Roll issue on Rocks-based GPU Cluster

Hi,

I am trying to build Rocks-based GPU Cluster.

  • No GPU on frontend

  • Using CUDA 5.0 & 5.1 (both tested for x86_64) Roll

  • Rocks version 5.4 (i386)

  • add CUDA roll (Successfully done)

  • Enable CUDA roll (Successfully done)

The problem comes on rebuilding the distribution:

  • No any CUDA roll is included in the list of rolls along with others.

What could be the possible reasons??? Any Idea please.
