Vertica came out of the C-Store paper (https://web.archive.org/web/20100619191833/http://db.lcs.mit.edu/projects/cstore/vldb.pdf https://web.archive.org/web/20100619191833/http://db.lcs.mit...). The C-Store paper pre-dates ParAccel being incorporated. Many of the C-Store authors were involved in Vertica's creation. If you want to be technical, C-Store was the real innovator...and those people refined and commercialized it as Vertica.
