title: i am trying to create a 925x902 grid at 0.005 precision and it is very time consuming, how can it be sped up?
body: <p>this is the main body code and is there any way of speeding it up as it takes almost all day to produce an output file</p>
  <pre><code>from landlab import RasterModelGrid
  
  
  mg=RasterModelGrid((925,902),0.005) 
  
  
  from landlab.io import read_esri_ascii
  (mg, z) = read_esri_ascii('dem46.txt', name=&quot;topographic__elevation&quot;)
  
  mg.set_closed_boundaries_at_grid_edges(True, False, True, False)
  
  from terrainbento import Clock, Basic
  clock = Clock(start=13800, stop=21300, step=1500)  
  #time step 25 mins from dem46 to dem71
  
  model = Basic(clock, mg)
  model.run_one_step(1500)
  mg.save('dem46.nc')
  </code></pre>
