Modeling and Analysis of Simultaneous Multithreading
نویسنده
چکیده
In simultaneous multithreading, several threads can issue instructions in each processor cycle. A simple and versatile timed Petri net model of simultaneous multithreading is proposed and is used to compare the performance of architectures with and without simultaneous multithreading. Performance results are obtained by event-driven simulation of net models and are verified by state–space–based analysis using combinations of modeling parameters for which the state space remains reasonably small.

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...
متن کاملPetri 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...
متن کاملChip 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...

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 ...
