MTAAP 2011


Workshop on Multithreaded Architectures and Applications

May 20, 2011
Anchorage, Alaska USA


To be held in conjunction with the
25th IEEE International Parallel & Distributed Processing Symposium

Description: IPDPS Logo



Multithreading (MT) programming and execution models, as well as hybrid programming with accelerated architectures, are starting to permeate the high-end and mainstream computing scene. This trend is driven by the need to increase processor utilization and deal with the memory-processor speed gap. Recent and upcoming examples architectures that fit this profile are Cray's XMT, IBM Cyclops, and several SMT processors from Sun (Victoria Falls), IBM (Power6, Power7), or Intel, as well as heterogeneous systems with accelerators such as GPGPUs from ATI, NVIDIA, and Intel. The underlying rationale to increase processor utilization is a varying mix of new metrics that take performance improvements as well as better power and cost budgeting into account. Yet, it remains a challenge to identify and productively program applications for these architectures with a resulting substantial performance improvement.

The MTAAP 2011 workshop is a full-day meeting to be held at the IPDPS 2011 focusing on Multithreading architectures and applications. This workshop intends to identify applications that are amenable to MT and the MT programming and execution models as well as the underlying architectures on which they can thrive. The workshop seeks to explore programming frameworks in the form of languages and libraries, compilers, analysis and debugging tools to increase the programming productivity. Topics of interest, of both theoretical and practical significance, include but are not limited to:

The MTAAP workshop proceedings will be published along with the IPDPS proceedings.
