CUDA Toolkit 3.0 released gentoo Portage ebuild linux installation kits

The linux gentoo portage installation has CUDA 3.0 kits.
It is currently “masked” but seems ok so far.

I have been running CUDA 2.3 and went through the following steps to upgrade to 3.0
(doubtless there are other ways too)
emerge --sync
ebuild /usr/portage/x11-drivers/nvidia-drivers/nvidia-drivers-195.36.15.ebuild fetch
ebuild /usr/portage/x11-drivers/nvidia-drivers/nvidia-drivers-195.36.15.ebuild merge
ebuild /usr/portage/dev-util/nvidia-cuda-toolkit/nvidia-cuda-toolkit-3.0.ebuild fetch
ebuild /usr/portage/dev-util/nvidia-cuda-toolkit/nvidia-cuda-toolkit-3.0.ebuild merge
ebuild /usr/portage/dev-util/nvidia-cuda-sdk/nvidia-cuda-sdk-3.0.ebuild fetch
ebuild /usr/portage/dev-util/nvidia-cuda-sdk/nvidia-cuda-sdk-3.0.ebuild merge

modprobe -r nvidia
eselect opengl set nvidia

/opt/cuda/lib/libcudart.so.2 had disappeared (the README suggests libcudrt is not really supported)
however I have rebuilt my executable with libcutil_i386.a instead. This is slightly slower on a GTX 295
which thinks it is two GPUs, so it may be the way I am doing threading on the host to use both GPUs
and does not affect others.

                        Thank you

I add that I’ve been using 3.0 on Gentoo since the beta in a production environment, works well.

Is there any reason for your rather complicated upgrade procedure with ebuild?
emerge -u nvidia-cuda-sdk
would do it.

“A Field Guide to Genetic Programming” is a great book.

Many thanks

Bill

Hmm I tried emerge -u nvidia-cuda-toolkit

today expecting to install 3.1 but panicked and aborted it

when emerge appeared to be loading CUDA 2.3.

I have installed CUDA 3.1 (nvidia-drivers-256.35)

using separate fetch and merge as for 3.0 above.
