Re: [Starpu-devel] registering handles

[Hatem Ltaief <hatem.ltaief@kaust.edu.sa>]

Hi Sam,
I am printing the indices in the inner loop and it does complain only at the 
second iteration of the outer loop. If this was not initialized, it would 
have complained right away, right?
But wait, by initialize, do u mean registered handle via starpu or memory 
allocation?
Thanks
