Memory management

[Barber Nichols]

I have a waveform file that is only 98 MBytes. When I try to use my labview program to analyze the data I end up with memory errors. I went through and Used the ShowBuffers tool and it is not showing that I am making lots of copies of my data but as soon as I open the data file the memory usage goes from ~100 MBytes to over 1 Gig. Is there something else I can do to reduce the memory usage.

Hello �

One overall suggestion to improve the memory usage is to avoid using local/global variables for data storage when possible. There are different ways of storing data that needs to be analyzed (File IO, for example).

Take a look at the following documents:
LabVIEW Performance and Memory Management
Managing Large Data Sets in LabVIEW

Hope this helps!
