* Helper to trace gpu computed data with --cputest |
|

|
* Sample usage in an algo scan cuda unit : |
|
* |
|
* #define _DEBUG |
|
* #define _DEBUG_PREFIX "x11-" |
|
* #include "cuda_debug.cuh" |
|
* |
|
* TRACE64("luffa", d_hash); |
|
* or |
|
* TRACE("luffa") |
|
* |
|
* Dont forget to link the scan function in util.cpp (do_gpu_tests) |
