I came across a strange issue with Nsight. I should not say this is the problem with Nsight but there is some thing which is not allowing me to increase the input size beyond 353 X 353. The attached image shows the error message that pops up when i try to go beyond 353 X 353. Please find some time to see through this issue.
Did you forget to attach the image in your previous post?
Could you also attach a reproducible and compilable project for us to take a look at it? You can send the project to me at dtoh@nvidia.com if you do not wish to attach the project files in the forum.
