as future trends in these designs.

SUBMISSIONS
-----------
We solicit papers on all aspects of HPC application studies, especially those that involve accelerators such as GPUs, FPGAs, etc. The topics include (but are not limited to):

* Categorizing/characterizing of HPC applications and kernels with
respect to patterns in computation structure, communication, cache
accesses, memory, I/O, and file accesses.

* Evaluating the importance of individual kernels within an entire
application.

* Modeling for applications running on accelerator-based heterogeneous
HPC systems.

* Implication of workload characterization in heterogeneous design issues.

* Benchmarking of applications, kernels or software stacks and tools
supporting applications.

Submitted manuscripts are expected to be within 8 pages and should be formatted using the ACM SIG Proceedings alternate style (single-spaced, double-column format). All papers will be subjected to blind reviews. The submission site is
