Does anyone know if labview can be made large address aware??

If labview is not large address aware, I think you can make it that way by using editbin.exe if you have C/C++ build tools. This option modifies something inside the exe file. But I don't have the tools to try it.

Another hack that may allow you to use more than 2GBytes of RAM is to use HDF5 as a memory buffer.  This will be slower than normal memory access (by a large margin), but will be much faster than using a disk buffer.  I have successfully used HDF5 as a RAM buffer, but have never had a machine with more than 2GBytes of RAM, so never pursued that angle.  There is a simple (and out of date) HDF5 toolkit available as sfpFile.  You will have to modify it to include a different file access model to pull this off.  Check the HDF5 website and user documentation for details.

I've written a LabVIEW wrapper for HDF5 1.8 alpha should somebody be interested in testing. It really is more up-to-date than the NI version and to my experience HDF5 1.8 is stable although it still is on alpha stage. The HDF group is planning to release final version HDF5 1.8 later this year. Note that the wrapper is really only for advanced users so novice users don't bother.

Thanks Tomi.  I was hoping you would chime in.  I also looked and found that HDF5 has not been tested on Vista64.  It should be no more than a compile away from full support, since the root code supports up to 128-bit pointers (for those of you with really big data storage needs).  However, the HDF5 team has their hands full trying to get 1.8.0 out the door, so it may be up to someone else to try this.

DF, you are right, I've not recompiled my HDF5 code for Vista. I guess I won't have time to do this in the near future. I'm hands full of work.
