** 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
