I was trying to read ERA-Interim data, calculate anomalies using ds = ds - ds.mean(dim='longitude'), and similar operations along the time axis. Are such operations restricted to single cores?

Just multiplying two datasets (u*v) seems to be faster, though top shows two cores being used (I have 4 physical cores).

TIA, Joy
