This is a continuation of the succesful MTAAP'07 Workshop held last year in Long Beach, CA.


Multithreading (MT) programming and execution models 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 profileare Cray's XMT, IBM Cyclops, and several SMT processors from Sun (UltraSparc T1&T2), IBM (Power5+, Power6), 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. 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 MT languages and libraries, compilers, analysis and debugging tools to increase the programming productivity.
