Go up one level in this thread
i have made a wrapper class for the lock/unlock operations
that i do at a struct SPLIT.
SPLIT
{
//HANDLE lock;
CRITICAL_SECTION cs;
other data...
}
At codeguru site i read that critical sections are faster than
mutexes.But for me they are *very very slower*. I am sure i am doing something
wrong but don't know what?
Another question is how profitable is using methods like InterLockedExchange,
i mean going low level, for SMP chess engines?
SPLIT::SPLIT()
{
//lock = CreateMutex(NULL,0,NULL);
InitializeCriticalSection(& cs);
}
SPLIT::~SPLIT()
{
//CloseHandle();
DeleteCriticalSection(& cs);
}
SPLIT::Lock()
{
//WaitForSingleObject(lock,INFINITE);
EnterCriticalSection(& cs);
}
SPLIT::UnLock()
{
//ReleaseMutex(lock);
LeaveCriticalSection(& cs);
}
best
