FollowNERSC Hosts Application Readiness and Portability Meeting with OLCF and ALCF
September 25, 2014
Over 30 staff members from NERSC, Oak Ridge Leadership Computing Facility and Argonne Leadership Computing Facility met at Berkeley Lab’s Oakland Scientific Facility September 24-25 to coordinate strategies for application readiness in preparation for the next generation of supercomputers. The meeting also included representatives from Sandia, Los Alamos and Lawrence Livermore National Laboratories.
During the meeting, each Office of Science computing facility presented an overview of its expected supercomputing architecture and programming model. An open discussion and brainstorming session on application portability and performance portability across architectures followed. Attendees also discussed how to provide users access to each other’s systems so they can test performance portability. The attendees have committed to sharing best practices for application readiness and user training.
Similar to NERSC’s Exascale Science Applications Program (NESAP), each of the leadership computing facilities will launch its own application readiness efforts aimed at preparing application codes for next generation systems.
“Many of the same applications and users run at NERSC, OLCF and ALCF, so it is important to coordinate our application readiness efforts,” said Katie Antypas, NERSC’s Services Department Head.
The NESAP effort is designed to support NERSC’s next-generation supercomputer, Cori, a Cray XC system slated to be deployed in 2016. NESAP features partnerships with 20 application code teams and technical support from NERSC, Cray and Intel. Through NESAP, researchers will work with NERSC and vendor staff to optimize application codes for Cori's Knights Landing manycore architecture.
