Greetings,
I have an ASUS N56V laptop with a GeForce GT 650 M, running Fedora 17
64-bit. The proprietary NVIDIA drivers failed to install so I followed the
instructions from the following page to set up nouveau and bumblebee in
order to install CUDA 4.2.

The CUDA tests run successfully. However, when I try to run the ApoA1
benchmark within the latest NAMD nightly build directory, I get the
following error:
$ export LD_LIBRARY_PATH=`pwd` && ./namd2 +idlepoll apoa1.namd

Aborted (core dumped)
Is it because I don't have the proprietary NVIDIA drivers installed, or
because I have Cuda 4.2 instead of 4.0? Then why can I run successfully
other programs with the GPU, including GROMACS?
Thanks in advance.
Thomas
