+That will initialize load balancer `slb`  with range from lower bound (`1`) to upper bound (`100`) and with min (`2`) and max (`4`) chunk sizes which are optional which will work on communicator `mpi_comm`.
 Simpler initialization is also possible with default min and max chuck sizes:
 ```cpp
-StaticLoadBalancer slb(MPI_COMM_WORLD, 1, 100);
+StaticLoadBalancer slb(mpi_comm, 1, 100);
 ```
 This is a barrier for the whole communicator.

 ```cpp
 std::string rlbtype = std::string("dynamic");
-RuntimeLoadBalancer rlb(rlbtype, MPI_COMM_WORLD, 1, 100, 2, 4);
