Hi,

Are there any good examples or guides about making best use of multiple cores, i.e. which nodes are able to parallelize code execution, how to design workflows with this in mind, and how best to use the "Parallel Execution Nodes"?

Will introduction of scripting nodes (R,Python) into such workflows introduce "uni-core bottlenecks"?

Cheers,

Steve.
