Input Parameter

da - the distributed array

Output Parameters

dim - dimension of the distributed array (1, 2, or 3)
M - global dimension in first direction of the array
N - global dimension in second direction of the array
P - global dimension in third direction of the array
m - corresponding number of procs in first dimension
n - corresponding number of procs in second dimension
p - corresponding number of procs in third dimension
dof - number of degrees of freedom per node
s - stencil width
bx - type of ghost nodes at boundary in first dimension
by - type of ghost nodes at boundary in second dimension
bz - type of ghost nodes at boundary in third dimension
st - stencil type, either DMDA_STENCIL_STAR or DMDA_STENCIL_BOX

Note

Use NULL (NULL_INTEGER in Fortran) in place of any output parameter that is not of interest.
