This year, the Research Papers Committee selected 17 research papers to be presented at the conference. For the Hans Meuer Award, the committee narrowed that list down to two candidates:
The work by Joseph Schuchart and José Gracia presents an approach to manage global task data dependencies in partitioned global address space (PGAS) applications. To do this, they overcame the lack of fine-grained synchronization communication in the PGAS model with fine-grained task synchronization across process boundaries. In the paper, they present how global data dependencies are used to describe the data flow between tasks and how interactions between distributed scheduler instances are used to manage those dependencies. The authors demonstrate the feasibility and scalability of this approach.
For the second paper, Ignacio Laguna, Paul C. Wood, Ranvijay Singh, and Saurabh Bagchi describe GPUMixer, a tool they developed to perform GPU-based mixed-precision floating-point tuning for scientific applications. While precision tuning techniques are available, they are mainly designed for serial programmes and are accuracy-driven. The GPUmixer, by contrast, uses a performance-based approach and employs multiple threads. The paper describes how this was accomplished and what kinds of performance gains they were able to achieve compared to state-of-the-art methods.
The authors of the both papers will be given the opportunity to present their work at the Research Paper Award Session on June 17, at which point the Research Papers Committee will decide which one is the best overall paper. The winner will be announced on June 18, during the Hans Meuer Award Ceremony.
The awarded authors will share a cash prize of 5000 euro and be given the opportunity to present a keynote talk on their work in one of the research paper sessions at the conference.
Sponsored by the Gauss Centre for Supercomputing, this year's winner of the GCS Award will be announced during the conference opening session by the ISC 2019 Research Papers chair, Dr.-Ing. Carsten Trinitis, and awarded on June 17, at the Research Papers Award Session by Professor Michael M. Resch, chairman of the GCS Award Committee.
This year's GCS Award winning research paper is titled End-to-end Resilience for HPC Applications, and is authored by Arash Rezaei, Harsh Khetawat, Onkar Patil, Frank Mueller, Paul Hargrove and Eric Roman.
The ISC 2019 early bird registration will be ending on May 8, 2019.
