Techniques for Wrapping Scientific Applications to CORBA Components

In the computer aided engineering field high performance computing clusters are essential for today's work. In order to use them efficiently, monitoring systems are required. There are a lot of software systems for different monitoring purposes. The task of managing all of them at the same time usually becomes very complex, because they all have different administration requirements. In order to reduce the complexity and thus increase the manageability of high performance computing clusters for engineering applications, we propose a solution that bundles all monitoring activities into a single monitoring environment based upon an integration platform.As the base of the monitoring environment, the distributed integration platform RCE (Reconfigurable Computing Environment) is chosen. Thereby, many things like distribution or privilege management are already available. As it is a requirement to reuse existing monitoring techniques, two techniques are exemplarily examined, and a concept is developed how to embed them into the Reconfigurable Computing Environment.In this paper we describe the concept of an embedded monitoring environment for multiple purposes that reuses existing monitoring techniques.

“…In the field of High Performance Computing (HPC) and Grid Computing, Forkert et al ( [3]) present the TENT framework for wrapping applications as components. However, this wrapping is only used to better organize applications, and not to provide an integrated framework in which offer services to component implementations.…”

The design and implementation of distributed High Performance Computing (HPC) applications is becoming harder as the scale and number of distributed resources and application is growing. Programming abstractions, libraries and frameworks are needed to better overcome that complexity. Moreover, when Quality of Service (QoS) requirements such as load balancing, efficient resource usage and fault tolerance have to be met, the resulting code is harder to develop, maintain, and reuse, as the code for providing the QoS requirements gets normally mixed with the functionality code. Component Technology, on the other hand, allows a better modularity and reusability of applications and even a better support for the development of distributed applications, as those applications can be partitioned in terms of components installed and running (deployed) in the different hosts participating in the system. Components also have requirements in forms of the aforementioned non-functional aspects. In our approach, the code for ensuring these aspects can be automatically generated based on the requirements stated by components and applications, thus leveraging the component implementer of having to deal with these non-functional aspects. In this paper we present the characteristics and the convenience of the generated code for dealing with load balancing, distribution, and fault-tolerance aspects in the context of CORBA-LC. CORBA-LC is a lightweight distributed reflective component model based on CORBA that imposes a peer network model in which the whole network acts as a repository for managing and assigning the whole set of resources: components, CPU cycles, memory, etc.

Software developments in a scientific environment often serve a very special purpose and a limited number of users. When need arises to make the software usable in a more general way, the software has to be improved in terms of quality and meeting the users' needs. To apply it for a longer period, it also has to take into account changes of state-of-the-art software and technologies. This paper describes an example for such an evolution of scientific applications over the course of ten years. Developed initially as an environment for a specific numerical simulation project, the software has been applied to other simulation projects in various sectors. Keeping a relative stable software design, more functionality and features have been added. New features make use of emerging technologies and widen the application range. The development of software engineering methods and tools has been steadily evaluated and the software development environment has been adapted accordingly.11th European Conference on Software Maintenance and Reengineering (CSMR'07) 0-7695-2802-3/07 $20.00
