Compute Unified Device Architecture

Some notes on legoing with CUDA on an ASUS EB1012 running Xubuntu 10.10 64-bit.

Installation is straightforward and well-documented in the Getting Start Guide. Download a bunch of code (Drivers/Toolkit/SDK) from CUDA 3.2 Downloads, run the installation, compile some stuff and you are ready to start legoing!

I highly recommend compiling/installing everything from scratch, it is by far the fastest path to a working environment! One lazy approach would be to skim the Getting Start Guide and following the copy-pastable notes below.

WARNING If you try to take a "shortcut" by re-using your systems currently installed driver or try installing a driver via some arbitrary PPA. Then you need to keep following in mind:

Installation

Required software:

sudo apt-get install vim lynx g++ ia32-libs libx11-dev libglut3-dev libgl1-mesa-dev libglu-dev libXmu-dev libxi-dev
