atomicAdd "Error: unsupported operation"

Hi,
I have a problem with atomicAdd for float parameters.
I compile with -gencode=arch=compute_20,code="sm_20,compute_20", and get message “Error: unsupported operation”.
Do you have any idea?

What card and what toolkit do you have?

Can I see your code?

Hello @a_goryachih! As it is related to programming so I’m completely dumb in it. We are having a fertilizer farm as our family business, both production and distribution. We too have our own website and database holding all the data related to our production. That’s why, the thing I want to say is you can take the help of IT service center that manages our complete database system. Managed IT service provider El Segundo. Also they are having their tech support center and can easily resolve your queries. Thank you.
