[tlug] CUDA: Getting started

[Kalin KOZHUHAROV <me.kalin@example.com>]

Last Saturday's meeting there was some discussion about CUDA on linux...


It is fairly easy to start using CUDA on Gentoo:
$ emerge nvidia-{drivers,cuda-sdk,cuda-toolkit}

But check if your nvidia card has CUDA capability first:
http://en.wikipedia.org/wiki/CUDA#Supported_GPUs


Test that it works:
$ /opt/cuda/sdk/bin/linux/release/deviceQuery
/opt/cuda/sdk/bin/linux/release/deviceQuery Starting...

 CUDA Device Query (Runtime API) version (CUDART static linking)

Detected 1 CUDA Capable device(s)

Device 0: "GeForce GT 640"
  CUDA Driver Version / Runtime Version          5.0 / 5.0
  CUDA Capability Major/Minor version number:    3.0
  Total amount of global memory:                 2047 MBytes (2146762752 bytes)
  ( 2) Multiprocessors x (192) CUDA Cores/MP:    384 CUDA Cores
  GPU Clock rate:                                902 MHz (0.90 GHz)
....

Get something to run, e.g. this "Hello world" :
http://computer-graphics.se/hello-world-for-cuda.html

Compile it with `nvcc hello.cu` and run it with `./a.out`

Also check the examples in /opt/cuda/sdk/?_*
