NVidia hardware is GPU-based math hardware, the chips in high-end 3d graphics
cards. Cuda is the name of the NVidia development environment. Your Hadoop job
want to run code on an NVidia card.
I'm guessing 'jcuda' is a utility program for the CUDA tools. What is your code
written in?

Thanx Harsh, I am not so much expert in Linux but knows little bit.
Do I have to research on my Application *nvidiactl* level or there or
just simple commands to make Hadoop uses /dev/nvidiaactl ( driver file
libcuddpp.so )
Best Regards, Adarsh

Greetings to all,
Today i came across a strange problem about non-root users in Linux (
CentOS ).
I am able to compile & run a Java Program through below commands properly :
[root@cuda1 hadoop-0.20.2]# javac EnumDevices.java
[root@cuda1 hadoop-0.20.2]# java EnumDevices
Total number of devices
