### AMD App SDK 2.4

Just FYI, but the new AMD App SDK 2.4 switches environment variables (ATISTREAMSDKROOT -> AMDAPPSDKROOT, ATISTREAMSDKSAMPLESROOT -> AMDAPPSDKSAMPLESROOT)

The automatic download site also has changed, along with a few other things:

1. Windows XP support is no longer in a separate installer. There's only two installers now (one for 64 bit, one for 32 bit)

Here's the diff for getdeps.bat (note: these diffs happen to include the changes I made with my other topic on updating the windows build system which moved from modifying the registry to generating visual studio property sheets).

getdeps_diff.txt

Both 32 and 64 bit releases are building right now (fingers crossed to see if it works )

edit:

hmm, something's wrong with the 32 bit build... hold on a sec

edit2:

I'm not sure why, but there appears to be a conflict between the cl/cl.hpp in $(LUX_WINDOWS_BUILD_ROOT)/include and$(AMDAPPSDKROOT)include. Removing the file fixes the problem, but I'm not sure what effect this will have on building with CUDA.

edit3:

Just took the fresh builds for a test drive, it seems that the new SDK is significantly faster. I remember getting GPU loads of ~30-35% before, now I'm getting loads of ~50%. S/s and C/s have also gone up significantly, though I can't provide a concrete performance improvement.
