Announcing the LabVIEW 64-bit Pioneer Beta

[AdamKemp]

Blue screens are usually caused by driver issues. You should try to figure out which driver caused the blue screen and see if there are updates available. I don't think this has anything to do with 32-bit versus 64-bit LabVIEW. You should have no trouble using 32-bit LabVIEW on Vista 64.

Can anyone tell me whether LabVIEW for 64-bit will run on Windows XP x64?  Please do not ask me why I am not running Vista x64 . . . 

Also, will this version of LabVIEW run on either a 32-bit or a 64-bit machine?  Meaning, will I have to keep several versions around, or bundle executables everytime I want to port from a 64-bit programming PCto a 32-bit operating PC?

Classic LabVIEW will run on 32bit and 64bit OS, so if you only want to use one version, you have no need for 64bit LabVIEW. Simply continue to use the 32 bit version. The only significant advantage of a potential 64bit LabVIEW version is the much larger address space, useful if you have extremely large data structures.

 You might have noticed that this thread started well over a year ago and that particular beta has probably ended long ago.

Historically, new LabVIEW versions have been released around NI week. Since everybody involved in the beta is under NDA, you would need to wait for an official word from NI before these things can be discussed in public.

"32-bit LabVIEW running on 64-bit Vista or 64-bit Windows 7 can use up to 4 GB of address space"

How much can 64 bit labview use on Windows 7 x64 ?

How much RAM do you have?

Technically the address space available to a 64-bit processor is 16 exabytes. Practically speaking, though, most processors don't actually use all 64 bits because no one actually has nearly that much memory available. In my testing I found that the only limitation to how much memory you could use was how much RAM you had available. Once you start actively using as much memory as your physical RAM Windows would slow to a halt due to excessive paging. I have successfully worked with arrays as big as 8 gigabytes (copied once that would consume my entire 16GB of RAM, so I had to be very careful). That's one array in 64-bit LabVIEW using twice as much memory as 32-bit LabVIEW was able to use as a whole.

Thanks Adam, I was just wondering if LabVIEW itself was limited before the OS, we do use large arrays, e.g when processing e.g. when processing INL of a high resoultion converter, (e.g. a histogram of codes = 2^24 bits wide....troublesome under 2G/3G OS limitation)
