Indeed, the change was merged yesterday. If you grab the latest master, the computation parallelism can be set by the parameter compiler.parallelism: -- 0, the default, means to use the storage parallelism as computation parallelism -- negative value, means to use all available cores in the cluster -- positive value, means to that number of cores, but it will fall to back to use all available cores if the number is too large.
