v1 v2 5 5 Subdivide into the 32 layers. Each of the 32 layers has an equal amount of data in each layer (so, the thickness of the layers will vary, in order to increase/decrease the amount of data. 6 6 7 [[Image(Kens1.png, 600px)]] 7 8 8 9 … … 11 12 There are 8 DXlayer machines, each dxlayer machine gets 4 of the layers. 12 13 14 [[Image(kens3.png, 600px)]] 15 16 13 17 == Step 3 == 14 18 15 19 For each set of 4 layers, called dxlayer[num], subdivide those to have segments of equal amount of data. This example here only has 8 segments per dxlayer[num]. Also, note that everything is divided in integer units of ra/dec (no fractional degrees) 16 20 21 [[Image(kens2.png, 600px)]] 22 23 17 24 == Step 4 == 18 25 19 26 Each of these segments corresponds to a datastore. Each datastore is of the same size, and roughly maps to 1 dxlayer machine. 27 28 [[Image(Kens4.png, 600px)]] 29 20 30 21 31 == Final Construction ==
