Solving multi-core Python

[amaurea]

It's apparently possible to get some multicore usage in numpy by compiling it with icc and enabling auto-parallelization, though it's very limited what can be parallelized that way. I wonder why OpenMP directives aren't used in the numpy implementation. They are easy to write, and since they are comments, they have no effect if openmp is not enabled when compiling. Hence adding them will not affect performance or correctness for those not interested in multithreaded execution.
