Past Research Groups
National Laboratory: We are working with Pavan Balaji, Brian
Skjerven, and Wesley Bland to explore the possibility of mapping
Chapel's runtime communication interface to MPI-3's features for
- BSC / UPC: We were pursuing a collaboration with Alejandro Duran of the Nanos++ Project to implement Chapel's tasking layer using Nanos++ user-level tasks.
- Carnegie Mellon University: We have worked with Franz Franchetti and Thom Popovici to study native support for FFT computations in Chapel and the suitability of Chapel as a portable parallel back-end language for the SPIRAL program generation system.
- Colorado State University: We have collaborated with Michelle Strout, Andy Stone, and Christopher Krieger to look at parallel programming patterns and support for tilings in Chapel.
- EPCC / U. Edinburgh: We supported a study undertaken by Michele Weiland and Thom Haddow to evaluate the performance of Chapel's task-parallel features on a single locale.
Fichtner and Alexey Gokhberg have explored the possiblity of
using Chapel for programming seismic wave propagation
- Indiana University: We are exploring extensions to Chapel's object-oriented features to support better interfaces (a la C++ concepts) with Jeremy Siek and Chris Wailes.
- LLNL/Rice University: We are collaborating with Tom Epperly, and Shams Imam on extending the Babel system for HPC language interoperability to support Chapel.
- ORNL: We are
working with David Bernholdt and
Tiffany Mintz, who are exploring the notion of
"programmer-guided reliability" in Chapel as a means of
detecting and correcting silent data corruption in applications.
- ORNL: We work with a number of scientists in the Computer Science Research, Extreme Scale Systems Center, and Future Technologies groups to evaluate Chapel for applications of interest such as MADNESS.
- ORNL / Notre Dame: We were involved in a study with Srinivas Sridharan, Jeffrey Vetter, and Peter Kogge to look at asynchronous software transactional memory (STM) on distributed memory architectures in the context of Chapel.
- OSU: We worked with Gagan Agrawal and Bin Ren, to look at using Chapel's user-defined reductions to target data-intensive computations using their FREERIDE technology as a back-end. This resulted in a paper at HIPS 2011 and a poster at LCPC 2010.
Sarkar, Sagnak Tasirlar, Shams Imam, and Philippe Charles
are looking into adding support for futures to Chapel as well
as general improvements to its task parallel features.
- University of
Delaware: Stephen Siegel,
Timothy Zirkel, and Timothy McClory are investigating the use
of model checking and symbolic execution to verify Chapel
- UIUC: We worked with Vikram Adve and Robert Bocchino to study Software Transactional Memory (STM) concepts for distributed memory architectures (see Software Transactional Memory for Large-Scale Cluters from PPoPP'08 for our initial results: paper, slides).
- UIUC: We are working with David Padua, Maria Garzaran, and Albert Sidelnik to investigate the use of Chapel to program GPU accelerators.
- University of Malaga: We are working with Rafael Asenjo, Maria Angeles Navarro, Rafael Larrosa Jimenez, and Alberto Sanz on parallel I/O, bulk-copy optimizations and redistribution, and dynamic self-scheduling iterators.
- University of Tokyo, Taura Lab: We have collaborated with Kenjiro Taura and Jun Nakashima on lightweight threading via MassiveThreads and performance evaluation of Chapel idioms.
- University of Oregon / Paratools Inc.: With Sameer Shende and Allen Malony, we are exploring the possibility of using Tau to analyze the performance of Chapel programs.
- UT Austin: With Calvin Lin and Karthik Murthy we explored possible memory consistency models for use in Chapel.
