Ryan Abernathey was intend to compare the speed difference between using cluster or not using it. It should speed up when use cluster as said by Ryan in that notebook. But result is not. So, why?
Could you be more precise on the cell you’re comparing in the notebook?
If you’re talking about %time ds.THETA.isel(k=0).mean(dim='time').load(), then this is probably because the selected data is so small that using a Dask Gateway cluster just add some overhead.
Yes. I was talking about the %time ds.THETA.isel(k=0).mean(dim='time').load().
When calculate the mean sst in cell 9 and 10 not using the cluster, the time is about 15s. And in cell 13 using the cluster, the time is about 17s.
I also tried some other calculation (Yes. Small data set as you mentioned). The result shows that the cluster dose not speed up the calculation.
