ABSTRACT:
Recently, there appear to be a consensus from all chip vendors that microprocessor chipwill be dominated by multi/mani-core technology in a few years! In this talk, we discuss the challenges as well as opportunities facing architecture and software technology.
This talk will be based on both our own experience on working with fine-grain multithreading inspired by early data-driven execution/architecture/software models, as well as our recent experience gained in system software design and validation for the IBM Cyclops-64 supercomputer architecture with a mani-core chip technology integrating 160 cores on chip! We discuss several fundamental performance issues facing architecture and system software designers while mapping OpenMP programs onto such architectures.
