2016 Copper Mountain Student Paper Competition

The 14th Copper Mountain Conference on Iterative Methods (March 20-25, 2016) invites submissions to the student paper competition, see

Any current student, or any recent PhD graduate whose degree was awarded after January 1, 2015, is eligible to submit a paper. Papers must contain original unpublished research due mainly to the student. These papers must be received before January 15, 2016. The student must be the primary author and the paper may be no more than 10 pages in length.

The paper must be emailed as an attachment in PDF format to and identified in the email as an entry for the 2016 student paper competition. In addition to emailing the paper, an abstract for the paper must be submitted through our Abstract Submission form. Sending only an abstract is unacceptable. A panel of judges will determine the best papers.

The Copper Mountain Conference offers reduced student registration rates and awards to pay for lodging and conference expenses for students, subject to NSF funding. Postdocs are not they eligible for student registration fees or lodging support. Students seeking support should email the conference coordinator, Annette Anthony,, for more information.

The 2016 conference also features a Workshop on Iterative Linear Algebraic Data Mining Techniques Workshop (Sunday, March 20 - Tuesday, March 22), which may be of special interest to students, see

SIAM Workshop on Combinatorial Scientific Computing 2016 (CSC16)

With the continuing advances in high-performance computing, the role of computational science and engineering (CSE) has extensively grown in importance over the last decades. At the same time scientific simulations continue to face a number of challenges and generate massive amounts of data. Many of the underlying problems here are combinatorial in nature and unified by a common set of abstractions, data structures, and algorithms, often based on graphs and hypergraphs. On a related front, data science and analytics have emerged as powerful methods of inquiry across a broad range of domains and pose various fundamental challenges associated with size and complexity of data that would greatly benefit from combinatorial methods. CSC16 provides a forum for researchers interested in the interaction of combinatorial mathematics and algorithms with CSE and/or data science.

CSC16 follows five successful CSC workshops held roughly biennially since 2004. A new feature of CSC16 is that there will be a peer-reviewed proceedings associated with the workshop. The proceedings will be published by SIAM and hosted at its platform The papers will be made permanently available with DOI links. SIAM proceedings are indexed by major scientific bibliography databases.

Authors are invited to submit manuscripts that present original unpublished research in all areas of combinatorial scientific computing. Topics of interest include, but are not limited to,

  • Combinatorial (discrete) models in scientific computing
  • Graph and hypergraph algorithms in scientific computing
  • Sparse matrix computations
  • Combinatorial problems in data science and network science
  • Combinatorial problems in Algorithmic Differentiation
  • Combinatorial problems in optimization
  • Applications of combinatorial scientific computing

Types of Submissions

We invite two types of submissions.

  1. Full Papers. Papers should not exceed ten (10) pages using double-column format and 11 pt font size. The SIAM macro to be used for paper preparation is available at Accepted papers will be included in the proceedings, which will be published electronically by SIAM at its proceedings platform. Accepted papers will be presented at the workshop as talks.

  2. Extended Abstracts. Abstracts should not exceed 2 pages using double-column format and 11 pt font size. Accepted abstracts will be presented as talks at the workshop, but will not be published in the proceedings.

Important Dates

Submission deadline (for both papers and abstracts): May 2, 2016, 11:59pm PDT.
Notification of Acceptance: July 5, 2016.

Submission will be handled through EasyChair (
Specific link for submission will be provided later.

Postdoc positions at the International Centre for Theoretical Sciences

The International Centre for Theoretical Sciences (ICTS), Tata Institute of Fundamental Research (TIFR) is inviting applications for postdoctoral positions ( in theoretical physics, interdisciplinary and applied mathematics, computational science, astronomy, theoretical physical chemistry, theoretical physical biology and related fields. Individuals who have submitted their doctoral thesis are also encouraged to apply. The positions are nominally for two years from the time of joining with possibility of extension for the third year. In addition to regular positions, ICTS offers prized postdoctoral fellowship positions (SIMONS: and AIRBUS: for highly deserving candidates.

How to Apply

Interested candidates can apply online at: with their CV, list of publications, a research proposal (not more than two pages) and a covering letter (PDF). The applicants also need to arrange at least three recommendation letters sent directly to the ICTS. The nominal deadline is December 15, 2015; but applications will be considered until the positions are filled. The nominal starting date of September 1, 2016 is negotiable. Informal queries may be addressed to the ICTS faculty.

Deadline: December 15, 2015

PhD student positions in fault tolerant linear algebra

The research group Theory and Applications of Algorithms at the University of Vienna (UV) and the research group Parallel Computing at Vienna University of Technology (TU) have three openings for PhD students (two of them at UV, one at TU) in a joint research project on resilient and fault tolerant algorithms in numerical linear algebra (with co-PIs Wilfried Gansterer and Jesper Larsson Traeff).

All positions require a first-rate Master or Dipl.-Ing. degree in computer science, computer engineering, or a closely related field with a focus on algorithms and data structures, discrete mathematics and linear algebra, computer systems, parallel computing, and programming. Moreover, strong analytical skills, solid software development and programming skills, parallel computing experience (shared and/or distributed memory, programming models, interfaces, algorithms), demonstrated written and oral communication skills, effective interpersonal skills, a background in high performance computing (HPC), in dense numerical linear algebra, and in fault-tolerance for parallel and distributed computing systems are required. The working language is English.

Each position is for three years. Expected starting date is March 1st,

  1. Applications received by January 15th, 2016 will receive full consideration.
