property ctypes_value

Returns

first value in correct type.

halo_aware

How to handle writes to this dat in a reduction sense. In general for a reduction in a pair loop a write will occur once per pair In the case where one of the pair is in a halo, the write will occur if the ithparticle is not in the halo?

property max

Returns

The maximum value in the array.

property mean

Returns

The mean value in the array.

property min
