end offset is before start offset Value Error

[Bobby Garza]

I'm pretty sure this error has something to do with my stride and loop conditions, but i'm not sure what to change to fix this. I use the built in function for my start and the built in function for my stride.

start  = cuda.grid(1)

stride = cuda.gridsize(1)

my for loop looks like:

for i in range(start, list_of_vals.shape[0], stride): 

list_of_vals is a numpy array i pass my function from main() and the call to shape should give the loop the right size, but this isn't happening. 

Am I missing something simple or does this error mean there's something extremely wrong? 

I appreciate any help!
