Over the past few years, the focus of most workshops on exascale computing (defined as the use of computers capable of at least one quintillion calculations per second) has been the expected challenges of billion-way concurrency and the associated issues such as data motion, resilience, and energy usage.  Less attention has been paid to the mathematics at exascale. The focus of this workshop is on providing relevant, accessible and timely material on exascale computing and the mathematical challenges with many-core and accelerated architectures. The intent is that attendees come away with a reasonable idea of the current state of the art, the current challenges and opportunities, and what needs to be done differently going forward. This workshop, a synthesis of the state of the field, will be accessible to non-experts and experts alike.


Funding Agency


SIAM and the Workshop Organizing Committee wish to extend their thanks and appreciation to the U.S. National Science Foundation for its support of the Workshop.





The workshop will consist of a full day of contributed and invited presentations and discussions on topics including, but not limited to:

Case studies, position papers proposing topics for discussion, and technical talks describing particular approaches are invited. The organizers seek participants from a broad spectrum of areas, including developers of scientific simulation codes and industrial end users.  The presentations are expected to be 30 minutes in length, but we will entertain exceptions.

How to Participate

Those wishing to participate should submit an abstract or position paper by February 28, 2014.  Papers should be submitted through EasyChair at  Submissions should be no longer than 1000 words; no additional material other than a list of cited references will be considered. Use no smaller than 11-point font and at least one-inch margins. There is a limit of at most two submissions that an individual can submit; no limits on number of groups/institutions. Each paper should provide contact information (name, institution, email address) for a single, corresponding author. If you do not already have an account on EasyChair, you will be asked to go through the easy process to create one.

Notifications of acceptance will be sent by March 31, 2014.  Submissions will be selected based on their quality and responsiveness to the call. We expect to post a list of the selected papers online with the agenda. Participants will be expected to fund their own travel and accommodations for the workshop.
