Full textThis thesis deals with the scheduling of tasks on parallel machines with unavailability constraints. Such a problem might be encountered in parallel computing, or in management of a production floor. The unitary execution time tasks scheduling problem is fundamental because it can be solving very efficiency. It is useful for the resolution of arbitrary duration tasks scheduling problem. There is a narrowest gap between the preemptive unitary execution time tasks scheduling problem and the arbitrary execution time tasks scheduling problem. If the durations of the tasks are bounded, we can use it to find lower bound for the general problem

Full textAfter a state of art on classical scheduling and on real-ime scheduling, particularly, allowing to define the notions used afterwards and after motivating a new real-time constraint of latency, we propose a model which describes the real-time systems with precedence, periodicity and latency constraints. In this model, the precedences are defined using a directed acyclic graph. In the monoprocessor case, we study three problems of scheduling: systems with precedence and periodicity constraints, systems with precedence and latency constraint and systems with precedence, periodicity and latency constraints. For each problem we study the relation between the precedences and the periodicity, respectively the latency, we give schedulability conditions and we propose scheduling algorithm which are proved optimal (if there is a schedule, the algorithm will find it). For the multiprocessor case the architecture is defined by a non-oriented graph. We study three multiprocessor scheduling problems: of systems with precedences and periodicty constraints, of systemes with precedences and latency constraints and of systems with precedences, periodicity and latency constraints. For each problem the model takes into account the communications. We prove that each problem is NP-hard and we propose heuristics. The performances of each heuristic is compared to those of an exact algorithm of type branch and bound, using numerical simulations

Full textIn this thesis we studied the problem of multiprocessor preemptive real-time scheduling taking into account the exact cost of the operating system (OS). This cost is composed of two parts: a part easy to determine, corresponding to the scheduler cost and another part difficult to determine, corresponding to the preemption cost. This difficulty is due to the fact that a preemption can involve another one, being able to so create an avalanche phenomenon. First, we studied the off-line multiprocessor real-time scheduling of independent tasks taking into account the exact preemption cost. We proposed a schedulability analysis based on a multiprocessor scheduling heuristic. This heuristic uses the partitioned multiprocessor scheduling approach. In order to take into account the exact preemption cost on every processor we use the schedulability condition proposed by Meumeu and Sorel. This schedulability condition for fixed priorities tasks, is based on a binary scheduling operation which counts the exact number of preemptions and add their cost in the schedulability analysis. The proposed heuristic maximizes the remaining utilization factor to fairly distribute the tasks on processors and to reduce their response time. It produces an off-line scheduling table. Secondly, we studied the off-line multiprocessor real-time scheduling of dependent tasks taking into account the exact preemption cost. Because the schedulability condition used for scheduling independent tasks can be applied only to fixed priorities tasks, it does not allow to manage priorities inversions that are involved by dependent tasks. We proposed a new schedulability condition for dependent tasks which enables fixed and dynamic priorities. This schedulability condition takes into account the exact preemption cost and dependences between tasks without any loss of data. Always with the partitioned scheduling approach, we proposed for dependent tasks a multiprocessor scheduling heuristic which reuses, on every processor, the schedulability condition proposed previously. In addition, this scheduling heuristic takes into account the interprocessors communication costs. It also minimizes on every processor the makespan (total execution time of the tasks on all the processors). This heuristic produces for every processor an off-line scheduling table. Supposing that we have a time-triggered multiprocessor architecture such that all the processors have a unique time reference, we proposed for every processor an on-line scheduler which uses the scheduling table produced during the off-line schedulability analysis. This on-line scheduler has the advantage to have a constant cost that is easy to determine exactly.Indeed, this cost corresponds only to the time necessary to read in the scheduling table the task selected for execution. In the on-line classical scheduler, this cost corresponds to the time necessary to update the list of ready tasks in order to select a task, according to a given scheduling algorithm, for example RM, DM, EDF, etc. In this case, the cost for selecting a task varies with the number of ready tasks which changes from an invocation of the scheduler to another one. Another advantage of the proposed on-line scheduler is that it is not necessary to synchronize the access to the data shared by several tasks, because this synchronization was already done during the off-line schedulability analysis

