Hi, sorry it was 3:00 AM.


- ocl_gpu_id is a sequential number (only one; for legacy code)
- ocl_device_list is a (array) list of sequential numbers.
- And ocl_gpu_id = ocl_device_list[0]

BTW: name renames might be advisable. I don't like the ocl_gpu_id, 
someone else would not like the ocl_device_list[] name.
BTW 2: it is not really hard to start devices from 1 (not zero). It will 
impact only common ('my') code. You don't need to care about it.
