assigning memory on windows os crashing labview app

[k-waris]

Hi

I must be doing something really stupid and very easily crashing my pc by writing only few functions in labview!

I want to pre-allocate memory of 5GB at the start of application. So I used simple initialize function to create 2d array of NaN dB points as shown in the image.  I have 8GB of memory but the error popped up as shown in screen. And I only tried 1GB as shown in image. Could I not have this pre-allocation?

Are you running LabVIEW 32-bit? You can't allocate that much memory with a 32-bit operating system or in LabVIEW 32-bit.

Guaranted 64 bit os and Labview!

What happens if you wire the equivalent number directly instead of computing it?

Hi k-waris,

Well, we cannot see which value you used for channel count.

But still then you want to create a 2D array of (atleast) 1G*1 of DBL, which needs 8GB of memory.

With any OS and other software running I guess it will be hard to have 8GB continuous RAM available!
