I use CUDA on my desktop for some of my programs. My desktop runs Ubuntu 9.04 and has a NVIDIA GPU, so I managed to do the installation after reading a few tutorials online.

However, I would like to continue editing my code on my laptop. The laptop runs Ubuntu 10.04 and this is the description of its GPU from lshw


*-display:0
description: VGA compatible controller
product: Mobile GM965/GL960 Integrated Graphics Controller
vendor: Intel Corporation
physical id: 2
bus info: pci@0000:00:02.0
version: 0c
width: 64 bits
clock: 33MHz
capabilities: msi pm bus_master cap_list rom
configuration: driver=i915 latency=0
resources: irq:29 memory:e4600000-e46fffff
memory:d0000000-dfffffff(prefetchable)
ioport:4000(size=8)


How do I install CUDA on this machine? I cant seem to find any tutorials online on how to install it in machines which do not have a nvidia graphics chip?

Thanks for the help

You cant install CUDA on a machine without a nVidia 8XXX series or higher GPU.

No way that it is going to work with an Intel GPU.

are you sure??

i was reading on the nvidia forums that you can run it in some sort of emulation mode.... but the guys there dont say how to do that!

Ther might be a hack to make it work on Intel GPUs, but I doubt it.

More likely that it would work on ATI, since Intel GPUs are always a few generations behind ATI/nVidia.

Compile with -deviceemu

This will cause the program to start up a bunch of pthreads and utilize those as if they were individual cores, all on your cpu.

for cross platform GPU programming you want openCL rather than CUDA.

I looked around for opencl.... however I could not find anything on how to install it in ubuntu....

another problem is that I couldnt even find anything on their website which looked remotely similar to "get sdk"

so i dont know really.... do you have any idea how to install it in ubuntu 10.04 64bit?
