2004-07: MOLAR – Modular Linux and Adaptive Runtime Support for High-End Computing
This project was a multi-institution research effort that concentrated on adaptive, reliable, and efficient operating and runtime system solutions for ultra-scale high-end scientific computing on the next generation of supercomputers. It addressed the challenges outlined by the U.S. Department of Energy (DOE) Forum to Address Scalable Technology for Runtime and Operating Systems (FAST-OS) and the U.S. National Coordination Office for Networking and Information Technology Research and Development (NCO/NITRD) High-End Computing Revitalization Task Force (HECRTF) activities by providing an adaptable runtime support for high-end computing operating and runtime systems. This research primarily concentrated on advancing computer reliability, availability and serviceability (RAS) management systems to run large and long-running applications efficiently on future ultra-scale computers, and on providing advanced monitoring and adaptation mechanisms for improved application performance and predictability.
