Allocation of 4G memory

[gabi_hor]

Hi

I am trying to allocate 4G of memory. I have WIN XP 64 bit with Labview 8.5. I add in the boot.ini the flag /PEA. I am using the attached procedure to allocate the memory in small (200M) batches. Nevertheless I can't allocate more then 2.4 G, Why?

Regards

Gabi

Hi Gabi,

have you cross-checked that LV8.5 is able to allocate this much memory (even on WinXP64)? 2.4GB is quite a lot of memory...

Edited:
I just found your old thread on the same topic It seems LV8.5 should be able to get this much memory...
Did you avoid any unneccessary data copies?

I think it is dependent on your RAM size.

How much RAM do you have?

Hi

I am looking at the Windows Task Manager. The Labview process allocates up to 2.4G, when I tried to allocate another batch of 200M, the program halt with the message "Not Enough memory". I ensure that no other process allocate a significant memory at this time.

Hello Gabi,

Have you seen this KnowledgeBase:

LabVIEW 8.5 is large address aware and should not have difficulty with 4GB of RAM.

Cheers!
