Known issue: "There is a known issue that the compile time for CUDPP is very
long and the compiled library file size is very large. On some systems with <
4GB of available memory (or virtual memory), the CUDA compiler can run out of
memory and compilation can fail. We will be working on these issues for future
releases."
How much memory do you have on your system?

My system has 4GB RAM, however 1GB is reserved as video RAM. I have 4GB of
virtual memory
To be exact: 3061 MB accessible physical memory and 4095MB virtual memory

So it sounds like that is precisely on point for the aforementioned
release-note known-issue, I'm afraid. This is an NVIDIA compiler issue rather
than a CUDPP issue, with the proviso (of course) that it's CUDPP code that is
making the compiler use so much memory. Can you up your virtual memory (4 GB
sounds low for a modern system anyway) and see if that might allow the compiler
to finish?

I have upped the virtual memory to 8 GB (4GB on each of my drives, the maximum
allowed by Win7 x32). It does not resolve the 'out of heap space' bug

You might need to upgrade to a 64-bit OS. I'm not sure we have tested CUDPP
2.0 on a 32-bit OS...

unfortunately CUDPP 2.0 seems to require a 64-bit OS to compile successfully
currently.

We would be delighted to hear any suggestions you had about how to structure
the project such that it eliminates this issue. If this was easily fixable, I
assure you we would place high priority on getting it fixed.
