Hi, I'm working on hadoop 2.2.0 and I'm writting a C++ application with pipes. I would like to use also CUDA in my mapper/reducer but I'm not able to find enough info. I'have found this interesting slide: http://www.slideshare.net/airbots/cuda-29330283 and this page in the wiki http://wiki.apache.org/hadoop/CUDA%20On%20Hadoop.
I don't understand where are these functions: - void processHadoopData(string& input); - void cudaCompute(std::map<string,string>& output); I don't understand where I have to write the code and if it is really possible. Is there any tutorial to learning how to configure hadoop+cuda, write the code, compile it, execute it? Is there any example?
