Before revision:  On a 60-core machine , we achieve 13.23 -38.99 x and 1.19 -13.76 x self-relative parallel speedup for k-clique counting and k-clique densest subgraph, respectively.
After revision:  On a 30-core machine with two-way hyper-threading, our algorithms achieve 13.23 -38.99 x and 1.19 -13.76 x self-relative parallel speedup for k-clique counting and k-clique densest subgraph, respectively.
