If you ignoe this advice and still want to create "singletons" threads at least use QApplication::instance(); as the parent of the thread and put QThread::wait() in the singleton destructors otherwise your program will crash at the program exit. if(!s_instance){ QMutexLocker lock(&m...
All classes in my DAL are Static because I thought this is a good way of improving performance (not having to create new class instances for every little operation). And all my DAL classes use the same "root" DAL class which builds Connections: publicstaticclassMySQLConnectionBuilder{privatesta...
The following domains are indicated: EXO, domain harboring exonuclease activity, homologous to RNase D (in Rrp6) or RNase II/R (in Rrp44, RNB domain) from Eubacteria; ENDO, domain harboring endonuclease activity in Rrp44 (PIN, PilT N terminus); HRDC, helicase and RNase D C-terminal ...
When two threads simultaneously contend a lock (in this case,locker), one thread waits, orblocks, until the lock becomes available. In this case, it ensures only one thread can enter the critical section of code at a time, and “Done” will be printed just once. Code that's protected ...
The wordLookup.Contains method in the predicate gives the query some “meat” and makes it worth parallelizing.We could simplify the query slightly by using an anonymous type instead of the IndexedWord struct. However, this would degrade performance because anonymous types (being classes and ...
Many methods of the managed threading classes provide time-outs to help you detect deadlocks. For example, the following code attempts to acquire a lock on the current instance. If the lock is not obtained in 300 milliseconds, Monitor.TryEnter returns false....

The comparative modeling approach to protein structure prediction inherently relies on a template structure. Before building a model such a template protein has to be found and aligned with the query sequence. Any error made on this stage may dramaticall
To create a thread in the Win32 application programming interface (API), you call CreateThread. With Microsoft Foundation Classes (MFC), you call AFXBeginThread. You can also use the C runtime function _beginthread, which has fewer parameters than the CreateThread call. The thread function is ...
A thread is analogous to the operating system process in which your application runs. Just as processes run in parallel on a computer, threads run in parallel within a single process. Processes are fully isolated from each other; threads have just a limited degree of isolation. In particular,...
