nvidia-331 recommends nvidia-prime, which is needed in order to get
hybrid graphics to work.
This said, I've just found out that simply rebuilding hwloc generates a
libhwloc-plugins package with the correct dependencies:
Depends: libc6 (>= 2.4), libltdl7 (>= 2.4.2), libopencl-1.1-1,
libpciaccess0, libxml2 (>= 2.7.4), ocl-icd-libopencl1 (>= 1.0) |
libopencl1, libhwloc5
This will make sure that libhwloc-plugins does the right thing by
pulling in ocl-icd-libopencl1.

Title:
apt-get install nvidia-331 triggers 691 packages to be installed
Status in hwloc package in Ubuntu:
In Progress
Status in nvidia-graphics-drivers-331 package in Ubuntu:
Invalid
Bug description:
There appears to be a package dependency cascade that occurred approx
12 hours ago. Attempting to install libboost-all-dev causes this: "0
upgraded, 791 newly installed, 0 to remove and 3 not upgraded."
The 791 packages include much of the gnome and kde desktops, a web
browser, some chat clients, all of X11 .. which is crazy for a package
needed to compile C++ programs for a server.
I traced the dependencies: its a rather long, boring chain ... it
depends on stuff which depends on libboost-mpi1.54.0 which causes
694 packages to be installed
Tracing through eventually leads to libhwloc5 which seems like it
should be harmless .. but that leads to libopencl1 which is a
virtual package. If you recall, opencl is a GPU general-purpose-
computing thing, so, unsurprisingly, we see a dependence on nvidia:
Package libopencl1 is a virtual package provided by:
nvidia-libopencl1-331-updates 331.113-0ubuntu0.0.4
nvidia-libopencl1-331 331.113-0ubuntu0.0.4
nvidia-libopencl1-304-updates 304.125-0ubuntu0.0.1
nvidia-libopencl1-304 304.125-0ubuntu0.0.1
ocl-icd-libopencl1 2.1.3-4
Next: apt-get install nvidia-libopencl1-331-updates results in: 0
upgraded, 681 newly installed, 0 to remove and 3 not upgraded.
Tracing through that, we get to nvidia-331-updates which requires
nvidia-prime which causes this:
0 upgraded, 696 newly installed, 0 to remove and 3 not upgraded.
This is on a server that doesn't have a graphics card ..
It appears that nvidia-prime is the prime suspect, here: somehow,
libhwloc5 , through libopencl, requies nvidia drivers to be
installed, but the nvidia drivers require a package that cause the
gnome+kde desktops to be installed ...
