Sriram Krishnamoorthy is one of many scientists reaching for the next step in supercomputer evolution, the exascale computer. In April 2013, DOE awarded him $2.5 million over five years to explore ways to advance exascale computing through their Early Career Research Program.
With the award, Sriram will pursue "Concrete Ingredients for Flexible Programming Abstractions on Exascale Systems," which will fundamentally transform exascale programming models and runtime systems for scientific applications via the design and characterization of algorithms that automate concurrency, data movement, and resilience management.
Sriram was one of 61 scientists to receive DOE Early Career Research Program funding in 2013 and the sole scientist from PNNL.
Dr. Sriram Krishnamoorthy will be a guest editor for a special issue of the Journal of Parallel and Distributed Computing, focusing on "Domain-Specific Languages and High-Level Frameworks for High-Performance Computing."
Submissions related to research on any aspect of domain-specific languages and high-level frameworks in the context of HPC, including frameworks applications, domain-specific languages and libraries, high-level data structures, high-level aspects of programming languages, or directive-based optimization approaches, are welcome.
Paper submissions will be accepted through Monday, July 15, 2013.
While women make up slightly more than half of the US workforce and half of the college-educated workforce, they are underrepresented in the nation's science, technology, engineering, and mathematics, or STEM, jobs. To encourage more women to consider STEM careers, DOE built a webpage with articles about women who work in STEM areas for the Department, including the national labs. Several outstanding scientists from PNNL are featured, including Karin Rodland, Ruby Leung, Julia Laskin, Meredydd Evans, Alla Zelenyuk, and Kerstin Kleese van Dam.
To take advantage of enormous resources that next-generation super computers are expected to have, DOE researchers at PNNL designed a new put_notify capability that allows a process to initiate and complete data to another process without synchronization.
Congratulations to Dr. Daniel Chavarría, a computer scientist at the U.S. Department of Energy's Pacific Northwest National Laboratory, on being selected to present at the 13th Institute of Electrical and Electronics Engineers (IEEE) and Association for Computing Machinery (ACM) International Symposium on Cluster, Cloud and Grid Computing. The conference has only a 22 percent acceptance rate, and Chavarría's paper was one of only 57 papers accepted.
