Modeling and Analysis of Simultaneous Multithreading

Modeling and Analysis of Dual Block Multithreading

Instruction level multithreading is a technique for tolerating long– latency operations (e.g., cache misses) by switching the processor to another thread instead of waiting for the completion of a lengthy operation. In block multithreading, context switching occurs for each initiated long–latency operation. However, processor cycles during pipeline stalls as well as during context switching are...

Petri Net Analysis of Non-Redundant and Redundant Execution Schemes

The quest for high-performance has led to multiand many-core systems. To push the performance of a single core to the limit, simultaneous multithreading (SMT) is used. SMT enables to fetch different instructions from different threads, hiding latencies in other threads. SMT also gives the opportunity to execute redundant threads (redundant multithreading, RMT) and thus to detect faults by compa...

Chip Multiprocessors – A Cost-effective Alternative to Simultaneous Multithreading

In this paper we describe the principles of the chip multiprocessor architecture, overview design alternatives and present some example processors of this type. We discuss the results of several simulations where chip multiprocessor was compared to other advanced processor architectures including superscalars and simultaneous multithreading processors. Although simultaneous multithreading seems...

Simultaneous Multithreading: Maximizing On-Chip Parallelism - Computer Architecture, 1995. Proceedings., 22nd Annual International Symposium on

This paper examines simultaneous multithreading, a technique permitting several independent threads to issue instructions to a superscalar's multiple functional units in a single cycle. We present several models of simultaneous multithreading and compare them with altemative organizations: a wide superscalar, a fine-grain multithreaded processor, and single-chip, multiple-issue multiprocessing ...
