----------------------------------------
Fix Version/s: (was: SystemML 1.0)
SystemML 1.1
> Explore the use of GPU instructions in a Parfor body (for Spark)
> ----------------------------------------------------------------
>
> Key: SYSTEMML-1405
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1405
> Project: SystemML
> Issue Type: Sub-task
> Components: Runtime
> Reporter: Nakul Jindal
> Fix For: SystemML 1.1
>
>
> 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.
