Define Documentation

#define FLT_TYPE   long double

We need big precision because 10.000 additions. With 'float', we get this error : Erreur 4.99944e+07 != 4.99929e+07 With 'double', it is OK on Linux. But fails on Cygwin. Differents libraries ?

#define MAX_STATIC_SZ   ( 1000000 * TST_RATIO )

In debug mode, it would be fine to have a counter on each thread, just to check that the CPU load is well balanced. Even with 'long double', precision problems over 200000 The constant TST_RATIO adjusts the tests duration.

Various sizes because the algorithm dynamic sizing adapts to the data size.

template<class ThrTree>

void TstCharsAux	(	ThrTree	aThrTree,
		char	aInit,
		const char *	aStr
	)

Only lowercase letters : All the other ones are checked, and means there was an error somewhere. The comparison tests work only if all letters are different.

Variable Documentation

rpa::mutex_count< rpa::sample_mutex_type > aLock

These containers are used ase inputs.

This mutex is used for 'range_step'. It is encapsulated in a counter of locks/unlocks, to check how many times it is used.

FLT_TYPE myF[NB_FLOA] [static]

Global variable because if is put on the stack, it may crash everything.

FLT_TYPE SUM_FLOA = (( NB_FLOA_FLT * ( NB_FLOA_FLT - (FLT_TYPE)1))/ (FLT_TYPE)2.0)
