Cheers,  
The below command in my Julia 1.6.7 / CUDA v3.12.0 system:

> CUDA.device()

has the answer:

> CuDevice(0): NVIDIA GeForce RTX 2060

However, when printing or storing the output on a variable,

> println( CUDA.device() )  
> x = CUDA.device()

the displayed answer is just:

> CuDevice(0)

Would appreciate any support, as to obtain full answer. Thanks.

The REPL prints things differently, the same applies to e.g. array objects. You can use the `display` function if you want REPL-style output from a script.

For printing, OK. For storing the info on a variable, or on a data frame (which is the actual application), the variable apparently retains only the short form. Thus, we loose the information.

Is there a way to get GPU info from within Julia, without loosing such info?

Thanks.

That seems like a weird thing to do. Why don’t you query the name directly (`CUDA.name(::CuDevice)`) instead of relying on the I/O routines?

That works, thanks.
