DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. NERSC is currently hiring eight post-docs to assist this effort. The NESAP program at NERSC addresses the software issues that will arise as scientists adapt their applications to take advantage of exascale hardare. The NERSC Cori supercomputer – an Intel Knights Landing based system – is a major stepping stone on the Exascale roadmap. Through NESAP, NERSC will partner with approximately 20 application teams to help prepare codes for the Cori architecture. Announcements are expected this month (August 2014) naming the successful applicants. We expect some very interesting papers to come out of this project. A key news item in the NERSC announcement is the expected delivery of KNL hardware in late 2015 along with the NERSC opening for eight post-docs. These early-career scientists will be assigned to science application teams to help research optimization strategies and help propel large NERSC applications toward exascale.
The NESAP teams will seek to meet the exascale challenges through broad-based user training, access to early development systems and application kernel deep dives with Cray and Intel specialists. In addition, NERSC and Cray have established a joint Center of Excellence to help users port and optimize target applications that will run on Cori. Application teams in NESAP will have access to the following:
- A partner from NERSC’s Application Readiness team who will assist with code profiling and optimization
- Access to Cray and Intel resources to help with code optimization.
- Up to 1M MPP hours in 2014 and 2M MPP hours in 2015 for code testing, optimization, scaling and debugging on Edison
- Early access to prototype Knights Landing processor hardware (expected in late 2015)
- Early access and significant hours on the full Cori system (expected delivery mid-2016)
- Opportunity for a Post-doctoral researcher to be placed within your application team. (NERSC will fund 8 Post-doctoral researchers and place each one within one of the 20 NESAP teams meaning that approximately 40% of NESAP applications teams will include a NERSC sponsored Post-doc.)
