SPECfp and autopar
Continuing the SPECcpu theme, an interesting paper from Intel describing the performance upticks from autopar, SSE and other optimizations can be found here. On a dual-core they show decent gains on 6 benchmarks and slight gains on a further two.
Similarly, using the Sun Studio compiler, 8 benchmarks benefit from autopar, delivering a 16% improvement in the geometric mean on a dual-core processor (as illustrated here).
