> To use GPUs in distributed mode, we need to make it so that 
> 1. GPU instructions are called as part of the higher order functions invoked on the RDDs
> 2. They are shipped as part of the body of a parfor
> This JIRA explores, implements & solidifies option 2.
> Option 2 has an intuitive advantage over option 1. 
> If operations in a parfor body are implemented on the GPU, the hope is that the data
will stay on the GPU longer instead of ping-ponging between the host and the device memories.
> We can later explore if and option 1 needs to be implemented.
