Parallelism in Python

Question

What are the options for achieving parallelism in Python? I want to perform a bunch of CPU bound calculations over some very large rasters, and would like to parallelise th

Answer 1

Depending on how much data you need to process and how many CPUs/machines you intend to use, it is in some cases better to write a part of it in C (or Java/C# if you want to use jython/IronPython)

The speedup you can get from that might do more for your performance than running things in parallel on 8 CPUs.
