I have real huge sets of data originating from an image-like (many "pixels") data aquisition that is interpreted according to a similar large set of objects with many properties. This is all fed also through different GUI windows. Before I had this fed into and out of the sub vis via ontrols/indicators as learned. Now I just finished converting into keeping the master set of data in gobal variables and creating a local copy at the entry of the sub VI. Background of this not so common approach is, that once a front panel was open ( as in a user interface happens eventually) the data in the controls/indicators is still using up memory, Whereas since LV 7, I can release local memory like copies of global variables on exit.
Of course in a man/machine interface speed is not so essential and timing performance may require a different approach, but my problem was reaching the all terminating limit of 2GB / process. Linux 64 with lots of RAM might have helped otherwise ;-) Gabi
