6. Perform Dask Calculation

In this section you will perform a Dask calculation, observing the cluster behaviour via the Dask dashboard.

Starting point: you should be logged in to DataLabs, with a notebook client and a Dask dashboard.

Copy and paste the following text into the next cell:

import dask.array as da
a = da.random.normal(size=(10000, 10000), chunks=(500, 500))
a.mean().compute()

Running this cell will perform the Dask calculation. While the calculation is being performed, you can observe the scheduler co-ordinating the work on the Dask Graph.

Back on the notebook tab, the Dask calculation will be outputted.
