Exploring Thread-Level Speculation in Software: The Effects of Memory Access Tracking Granularity
Speculative execution is often the only way to overcome dataflow-imposed limitations and exploit parallelism when dependences can be discovered only at run-time. It also facilitates automatic parallelization of programs that exhibit complicated memory access patterns, which make complete compile-time dependence analysis either impossible or extremely complicated. A number of approaches for coar...
متن کاملSoftware and Hardware for Exploiting Speculative Parallelism with a Multiprocessor
Thread-level speculation (TLS) makes it possible to parallelize general purpose C programs. This paper proposes software and hardware mechanisms that support speculative thread-level execution on a single-chip multiprocessor. A detailed analysis of programs using the TLS execution model shows a bound on the performance of a TLS machine that is promising. In particular, TLS makes it feasible to ...

متن کاملA Chip-Multiprocessor Architecture with Speculative Multithreading
ÐMuch emphasis is now placed on chip-multiprocessor (CMP) architectures for exploiting thread-level parallelism in an application. In such architectures, speculation may be employed to execute applications that cannot be parallelized statically. In this paper, we present an efficient CMP architecture for speculative execution of sequential binaries without source recompilation. We present the s...
