whats is the size of extern __shared__ float share memory

i can not use sizeof…
as i know THAT the size of the array is determined at launch time


kernel_call<<<gridDim, blockDim, sharedMemSize>>>()
You specify it yourself

And you can pass that size as an integer parameter to your kernel, if the amount of shared memory to use cannot be derived from other kernel parameters.

Yes I am starting to understand…
10x ALL

:wub: love you all :geek: :wub:
