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...

Hi Nicolas,

This looks like a JCuda issue, so you will probably have better luck asking in the JCuda forum: http://forum.byte-welt.net/byte-welt-projekte-projects/swogl-jcuda-jocl/?langid=2 You may be interested in this related effort to use OpenCL from ImageJ: http://developer.imagej.net/opencl But please note that that project is no longer maintained, and may contain outdated information. I also cannot answer any questions about it. But perhaps you will find it useful.
