Sir We are doing project in CUDA + HADOOP. We are able to compile the HADOOP + CUDA code and the jar file is created. The problem is that we are not able to execute the code. The CUDA code which is a part of the above program can be compiiled and executed successfully. But if we copy the same CUDA code into the Hadoop code we are getting the followng error:
Error while loading native library “JCublas-linux-x86” with base name “JCublas”
