Introduction

Carbon offers the 4.2 and 5.0 CUDA versions.

Components

There are three components to CUDA 4.2.

CUDA toolkit

• The CUDA toolkit contains the compiler nvcc, C include files, and libraries.
• Load this component as a module to compile and run applications that use GPUs on Carbon.

module load cuda

Driver

• This is a Linux kernel module (not to be confused with an environment module) plus supporting binaries and other files.
• This component is pre-installed on Carbon nodes that have a GPU.

SDK

• The GPU Computing SDK contains code samples and white papers to help you get started writing software with CUDA C/C++.
• Not necessary to merely run GPU applications.
• Available on Carbon in two forms.

• For inspection:

cd ~soft/cuda/NVIDIA_GPU_Computing_SDK-4.2
ls

• For modifying and compiling:

Unpack the tree yourself. Supply a target directory and the CUDA directory when asked. For reference, here is what happens:

$ module load cuda
$ echo $CUDA_HOME
'/opt/soft/cuda-4.2.9-1
$ ~soft/cuda/dist/4.2/gpucomputingsdk_4.2.9_linux.run

Script started, file is ./gpucomputingsdk_4.2.9_linux.log
Verifying archive integrity... All good.

Enter install path (default ~/NVIDIA_GPU_Computing_SDK):
INPUT> /home/share/soft/cuda/NVIDIA_GPU_Computing_SDK-4.2 

Located CUDA at /opt/soft/cuda-4.2.9-1
If this is correct, choose the default below.
If it is not correct, enter the correct path to CUDA

Cannot create second readline interface, falling back to dumb.
