hi there,
I have a scenario where I need to read the entire contents of a
multi-dimensional section'ed variable piecewise linearly.
for example, say the variable has shape [a][b][c] and I have section'ed
it as [s1][s2][s3]. say data type is double. now i need to read the
stream of elements, the total size of which is s1.size * s2.size *
s3.size in chunks, for example of chunk size x.
the API for variable doesn't allow me to specify "flat" linear indices,
so I need to calculate intermediate sub-sections, I guess. this looks
very complicated because the chunk size x might not be a simple multiple
of s3.size, s2.size*s3.size, etc.
So I can only think of two approaches: read "too" much data and then
throw away some. Read multiple times; perhaps this problem can be
formulated in maximally three read calls?
Has anyone solved this somehow? Or is there a trick in the API that I
haven't seen, to get a linear read command that preserves the offsets
and strides of sections?
thanks, .h.h.