Full text@Hard real-time scheduling theory has been widely studied in the last twenty-five years. Despite the plethora of results, few are oriented towards a performance comparison of the algorithms. Rather than taking account of new specific constraints, we focus on a generic traffic model for centralized, preemptive/non-preemptive cases. We first analyse the traditional fixed/dynamic priority approaches for feasibility and optimality properties. .

Full textProperty right (jus proprietatis) and contractual freedom establish the right for every owner to choose the person to whom he may wish to sell his property. There are nevertheless hypotheses where the legislator granted to some persons, by his own authority, a right of pre-emption which allows them to be preferred to others when concluding the sale contract. Right of preemption remains, however, a badly known and controversial institution, as the legislator established a very great quantity of rights of preemption, according to his political ambitions, and endowed each of these rights of a specific legal regime. The fact that he hardly worried to confer on them any coherence generates many conflicts between rights of preemption, or between a right of preemption and another legal institution. Besides, general interest, which justifies right of preemption and requires that its domain be limited to strict minimum as well as the guarantees granted to the concerned persons, does not dissuade the legislator to strengthen constantly the influence of this institution. These data, which illustrate the purposes of right of preemption, do inevitably influence its notion : indeed, they lead to consider that the service expected from the seller, which is to propose by priority the acquisition of his property to the beneficiary, is constituting the basis of right of preemption. The regime and the effectiveness of all the rights of preemption are based upon that service. It becomes then possible to suggest a new definition of right of preemption and to establish its legal nature from property right. Two criteria of delimitation of right of preemption can be also proposed, the first one resting on its legal source, the second resulting from the determination of the moment of its intervention, which is not without practical consequence

Full textThe rapidity of the diagnosis of candidaemia and invasive candidiasis (IC) is crucial to allow the early introduction of antigungal therapy. This one is often delayed because Candida yeasts are found in blood culture, the gold standard diagnostic test, in only 50% of cases of IC and several days are needed to have this result. Complementary methods relie on the detection of Candida cell wall polysaccharids in the serum, β-glucans (BDG) and mannans (Man). Our objectives were to : a) determine the signification and clinical interest of the detection of BDG and Man in intensive care b) take part in the analysis of the interest of a mass spectrometry (MS) technic in development which aim to detect/caracterize circulant fongic glycans. Materials and Methods : a) For the clinical case-control study, the BDG and Man kinetics in relation with candidaemia were evaluated in 41 candidemic patients, and were compared to the kinetic observed in 67 non candidemic patients, hospitalised in the same ward and assessed weekly for yeast colonisation b) a MALDI-MS method was applied to sera after selective extraction of glycans and compared to standards. Results : BDG at the recommanded cut-off is a sensitive and precoce but non specific test for the diagnosis of candidemia in ICU. It does not seem to be affected by the colonisation, but its very slow decrease limits its usefulness for the management of the treatment. At the opposite, Man is very specific but not sensitive. Modulating the cut-off of BDG, it is possible to propose a decisional algorithm for preemptive therapy based on the sequential use of BDG and Man. b) MALDI-MS reveals a signal at position m/z 365, corresponding to a disaccharid (among which is trehalose), associated to human and experimental IC. In preliminary studies this test seems to have good sensitiity and specificity for the diagnosis of IC as well as for other fungal infections. Conclusion : a) BDG is a sensitive test, Man is a specific one, and their joint use could be useful for an early diagnosis of IC and a rationalization of the antifungal treatment. b) The application of MALDI-MS method to the detection/caracterisation of circulating glycans seems to present an important potential to replace or complete the current available diagnostic tools of IC
