> I'm stuck at setting the correct CUDA environment... Is there anyone
outdated information. I also cannot answer any questions about it. But
> Dear all,
>
> I'ml currently trying to develop a 3D GPU based segmentation plugin for
> ImageJ. I learned Cuda programming on this wonderful website :
>
>
https://www.udacity.com/course/cs344>
> And I usually develop in Java by using the IDE Netbeans.
>
> I first wrote my ImageJ plugin without GPU computing. I see my method is
> working, but very slow as expected. I need to speed up the process using
> GPUs. And I'm stuck at setting the correct CUDA environment...
> Is there anyone that can help me ?
>
> - I have Windows 7 64 bits,
> - I installed the last Cuda toolkit v6.5
> - and the binaries for windows x64 of JCuda
>
http://www.jcuda.org/downloads/downloads.html> - I can provide more informations if necessary...
>
> At this point I have to admit I'm lost and desperate - I setup a lot of
> environment variables so that some dll can be linked correctly - I copied
> and paste the jar and dll of JCuda a bit everywhere in the folders so that
> Java could find it at least in one place... I know that something happened
> since the error when I tried to compile "Simple_JCuda_Plugin.java" has
> changed. But know I'm stuck, having desesperately the same error (listed at
> the end of this email).
>
> Is there anyone who can help me or who knows a more simple way of
> developping using Cuda (maven ? / Change OS ? ).
>
> Some help would be very much appreciated...
>
> Thanks
