I want to perform CUDA operation in LabVIEW to transfer multiple files in GPU in parallel and then perform arithmetic operations on GPU and then save the data in new file. I learnt that in order to perform operations in GPU, we need to create a DLL file and then import it to LabVIEW but I don't know how. Can you give me some example of a similar operation?

LabVIEW has no support of CUDA, as you said. Calling DLL in LabVIEW is quite easy, Use the Call Library Function node for this purpose.

Even easier, once you've written the dll, have LabVIEW generate VI wrappers around your DLL by entering the wizard in Tools menu -> Import -> Shared library

See also this article that explains things quite extensively.

  • But I am not able to make a dll file to be imported from LabView. Can you plz explain the way to do it or if you have a sample code, can you plz share it with me? Thanks for your help. – Paritosh Sep 29 '11 at 01:16
  • Unfortunately I don't have time to write code for you. You can find a lot of references on the [link I added](https://decibel.ni.com/content/docs/DOC-9076) to my answer. If you have problems come back here to get some help! – CharlesB Sep 29 '11 at 07:24

NI should also has a set of CUDA VIs available on their site. I don't know if those would help in your case, since you already seem to have the C code, but it might.

  • Do you have a link to these VI's? – CharlesB Sep 28 '11 at 10:13
  • Ya NI has got some CUDA VIs but that is insufficient, I can just add arrays into the GPU but now I want to do operations on those array data and I am finding it difficult. Can you help me out plz.. – Paritosh Sep 29 '11 at 01:17

Yes, NI can provide support. Please join this community group. There is a library that you can install so you can have CUDA support in LabVIEW. Also, please post questions to this community group for help if needed.
