We'll try to send something, I'm out of the office, let's see if Vicente can send it.
I think the best is to send the sandbox we've been using for test and development of the different prefix sum scans versions. He's the one who programmed them, I think he had done so in CUDA C and made a translation to CUDA Fortran.

Best Regards,

If you want to run it in the code we already sent I think you need to comment the lines call exclusive_int_scan() , and uncomment the call fast_exclusive_int_scan() . which is the one we are asking the questions about...
I'm not sure what changes Vicente may have done today -or even if he did any- :-)

Vicente tells me that probably the version you have of the fast scan has couple of bugs, he'll send the fixed version soon

Ups...turns out we had a small memory leak, Vicente has fixed that already.
Thanks for the help and sorry for bothering you.

Best regards,
