edit: local[1] has been updated to local[N], thank you for the update!

Ok thanks, I didn't know that's what "local[1]" did, so the more relevant comparison would be with --master local[30]?

The algorithm took around 500 seconds to train on the NETFLIX dataset on a SINGLE processor, which is good for data as large as 1 billion ratings. - this is from the sequential portion of the test, the parallel portion is the next section.

Thanks for the update. The typo had me misinterpreting things. Now it makes more sense.

Assuming you're part of the team? Keep up the good work.
