CUDA

Installation on Debian

There exist libcuda-dev packages in the non-free archive area, but they seem incomplete or obsolete (or both). I instead used the NVIDIA upstream files, installing CUDA onto a 64-bit Debian Unstable system 2010-01-25 (hand-rolled 2.6.32.6 kernel, built with gcc-4.4). This machine did not have CUDA-compatible hardware (it uses Intel 965).

• Download the Ubuntu 9.04 files from NVIDIA's "CUDA Zone".
• Run the toolkit installer (sh cudatoolkit_2.3_linux_64_ubuntu9.04.run)
  • For a user-mode install, supply $HOME/local or somesuch

* Please make sure your PATH includes /home/dank/local/cuda/bin
* Please make sure your LD_LIBRARY_PATH
*   for 32-bit Linux distributions includes /home/dank/local/cuda/lib
*   for 64-bit Linux distributions includes /home/dank/local/cuda/lib64
* OR
*   for 32-bit Linux distributions add /home/dank/local/cuda/lib
*   for 64-bit Linux distributions add /home/dank/local/cuda/lib64
* to /etc/ld.so.conf and run ldconfig as root

* Please read the release notes in /home/dank/local/cuda/doc/

* To uninstall CUDA, delete /home/dank/local/cuda
* Installation Complete

• Run the SDK installer (sh cudasdk_2.3_linux.run)
  • I just installed it to the same directory as the toolkit, which seems to work fine.

* Please make sure your PATH includes /home/dank/local/cuda/bin
* Please make sure your LD_LIBRARY_PATH includes /home/dank/local/cuda/lib

* To uninstall the NVIDIA GPU Computing SDK, please delete /home/dank/local/cuda
* Installation Complete

Building

SDK's common.mk

This assumes use of the SDK's common.mk, as recommended by the documentation.

• Add the library path to LD_LIBRARY_PATH, assuming CUDA's been installed to a non-standard directory.
• Set the CUDA_INSTALL_PATH and ROOTDIR (yeargh!) if outside the SDK.
• I keep the following in bin/cudasetup of my home directory. Source its output, ala eval `cudasetup`:

#!/bin/sh

CUDA=$HOME/local/cuda

[ -d "$CUDA" ] || { echo "$CUDA is not a directory, exiting" >&2 ; exit 1 ; }

echo "# run \"eval \`$0\`\" to source these exports"
echo "export CUDA_INSTALL_PATH=$CUDA"
echo "export ROOTDIR=$CUDA/C/common/"
# check for its current presence? FIXME
if [ -n "$LD_LIBRARY_PATH" ] ; then
	echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CUDA/lib64"
else
	echo "export LD_LIBRARY_PATH=$CUDA/lib64"
fi
