Found in: Computing in Science and Engineering
By Hans-Joachim Bungartz, Donald Estep, Ulrich RĂ¼de, Peter Turner
Issue Date:November 2009
pp. 5-11
<p>This year's SIAM CSE conference featured a structured program on education that sought to attract attention to and sustained interest in this essential topic.</p>
Plenary Talks
Found in: 2011 10th International Symposium on Parallel and Distributed Computing (ISPDC 2011)
By Hans-Joachim Bungartz
Issue Date:July 2011
pp. xv-xvi
These keynote lectures discuss the following: challenges in advanced computing - multi-this and multi-that; and practical methodologies of co-design for exascale systems and applications.
Invasive Compute Balancing for Applications with Hybrid Parallelization
Found in: 2013 25th International Symposium on Computer Architecture and High Performance Computing (SBAC-PAD)
By Martin Schreiber,Christoph Riesinger,Tobias Neckel,Hans-Joachim Bungartz
Issue Date:October 2013
pp. 136-143
Achieving high scalability for dynamical adaptive algorithms in HPC is a non-trivial task. In this contex, explicit data migration is typically applied which comes with several challenges such as criteria when and where to migrate data or additional bandwi...
From GPGPU to Many-Core: Nvidia Fermi and Intel Many Integrated Core Architecture
Found in: Computing in Science and Engineering
By Alexander Heinecke,Michael Klemm,Hans-Joachim Bungartz
Issue Date:March 2012
pp. 78-83
Comparing the architectures and performance levels of an Nvidia Fermi accelerator with an Intel MIC Architecture coprocessor demonstrates the benefit of the coprocessor for bringing highly parallel applications into, or even beyond, GPGPU performance regio...
Parallelizing a Black-Scholes solver based on finite elements and sparse grids
Found in: Parallel and Distributed Processing Workshops and PhD Forum, 2011 IEEE International Symposium on
By Hans-Joachim Bungartz,Alexander Heinecke,Dirk Pfluger,Stefanie Schraufstetter
Issue Date:April 2010
pp. 1-8
We present the parallelization of a sparse grid finite element discretization of the Black-Scholes equation, which is commonly used for option pricing. Sparse grids allow to handle higher dimensional options than classical approaches on full grids, and can...
First Experiences with Group Projects in CSE Education
Found in: Computing in Science and Engineering
By Martin Bernreuther, Hans-Joachim Bungartz
Issue Date:July 2006
pp. 16-25
The various educational workshops at CSE-related conferences reveal that there is an ongoing open discussion on how to define the relevant aspects of this discipline, on how to integrate the identified topics into the curricula, and, of course, on how to d...
Shared memory parallelization of fully-adaptive simulations using a dynamic tree-split and -join approach
Found in: 2012 19th International Conference on High Performance Computing (HiPC)
By Martin Schreiber,Hans-Joachim Bungartz,Michael Bader
Issue Date:December 2012
pp. 1-10
In this work we present an approach for the parallelization of hyperbolic simulations on shared-memory architectures running on fully-adaptive grids. We tackle the parallelization problem with a dynamic sub-tree split- and join-approach by running computat...
Many-core architectures boost the pricing of basket options on adaptive sparse grids
Found in: Proceedings of the 6th Workshop on High Performance Computational Finance (WHPCF '13)
By Alexander Heinecke, Hans-Joachim Bungartz, Jacob Jepsen
Issue Date:November 2013
pp. 1-9
In this work, we present a highly scalable approach for numerically solving the Black-Scholes PDE in order to price basket options. Our method is based on a spatially adaptive sparse-grid discretization with finite elements. Since we cannot unleash the com...
Invasive computing in HPC with X10
Found in: Proceedings of the third ACM SIGPLAN X10 Workshop (X10 '13)
By Andreas Zwinkau, Christoph Riesinger, Gregor Snelting, Hans-Joachim Bungartz, Martin Schreiber
Issue Date:June 2013
pp. 12-19
High performance computing with thousands of cores relies on distributed memory due to memory consistency reasons. The resource management on such systems usually relies on static assignment of resources at the start of each application. Such a static sche...
A high-level Fortran interface to parallel matrix algebra
Found in: Proceedings of the Second International Conference on Computational Science, Engineering and Information Technology (CCSEIT '12)
By Alexei Matveev, Hans-Joachim Bungartz, Martin Roderus
Issue Date:October 2012
pp. 112-119
Scientific software often relies on complex vector- and matrix algebra, sometimes combined with more elaborate linear algebra problems, such as systems of linear equations or eigenvalue problems. Its efficient parallel computation is well studied, and ther...
