Abstract

Procédé et dispositif détectant les situations de blocage survenant au cours de l'exécution de N tâches. Une zone de N + 1 index est créée dans un registre tenant compte des relations d'attente parmi les tâches, une position arbitraire j recevant l'index j. Les positions de ces index sont modifiées au cours d'opérations d'itération. La détection d'au moins un index non-j indique une situation de blocage. L'invention permet de détecter les situations de blocage en considérant uniquement les relations d'attente entre les tâches et avec un minimum d'itérations.
