Call For Papers


The availability of commodity PCs/workstations and high-speed networks at low prices enabled the development of low-cost clusters. These clusters are being targeted for supporting the traditional high-end computing applications as well as emerging applications, especially those requiring high-performance servers. Designing high-performance and scalable clusters for these emerging applications requires design and development of high-performance communication systems, low-overhead programming environment support and support for Quality of Service (QoS). New user-level communication protocol standards such as Virtual Interface Architecture (VIA) and InfiniBand Architecture (IBA) are providing exciting ways to design high-performance communication architectures for clusters.

A large number of research groups from academia, industry, and research labs are currently engaged in the above research directions. The goal of this workshop is to bring together researchers and practitioners working in the areas of communication and architecture to discuss state-of-the-art solutions as well as future trends for designing scalable, high-performance, and cost-effective communication architectures for clusters.


Topics of interest for the workshop include but are not limited to:
  1. Router/switch, network, and network-interface architecture for supporting efficient point-to-point and collective communication at intra-cluster and inter-cluster levels.
  2. Design, development, and implementation of user-level communication protocols (GM, VIA, etc) on different networking and interconnect technologies (such as Myrinet, Gigabit Ethernet, ATM, Infiniband, etc.).
  3. High-performance implementation of different programming layers (Message Passing Interface (MPI), Distributed Shared Memory such as TreadMarks, Get/Put, Global Arrays, sockets, etc.)
  4. Communication and architectural issues related to flow control, management of communication resources, deadlock-handling, reliability, and QoS.
Results of both theoretical and practical significance will be considered.


The proceedings of this workshop will be published together with the proceedings of other IPDPS '01 workshops by IEEE Computer Society Press.


The authors of the best papers in the workshop will be invited to submit extended versions of their work to a special issue of `Cluster Computing' journal. Direct submission of high-quality work to the special issue will also be possible.


We are planning a purely electronic submission and review process. Authors are requested to submit papers (in PDF format) not exceeding 10 single-spaced pages, including abstract, five key words, contact address, figures, and references. E-mail your manuscripts to:

Note: the PDF file must be viewable using the ``acroread'' tool. It is also important, when creating your PDF file, to use a page size of 8.5x11 inches (LETTER sized output not A4), since an A4 sized page may be truncated on a LETTER sized printer.


Paper submission:           October 16, 2000  (Extended to Oct 23, 2000) 
Notification of acceptance: December 11, 2000 
Camera-ready due:           January 22, 2001
