for cs : http://csrankings.org/ (this is mainly for potential phd students as a reference, and this ranking seems only fair for certain fields, some conferences are not included. If you are interested in certain fields of study and the major conference was not indexed in it, you should ignore this ranking)
http://cs.brown.edu/~sk/Memos/Grad-School-Recos/
