Speculative Multithreaded Processors
Architects of future generation processors will have hundreds of millions of transistors with which to build computing chips. At the same time, it is becoming clear that naive scaling of conventional (superscalar) designs will increase complexity and cost while not meeting performance goals. Consequently, many computer architects are advocating a shift in focus from high-performance to high-thr...
متن کاملSpeculative multithreaded Processors - Computer
S emiconductor technologies—along with innovative computer architectures—have provided the bricks and mortar for building phenomenal improvements in processing speed during the past decade, culminating ultimately in the hundreds of millions of transistors used to build increasingly fast on-chip devices. Innovations in computer microarchitecture and accompanying compilers have enabled us to make...
متن کاملDynamic Thread Resizing for Speculative Multithreaded Processors
There is a growing interest in the use of speculative multithreading to speed up the execution of a program. In speculative multithreading model, threads are extracted from a sequential program and are speculatively executed in parallel, without violating sequential program semantics. In order to get the best performance from this model, a highly accurate thread selection scheme is needed in or...
متن کاملSupporting Speculative Multithreading on Simultaneous Multithreaded Processors
Speculative multithreading is a technique that has been used to improve single thread performance. Speculative multithreading architectures for Chip multiprocessors (CMPs) have been extensively studied. But there have been relatively few studies on the design of speculative multithreading for simultaneous multithreading (SMT) processors. The current SMT based designs IMT [9] and DMT [2] use loa...
متن کاملCriticality Driven Energy Aware Speculation for Speculative Multithreaded Processors
Unending quest for performance improvement coupled with the advancements in integrated circuit technology have led to the development of new architectural paradigm. Speculative multithreaded architecture (SpMT) philosophy relies on aggressive speculative execution for improved performance. However, aggressive speculative execution comes with a mixed flavor of improving performance, when success...
