|
* 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)
