TITLE:  Multiprocessor Architectures for Speculative Multithreading                                                                                     

ABSTRACT:  One of the biggest challenges facing computer architecture today is the design of parallel architectures that make it easy for programmers to write parallel codes. One of the architectural technologies that is showing great versatility and potential in this direction is Speculative Multithreading.  In this talk, I will discuss the many uses of this technology in multiprocessors, and its remarkable potential for performance and programmability (Thread-Level Speculation, Speculative Synchronization, Transactional Memory, and BulkSC), hardware reliability (Paceline), and software dependability (ReEnact and Iwatcher).
