“…If a LMS intends to encompass and an evaluation system, its design and architecture will grow in complexity and a poor designing can lead to a jam. An important factor and problem in designing software architecture for this type of system is the scalability as a solution to the given question "How well a solution to some problem will work when the size of the problem increases" [32]. Of course this leads us to one of the conclusion that the storage space and storage location are very important.…”

“…The response time defined as "a measure of the latency an application exhibits in processing a business transaction. Response time is most often (but not exclusively) associated with the time an application takes to respond to some input" [33] is very important when we associate it with the evaluation process, because all evaluations are timed. The evaluation process is much more complex than it looks.…”

“…This can differ from each university, country or area and this can raise a problem when scholarship programs are involved in evaluation and equalization. The performance factor "defines a metric that states the amount of work an application must perform in a given time, and/or deadlines that must be met for correct operation" [34]. When an admission deadline is on the field, the crucial factor concerns the performance of the system, along with the number of simultaneous connections.…”

“…Non-functional requirements, also called quality attributes, are concerned with how a system provides its functionality [8], and they become increasingly important for larger systems. ITSs are no exception: the internal structures and models for representing knowledge determine important non-functional qualities such as reusability, modularity, and maintainability.…”

Abstract. An intelligent tutoring system (ITS) is often described as having an inner loop for supporting solving tasks step by step, and an outer loop for selecting tasks. Many task domains have problem-solving procedures that express how tasks can be solved by applying steps or rules in a controlled way. In this paper we collect established ITS design principles, and use the principles to compare and evaluate existing ITS paradigms with respect to the way problem-solving procedures are specified. We argue that problem-solving procedures need an explicit representation, which is missing in most ITSs. We present an extensible domain-specific language (DSL) that provides a rich vocabulary for accurately describing procedures. We give three examples of tutors from di↵erent task domains that illustrate our DSL approach and highlight important qualities such as modularity, extensibility, and reusability.

SUMMARYEvent services based on publish-subscribe architectures are well-established components of distributed computing applications. Recently, an event service has been proposed as part of the common component architecture (CCA) for high-performance computing (HPC) applications. In this paper we describe our implementation, experimental evaluation, and initial experience with a high-performance CCA event service that exploits efficient communications mechanisms commonly used on HPC platforms. We describe the CCA event service model and briefly discuss the possible implementation strategies of the model. We then present the design and implementation of the event service using the aggregate remote memory copy interface as an underlying communication layer for this mechanism. Two alternative implementations are presented and evaluated on a Cray XD-1 platform. The performance results demonstrate that event delivery latencies are low and that the event service is able to achieve high-throughput levels. Finally, we describe the use of the event service in an application for high-speed processing of data from a mass spectrometer and conclude by discussing some possible extensions to the event service for other HPC applications.
