MTAAP 2014

 

Workshop on Multithreaded Architectures and Applications

May 23, 2014
Phoenix, Arizona USA

 

To be held in conjunction with the
28th IEEE International Parallel & Distributed Processing Symposium

 

 

 

 

 

 

 

  Theme

Multithreading (MT) programming and execution models, as well as Many Integrated Core (MIC) and hybrid programming with accelerated architectures, are now part of the high-end and mainstream computing scene. This trend has been driven by the need to increase processor utilization and deal with the memory-processor speed gap. Recent and upcoming examples architectures and processors that fit this profile are Cray's XK and XMT, NVIDIA Kepler, Intel Phi, IBM Cyclops, and several SMT processors from IBM (Power7), AMD, or Intel, as well as heterogeneous clusters with accelerators from AMD and NVIDIA. 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 2014 workshop is a full-day meeting to be held at the IPDPS 2014 focusing on Multithreading Architectures and Applications. This workshop intends to identify applications that are amenable to MT, MIC, and hybrid 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 programmability. Topics of interest, of both theoretical and practical significance, include but are not limited to:

Call for Papers

Paper Submission Guidelines

Submitted manuscripts should follow the IEEE conference style: not exceed 12 single-spaced double-column pages using 10-point size font on 8.5x11 inch pages, including figures, tables, and references. Alternatively, authors can submit up to 15 single-spaced pages using 12-point size font on 8.5x11 inch pages, including figures, tables, and references. 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.
