Any idea when we might be able to expect a CUDA 3.0/3.1 compatible release?

Actually no, you should look for a cudart.dll file under the bin directory of the CUDA installation.
If none exists, then you could create a copy of cudart32_30_14.dll file to become cudart.dll.

Hi,

I have the problem Sergio met a couple of months ago. I am trying to use CUDA Runtime methods but get the message error :

Unable to load DLL ‘cudart’: The specified module could not be found.

I had installed the toolkit and actually have a dll named “cudart32_30_14.dll”. Is it a wrong one ? I copied and pasted it in the folder containing CUDA.NET.dll but it still doesn’t work.

Am I doing something wrong ?

Thank you

I guess you have to use SetFunctionSharedSize – didn’t try it though…

Thanks!

I have another quick question. Sometimes in CUDA it is recommended to use templates to get some performance speedup. How do I pass the parameter to the template in CUDA.NET?

For example, if my CUDA function is:

template __global__ static void map(…..

How do I pass that blocksize in CUDA.NET?

Hi Sergio,

The cudart.dll file is part of NVIDIA CUDA Toolkit installation.
The driver API would work in any environment with NVIDIA drivers installed, but for the runtime API you need to install the Toolkit.

I am using your latest version of CUDA.NET. Unfortunately, when a use any of the CUDARuntime methods I get:

Unable to load DLL ‘cudart’: The specified module could not be found.

Am I missing something?
