how much RAM LabVIEW can handle ?

Hi Titou,

Regarding RAM Usage on RT, it's actually 2 GB.

Thanks for the link Evrem, I was expecting RT OS to e able to handle more memory... 
I guess there is not improvement to expect before LabVIEW goes 64bit... And I also guess there is still no official roadmap for a 64bit LabVIEW

LabVIEW 8.5 is "large address aware". This means it can directly address 4GBytes of RAM. It still has the 2G object limit and continguous array issues. Earlier versions of LabVIEW can only address 2GBytes of RAM.

All bets are off if you use an external DLL. For example, you should be able to use 4GBytes in LabVIEW 8.0 if you use an in-memory HDF5 file mode. I have not tried this, so cannot say for sure.

You are correct, there is no official roadmap for 64-bit LabVIEW...
