• Sun GridEngine backend. Specifying -Dbackend.backend=sge will use qsub to launch jobs. See also the filesystem assumptions for using the GridEngine backend.

• Support for scatter blocks, for example:

  task add_one {
    Int n
    command {
      python -c "print(${n}+1)"
    }
    output {
      Int incremented = read_int(stdout())
    }
  }
  
  workflow test {
    Array[Int] list = [1,2,3,4]
    scatter (x in list) {
      call add_one {input: n=x}
    }
  }
  

• Localization strategies for SGE/local backends. Instead of copying all files, one can specify hard-link, soft-link, and copy. By default they are tried in the order that they're listed here until one succeeds, though the priority is configurable. See filesystem assumptions for more information.
