You are running a simulation with only one block.

The short parfile from the U.G. does not include refinement variables,
so FLASH sees no reason to create any blocks beyond the initial root 
block.

Most likely the FLASH timers got comfused because you run with one block 
on 4 procs, so some procs are "running empty".

Again, I recommend starting with flash.par from the Sedov simulation 
directory. It has refine_var_1 and refine_var_2.
