The CUDA (Compute Unified Device Architecture) SDK can be used to write programms running on NVIDIA GPUs. All Most workstations in CIP2 have CUDA installed, the workstations have aliases "cuda1"-"cuda9cuda7".

These machines are used for the CUDA seminar that is usually offered in the summer semester.


We have one GeForce GT 1050 with CUDA capability 6.1, a GeForce GTX 960 with CUDA capability 5.2, a GeForce GTX 780 with CUDA capability 3.5, a GeForce GT 640 with CUDA capability 3.0 and a couple of others.

cont3iseven1 | X | GeForce GT 630 (these older cards will be removed)
cont3iseven2 | X | GeForce GT 710
cont3iseven3 | X | GeForce GT 560 Ti

You can find out about the CUDA capabilities of the card in your workstation with the deviceQuery program from the samples directory:

Local users can also try the graphical examples in /mount/share/cuda-samples, there are the binaries, the source code and quite a lot of documentation. Compiling your own programs has become a lot easier since CUDA5, in the past we needed to make lots of modifications to the Makefiles, but now there are just a few changes. After you have copied the source files to your home directory, change the line

INCLUDES      := -I$(CUDA_INC_PATH) -I. -I.. -I../../common/inc


INCLUDES      := -I$(CUDA_INC_PATH) -I. -I.. -I$(CUDA_PATH)/samples/common/inc

(necessary because the includes of the samples are in the cuda tree, not in your HOME.) Also, you should comment out (or delete) the lines that make a copy of the finished binary,

#       mkdir -p ../../bin/$(OSLOWER)/$(TARGET)
#       cp $@ ../../bin/$(OSLOWER)/$(TARGET)

This way you should be able to compile everything by typing make. (If you are compiling some of the graphical examples, you also need to replace






Excellent Documentation is available at the NVIDIA homepage. You should check out this extensive site. But for starters it should be enough to read Getting_Started. Last but not least, don't forget to checkout the webinars.
