SPECfp and autopar
By sprack on Nov 11, 2008
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).
