When adding Cuda to app_info.xml (running optimized applications) you need to declare a number of files, including libfftw3f-3-1-1a_upx.dll. Since there is already a Cuda specific FFT library (cufft.dll) I am wondering whether this file is still required.

I haven't tried it myself, but someone told me he is successfully running Cuda without this file.

libfftw3f-3-1-1a_upx.dll is required if you are running the stock (Berkeley) CUDA application, because that version has the ability to fall back to CPU processing if it comes across a problem with the CUDA card.

It's possible that some of Raistmer's applications no longer have this dependency, though I don't think he's done a combination version yet which uses full optimisation (and hence not doesn't need libfftw3f-3-1-1a_upx.dll) when CPU fallback is invoked.

Probably best to keep the reference in app_info.xml unless you're absolutely certain that the version you're using doesn't need it: it doesn't add a huge amount extra to the complexity.

Thanks Richard!

I'm working on a detailed instruction (in Dutch) on how to install and run optimized applications. My experience is that it's best to check all details to prepare for questions :-)
