In NVIDIA GPU direct section:
It appears to me that GPU Direct 2.0 include GPU Direct 1.0 features ( it said “adds support” ).
Is this true ?
If yes, How could I test my MPI to see whether the feature of GPU Direct 1.0 is there ? I couldn’t figure out anything from the example code i.e mpi_pinned.c in the package.
If no, Is it possible to install the driver in the website together with CUDA 4.0 driver? Because the file name “nvidia-gpudirect-3.2-1.tar.gz” suggests driver 3.2.
