Description

Hi~ I found the function of len() is invalid to dynamic share array. Here is my code snippet:

@cuda.jit
def kern_fun()
    dynamic_share_array = cuda.shared.array(0, numba.float32)
    fill_value(dynamic_share_array)
    print(len(dynamic_share_array))

main():
    kern_fun[1, 10, 0, 100]()

the output of print is '0'. Any ideas?

Contributor guide

Research direction
Examine the implementation of len() for dynamic shared arrays in Numba's CUDA target. Trace how cuda.shared.array(0, dtype) allocates and tracks size.
