Center for Accelerated Application Readiness (CAAR)

In preparation for next-generation supercomputer Summit, the Oak Ridge Leadership Computing Facility (OLCF) selected 13 partnership projects into its Center for Accelerated Application Readiness (CAAR) program. A collaborative effort of application development teams and staff from the OLCF Scientific Computing group, CAAR is focused on redesigning, porting, and optimizing application codes for Summit’s hybrid CPU–GPU architecture. Through CAAR, codes teams gain access to early software development systems, leadership computing resources, and technical support from the IBM/NVIDIA Center of Excellence at Oak Ridge National Laboratory. The program culminates with each team’s scientific grand-challenge demonstration on Summit. The modeling and simulation applications selected for the CAAR program include:
