Workshop - Heterogeneous and Unconventional Cluster Architectures and Applications (HUCAA) 2015

The fourth edition of the HUCAA workshop ( is going to take place in conjunction with IEEE Cluster 2015 (, September 8, 2015, Chicago, IL, USA. 


The workshop will take place September 8: We're looking forward to seeing you at this venue!


The workshop on Heterogeneous and Unconventional Cluster Architectures and Applications gears to gather recent work on heterogeneous and unconventional cluster architectures and applications, which might have an impact on future mainstream cluster architectures. This includes any cluster architecture that is not based on the usual commodity components and therefore makes use of some special hard- or software elements, or that is used for very special and unconventional applications. In particular we call for GPUs and other accelerators (Intel MIC/Xeon Phi, FPGA) used at cluster level. Even though accelerators are already used pervasively, we still see many unconventional and even disruptive uses of them. 

This year, we especially call for methods, techniques and best practices to improve the energy efficiency of cluster computing. This includes for instance specialized hardware and power-/energy-aware software layers. Power consumption is a hard constraint, and predictions show that this trend will not revert in the future. For the nascent field of power- and energy-aware computing, we see a large need in sharing experiences, best practices and new ideas.

Note that papers submitted to this topic will be preferred given equal scores with other contributions. However, HUCAA also welcomes contributions on other topics (examples see below). Also, proposals may rather be reflective of a broader industry trend; in general contributions are not only accepted based on their technical merits but also according to their contribution to the discussion on how cluster computing might evolve in the future.

Topics of Interest

This year, HUCAA in particular calls for:
  • New methods and techniques for improved energy efficiency
Papers submitted to this topic will be preferred given equal scores with other contributions. However, HUCAA still welcomes contributions to other topics, including:
  • Clustered GPUs, Xeon Phis or other accelerators
  • Runtimes for heterogeneous cluster architectures
  • New industry and technology trends and their potential impact 
  • High-performance, data-intensive, and power-aware computing
  • Communication methods for distributed or clustered accelerators
  • Application-specific cluster and datacenter architectures
  • Emerging programming paradigms for parallel heterogeneous computing
  • Software cluster-level virtualization for consolidation purposes
  • Hardware techniques for resource aggregation
  • New uses of GPUs, FPGAs, and other specialized hardware

    Paper Submission Guidelines

    Published papers will appear in the conference proceedings.

    Submissions may not exceed 8 pages in PDF format including figures and references, and must be formatted in the 2-column IEEE format. Submitted papers must be original work that has not appeared in and is not under consideration for another conference or journal. Work in progress is welcome, but first results should be made available as a proof of concept. Submissions only consisting of a proposal will be rejected. 

    Templates are available on the main conference website:

    Submissions are handled by EasyChair:


    HUCAA was previously co-located with ICPP (2012-2014). Due to HUCAA's strong focus on cluster architectures we decided to move to IEEE Cluster for 2015.
