    • assign

      public List<SuiteBalancer.Assignment> assign(Collection<String> suiteNames, int slaves, long seed)
      Assign based on execution time history. The algorithm is a greedy heuristic assigning the longest remaining test to the slave with the shortest-completion time so far. This is not optimal but fast and provides a decent average assignment.
