On the efficacy of call graph-level thread-level speculation

With the current trend toward multicore architectures, improved execution performance can no longer be obtained via traditional single-thread instruction level parallelism (ILP), but, instead, via multithreaded execution.Generating thread-parallel ...

Chip multiprocessors with thread-level speculation have become the subject of intense research. This work refutes the claim that such a design is necessarily too energy inefficient. In addition, it proposes out-of-order task spawning to exploit more ...

To achieve high performance, contemporary computer systems rely on two forms of parallelism: instruction-level parallelism (ILP) and thread-level parallelism (TLP). Wide-issue super-scalar processors exploit ILP by executing multiple instructions from a ...
