Electrifying public bus transportation is a critical step in reaching net-zero goals. In this paper, the focus on problem of optimal scheduling an electric (EB) fleet to cover transport timetable. The modelled using mixed integer program (MIP) which charging time EB pertinent battery’s state-of-charge level. To be able solve large instances corresponding real-world applications model, metaheuri...

In this work, by using dynamic analysis techniques, we analyze how a workload can be accelerated in the case of a shared-bus shared-memory multiprocessor. It is well known that, in this kind of systems, the bus is the critical element that can limit the scalability of the machine. Nevertheless, many factors that influence bus utilization have not been yet investigated for this kind of workload,...

Universal Serial Bus (USB) is a popular standard for PC peripheral devices because of its versatile peripheral interconnection specifications. USB not only provides simplified hardware connectors but also supports for various bus traffics, such as isochronous and bulk transfer activities. Although the USB specifications provide a way for users to specify the upper bound on the number of bytes f...

Consider a scheduling problem of parallel computations in multiproces-sor systems. Let a parallel program be represented by a task graph, where vertices represent tasks and arcs represent the communications between the tasks. An in-terprocessor communication time incurs when two tasks assigned to two diierent processors have to communicate. Such a scheduling problem has recently been studied in...

A reconfigurable wavefront array rDPA (reconfigurable datapath architecture) for evaluation of any arithmetic and logic expression is presented. Introducing a global I/O bus to the array simplifies the use as a coprocessor in a single bus oriented processor system. Fine grained parallelism is achieved using simple reconfigurable processing elements which are called datapath units (DPUs). The wo...

In order to develop a sustainable datacenter, which would help to validate energy management and task scheduling algorithms, a low voltage direct current (LVDC) microgrid (MG) has been deployed in the ADREAM Building-Integrated Photovoltaic (BIPV) of the LAAS-CNRS in Toulouse, France. This MG is composed of a 1 kWp PV source, 300 Ah – 36 V lead-acid batteries, 330 F – 48 V supercapacitor (SC) p...

The electrification of public transport bus networks can be carried out utilizing different technological solutions, like trolley, battery or fuel cell buses. The purpose of this paper is to analyze how and to what extent existing bus networks can be electrified with fast charging battery buses. The so called opportunity chargers use mainly the regular dwell time at the stops to charge their ba...

In this paper we address the test scheduling problem for system-on-chip. Different from previous approaches where it is assumed that all tests will be performed until completion, we consider the cases where the test process will be terminated as soon as a defect is detected. This is common practice in production test of chips. The proposed technique takes into account the probability of defect-...

In this paper we reformulate the thread scheduling problem on multiprogrammed SMPs. Scheduling algorithms usually attempt to maximize performance of memory intensive applications by optimally exploiting the cache hierarchy. We present experimental results indicating that contrary to the common belief the extent of performance loss of memory-intensive, multiprogrammed workloads is disproportiona...
