Can a single query be split up into parts and run on separate processors
at the same time? No.

Can multiple incoming queries be run on different processors for better
performance? Yes.

Has someone been working on the problem of splitting a query into pieces
and running it on multiple CPUs / multiple machines? Yes. Bizgress has
done that.

choose an index scan if your joining column's datatypes do not
match
