hello everybody,
is there any command from linux bash to know the type of architecture of the nvidia graphic device installed in the system?
i mean number of cores, device memory size, shared memory size in every SM, etc…
the other idea was: given the type of graphic device, look for a datasheet…
but i’ve only seen a brief description on nVidia website.
maybe it’s a stupid question, i’m pretty new with cuda programming…
thanks
The CUDA SDK includes a command called deviceQuery that does exactly that and give output like this:
CUDA Device Query (Runtime API) version (CUDART static linking)

thanks!!
i think i’ve read this somewhere in the programming guide or in the gettin’ started document,
but of course i forgot when i needed… External Image
