Theme
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:
- Multithreaded Architectures
- Heterogeneous architectures
including graphics processors and other architectures
- Multithreaded Programming
Framework
- Compilation and Optimization
for MT and heterogeneous architectures
- Multithreaded Performance
Analysis and Debugging Tools
- Multithreaded Performance
Metrics and Evaluations
- Multithreaded Libraries and
run-time systems
- Innovative applications for MT
architectures
The MTAAP workshop proceedings will
be published along with the IPDPS proceedings.

Call for Papers
Paper Submission
Guidelines
Submitted
manuscripts may not exceed 15 single-spaced pages using 12-point size font on
8.5x11 inch pages, including figures, tables, and references. Please use the
standard 1-inch margin. Authors may submit additional material as an appendix
to their submission, but there is no guarantee that this material will
influence the review process. Manuscripts must be submitted electronically and
in 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.
Accepted papers will have a page limit of 10
pages, and authors can purchase an additional 2 pages, for a total of 12 pages
maximum.
MTAAP submissions are being handled by EDAS
system. To submit a paper, please use the following link (MTAAP EDAS) and follow the
instructions.
