ASSOC vs SHMMAP vs POINT_LUNs vs READ_BINARY? [message #68949]

I have a large multidimensional array. I want to sort it, without
doubling the memory requirement by making a same-size array and
copying data over, sections at a time.

I hear about:
- ASSOC? But the raw data is not in large consecutive chunks. Does
this preclude its use?
- SHMMAP? Seems very low-level and risky without experience.
- READU and lots of POINT_LUNs? Would this execute slowly?
- READ_BINARY with the TEMPLATE keyword? I should like to hard-code
the template rather than use the BINARY_TEMPLATE GUI. I suppose this
is possible?

I am guessing that READ_BINARY with TEMPLATE is the best option, to
read in the data in a sorted manner straight away, assuming I can
write my own template so no user interaction is required. Is this
right? Thanks in advance.
