> Did someone have a look at what blaze [1] does? They seem to be pretty advanced regarding parallelism -- they also parallelize "simple" things like vector addition, which if we trust their benchmarks [2] seems to be beneficial starting at something like 50000 doubles
You should not trust benchmarks, especially where they have been done by people who wrote the software :-)
For Blaze, for things such as vector addition, they also use streaming stores to speed up the process.
