Workshop - Unconventional Cluster Architectures and Applications (UCAA) 2012

The workshop on Unconventional Cluster Architectures and Applications aims at creating the right atmosphere for a discussion of opportunities in cluster computing. In this regard, contributions would not only be accepted according to their technical merits but also according to their contribution to this discussion.

The main motivation for the unconventional topic of the workshop is that in the near past we have seen that many unconventional and disruptive techniques and approaches, used in specialized cluster computing, have later become pervasive. Probably, the most prominent example today is certainly GPU Computing. GPUs, initially used only in the video gaming market, have been later widely used for accelerating computations due to their extraordinary parallelism. However, the use of GPUs for acceleration purposes was very uncommon at the beginning, although it is almost standard today. Thus, if the UCAA workshop would have taken place during the early stages of GPGPU, contributions on the use of GPUs for accelerating code execution would have perfectly fit the workshop topic. Other examples of such unconventional use of existing resources may include papers that argue that the current trend at the software level is clearly virtualization (for consolidation of hardware) that spawns across different nodes of a cluster. At the hardware level, other contributions could argue that the trend is disaggregation of resources like memory, I/O devices, and even cores, so that they can be recomposed in many different ways. This would further increase later consolidation opportunities. Other authors could propose that global address spaces are a mechanism to disaggregate memory and recombine it later across nodes, proposing the hardware and software infrastructure to do so.

Notice that these proposals may rather be reflective of a broader industry trend.

As can be seen, work on disruptive approaches is encouraged. The broad scope of the workshop facilitates submissions on unconventional uses of hardware or software, trying to gather new ideas in the context of clusters.
