This is a continuation of the succesful MTAAP series of workshops held since 2007.


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.

Topics of Interest

Topics of interest are guided by their application impact and include but are not limited to following topics:

Results of both theoretical and practical significance will be considered.

Final Agenda


The proceedings of this workshop will be published together with the proceedings of other IPDPS 2009 workshops by the IEEE Computer Society Press.

Paper Submissions 

Submitted manuscripts may not exceed 20 single-spaced pages using a 12-point font on 8½×11-inch pages, everything included (figures, tables, references, etc.). Manuscripts must be submitted electronically and in either PostScript or PDF format. Submissions will be judged on correctness, originality, technical strength, significance, quality of presentation, and interest and relevance to the workshop attendees. Submitted papers may not have appeared in or be under consideration for another workshop, conference, or journal.

MTAAP submissions are being handled by EDAS system. To submit a paper, please use the following link and follow the instructions.
