** GENERAL FEATURES
** ------------------------------------------------------------------ */
// Use shared memory implementation. Note that the total size of the test
// must not exceed 96MB. This will be debugged later on.
#define FEATURE_SHARED_MEMORY
// Use pinned memory pages.
#define FEATURE_PINNED_MODE
// Hash size returned is trimmed to save bandwidth in the copy back.
// Check md5.h for the actual hash size returned.
#define FEATURE_REDUCED_HASH_SIZE
// This feature guesses at run time the best execution context the GPU will
// run within
//#define FEATURE_DYNAMIC_EXEC_CONTEXT
#ifdef FEATURE_DYNAMIC_EXEC_CONTEXT
// when in dynamic execution context setting, this feature will enable
// the algorithm that maximizes the number of threads rather than chunk size.
//#define FEATURE_MAXIMIZE_NUM_OF_THREADS
#endif
// Tests to run
// To run the overlap test instead of the original one.
#define FEATURE_RUN_OVERLAP_TEST
// Turn on to run SHA1, otherwise it will run MD5
#define FEATURE_RUN_SHA1
// Enable the multi-thread version for the CPU functions on windows
//#define FEATURE_WIN32_THREADS
// Enable the multi-thread version for the CPU functions on Linux (with pthreads)
//#define FEATURE_PTHREADS
