The 9th International Workshop on Parallel Matrix Algorithms and Applications (PMAA16) will be held in Bordeaux (France) and will run from July 6 to 8, 2016.

The workshop aims at being a forum for an exchange of ideas, insights and experiences in different areas of parallel computing (Multicore, Manycores and GPU) and applications in which matrix algorithms are employed. The PMAA16 workshop will bring together experts and researchers from diverse disciplines with a common interest in matrix computation. The purpose of the workshop is to discuss recent developments in various aspects of parallel matrix algorithms and to bring together mathematicians, computational scientists and engineers.

The workshop will focus on:

  • Parallel methods for solving large sparse or dense linear systems of equations.
  • Parallel eigenvalue and singular value computations.
  • Automatic tuning and performance modeling.
  • Novel architectural paradigms (e.g. accelerator and multicore) and their use in matrix computations and applications.
  • Large scale scientific applications from diverse fields which have an emphasis on parallel matrix computation.

We invite you to submit scientific contributions in all fields of numerical analysis, scientific and industrial applications, software development, and high performance computing. From the submissions received, the Organizing Committee will select papers to be presented as oral contributions. We hope that this opportunity to present and discuss science will interest you, and we look forward to seeing you in Bordeaux! Papers presented at the PMAA16 and submissions on closely related topics will be considered for publication in a special issue of of Parallel Computing after a peer review process. They must be submitted electronically via Elsevier’s online submission system at

CSCS-USI Summer School on Effective High Performance Computing

The Swiss National Supercomputing Centre ( and the Institute of Computational Science ( at Università della Svizzera italiana are pleased to announce the opening of the selection process for participation in the annual Summer School. The Summer School will be held from July 17 through July 28, 2016, in Hotel Serpiano (, located in the Italian area of Switzerland. The hotel is positioned on Mount San Giorgio, UNESCO World Heritage site since 2003, wherefrom participants can enjoy an incredible view of Ceresio lake and its surroundings.

The Summer School will focus on the effective exploitation of High Performance Computing (HPC) systems, more details on the agenda can be found on our webpage:

Please see the flyer in attachment and the youtube video from the 2015 Summer School:


The Summer School is dedicated to Master and Ph.D. students, academic staff and professionals. Applicants have to match the following requirements:

  • Good knowledge of at least one of the following programming languages: C++, C, or Fortran 90
  • Familiarity with the UNIX/Linux OS and the basic programming environment tools (terminals, editors, compilers)
  • Require HPC skills for their work or research.

Only applicants who satisfy all requirements will be considered. Participants will need to bring their own laptop for practical sessions.

###CONTENT The school will focus on the effective exploitation of High Performance Computing (HPC) systems. Current and coming generations of HPC systems are increasing in size and complexity. Multi-core processors, general purpose graphic accelerators (GPUs), many-cores accelerators (MIC), ultra-fast parallel storage devices, and high bandwidth low-latency networks are being combined to be used effectively for scientific and technical computing. On suitable classes of algorithms, outstanding performance can be achieved with power efficiency significantly higher than traditional architectures, considerably minimising overall times-to-solution of high-end scientific problems. An efficient usage of such hybrid architectures is not a trivial task, often requiring a full redesign and refactoring of the code in order to expose those features that can be optimally exploited by a given hardware component, as massively parallel algorithmic components, that can be effectively accelerated by the GPU, or overlapping computation and communication in order to scale on thousands of CPUs. Traditional parallel programming approaches, based on the message-passing paradigm, are no longer sufficient to fulfil this task, and innovative solutions need to be addressed.

During the two weeks of the school a number of such solutions will be presented. The MPI, OpenMP, CUDA, OpenACC programming models will be introduced, together with scientific libraries and efficient I/O and data visualisation solutions and optimisation techniques. Their effective combined usage, in order to achieve an ideal exploitation of large hybrid architectures, will be discussed and experimented with extensive practical and exercise lab sessions to help clarify and consolidate the theoretical material presented.

The following topics will be covered:

  • Message passing programming model and the MPI standard
  • Shared memory systems and the OpenMP programming model
  • Scientific libraries
  • MPI I/O and other solutions for efficient data reading and writing
  • GPU programming with CUDA and OpenACC
  • Code optimization
  • Scientific visualisation

###APPLICATION PROCESS If you meet all requirements, please download the application form ( fill it in, and send it to [email protected] no later than Sunday, April 11, 2016. Thirty applicants will be selected to participate in the Summer School. You will be notified about acceptance or rejection of your application by Monday, April 27, 2016. Those candidates whose application successfully passes the selection process will receive further information regarding the registration.

Graduate Student Modeling Workshop (IMSM 2016)

The 22nd Industrial Mathematical & Statistical Modeling (IMSM) Workshop for Graduate Students will take place at North Carolina State University, 17-27 July 2016. The workshop is sponsored by the Statistical and Applied Mathematical Science Institute (SAMSI) together with the Center for Research in Scientific Computation (CRSC) and the Department of Mathematics at North Carolina State University.

The IMSM workshop exposes graduate students in mathematics, engineering, and statistics to exciting real-world problems from industry and government. The workshop provides students with experience in a research team environment and exposure to possible career opportunities. On the first day, a Software Carpentry bootcamp will bring students up-to-date on their programming skills in Python/Matlab and R, and introduce them to version control systems and software repositories.

Local expenses and travel expenses will be covered for students at US institutions. The application deadline is 15 May 2016. Information is available at and questions can be directed to [email protected]
