Parallelizable vs. Parallelable

Question

Which sentence is correct and meaningful?

1. The following computer algorithm is highly parallelizable.

2. The following computer algorithm is highly parallelable.

Answer 1

An article in Wikipedia uses various derivatives of "parallelize":

parallelizable
parallelizability
parallelization
parallelizable

so it looks like that's the customary term.

Wikipedia "Parallel algorithm"

I have seen "parallelable" used in reference to electronic inverters, meaning they can be connected in parallel for higher power output, so it's a valid word, but maybe in other contexts.

Answer 2

According to this Google Ngram It seems like parallelizable is far more common, so I believe parallelizable should be preferred over parallelable.
