Exploiting operating system services to efficiently checkpoint parallel applications in GENESIS

Recent research efforts of parallel processing on non-dedicated clusters have focused on high execution performance, parallelism management, transparent access to resources, and making clusters easy to use. However, as a collection of independent computers used by multiple users, clusters are susceptible to failure. This paper shows the development of a coordinated checkpointing facility for the GENESIS cluster operating system. This facility was developed by exploiting existing operating system services. High performance and low overheads are achieved by allowing the processes of a parallel application to continue executing during the creation of checkpoints, while maintaining low demands on cluster resources by using coordinated checkpointing.

Toward an operating system that supports parallel processing on nondedicated clusters

Present operating systems are not built to support parallel computing on clusters - they do not provide services to manage parallelism, i.e., to manage parallel processes and cluster resources. They do not provide support for both programming paradigms, Message Passing (MP) or Distributed Shared Memory (DSM). Due to poor operating systems, users must deal with computers of a cluster rather than to see this cluster as a single powerful computer. There is a need for cluster operating systems. We claim that it is possible to develop a cluster operating system that is able to efficiently manage parallelism, support MP and DSM and offer transparency. To substantiate this claim the first version of a cluster operating system managing parallelism and offering transparency, called GENESIS, has been developed.

Operating a studio within a research culture: the urban heart surgery design research forum

The question of whether or not design can be considered research has perplexed schools of architecture ever since they were first introduced into universities. It was at the center of the Oxbridge union debates in the early 1900s. It formed one of the corner stones of the Oxford conference on education organized by the RIBA in 1958 (Martin 1958) and came under scrutiny again in the UK with the introduction of the Research Assessment Exercise (RAE) in 1992. While the arguments both for and against are considerable1, “in order to understand the questions and the possibilities of architectural research and to respond to the difficulties that confront us now, we have to have a model which acknowledges what schools of architecture really are, and could be, and then work with that” 2.
Drawing on professionally oriented research models, such as qualitative ‘clinical research’, from Medicine and the Health Sciences - where the processes of exploration, observation, investigation, recording and communication are conducted in-situ by the ‘practitioner-as-researcher’ 3 - the following paper outlines an initiative introduced in 1999, referred to as the ‘Urban Heart Surgery’ 4. The program actively integrates students entering their second degree program into a studio based design research culture and allows them to engage in critical discourse by working on high profile strategic design projects in three areas significant to Victoria’s future growth: Metropolitan Urbanism, Urbanism on the Periphery, and Regional Urbanism.
With a growing core of industrial and community based partnerships, including: four regional councils (Bendigo, Ballarat, Geelong and Warrnambool) and three metropolitan municipalities (Melbourne City, Port Phillip and Wyndham), the forum actively facilitates a graduate/practice research agenda through the ARC linkage grant program.

Cluster operating system support for parallel autonomic computing

The aim of this paper is to show a general design of autonomic elements and initial implementation of a cluster operating system that moves parallel processing on clusters to the computing mainstream using the autonomic computing vision. The significance of this solution is as follows. Autonomic Computing was identified by IBM as one of computing's Grand Challenges. The human body was used to illustrate an Autonomic Computing system that possesses self-knowledge, self-configuration, self optimization, self-healing, and self-protection, knowledge of its environment and user friendliness properties. One of the areas that could benefit from the comprehensive approach created by the autonomic computing vision is parallel processing on non-dedicated clusters. Many researchers and research groups have responded positively to the challenge by initiating research around one or two of the characteristics identified by IBM as the requirements for autonomic computing. We demonstrate here that it is possible to satisfy all Autonomic Computing characteristics.

Into the wilderness; Gilgul's 'physical' theatre 1994

Gilgul Theatre was founded in May 1991 by director Barrie Kosky and manager flighting designer Robert Lehrer, who aimed to establish 'Australia's first professional Jewish theatre company'.

Power plays : Australian theatre and the public agenda

Power Plays capitalises on this moment of renewed and heightened interest by investigating the why and the how of eight contemporary Australian playwrights: Andrew Bovell, Patricia Cornelius, Reg Cribb, Ben Ellis, Wesley Enoch, Hannie Rayson, Stephen Sewell and Katherine Thomson. These writers are passionate about the theatre as a forum for public discussion and they interrogate current issues in their work. Their plays reflect the passing show of cultural, political and economic life in Australia, telling audiences something critical about what is going on: this is the state of play, this is what we are.

The author has conducted extensive interviews with these writers and offers an extended analysis of some of their recent plays.

Overseas Chinese as expatriate managers in China: is their recruitment a solution to cross-cultural management problems for multinationals operating in China?

This paper examines the issue of diversity in Chinese identity and how it impacts on the operations of multinationals in China who recruit Overseas Chinese to handle cross-cultural issues. China’s rapid economic development and entry into the World Trade Organization in 2001 made her a formidable player in the global economy and direct foreign investment surged. Yet it is acknowledged that for the foreign investor in China, cross-cultural issues create difficulty at every level, from the interpersonal level relating to communication and negotiation, to the organizational level relating to decision making, human resource management practices, corporate legal institutions and liaison with government institutions. Western multinationals have considered the advantages of posting Overseas Chinese from Southeast Asian countries, Taiwan and Hong Kong to their China operations as a solution to cross-cultural management issues. But has this policy been successful? In terms of language expertise this would seem to be a good strategy, yet organizational case material contradicts this in reality. Overseas Chinese, while sharing some elements of Chinese culture with mainland Chinese, the Confucian heritage and other aspects such as language and diet, nevertheless have different world views and values and behave differently from mainland Chinese in areas critical to business management. As a survival strategy, Overseas Chinese have often developed dual identities which operate simultaneously. For political and historical reasons, many of them have had to adapt to the local culture of their country of citizenship or even hide their own ethnicity in order to survive. On the other hand, the mainland Chinese are different in that their behaviour has only had to be Chinese, but overlaid with this has been the experience of participating in a communist political environment for decades, which has left its mark on mainland Chinese culture. On the basis of their different historical experiences, in the current business environment in China, cultural confusion, difficulty and conflict may occur for the Overseas Chinese.

This paper focuses attention on the subtle cultural differences between the Overseas Chinese and mainland Chinese in an organizational context. This problem has yet to be researched in depth within international business and international management studies. It provides evidence that Overseas Chinese are not often favoured by the local Chinese. It gives insights on how to manage the local Chinese for foreign multinationals operating in China.

Simulation of the solar adsorption refrigeration operating at near atmospheric pressure

To solve the leaking problem faced by current vacuum adsorption refrigeration systems, the authors have carried out a series of studies on the concept of raising the system's pressure to around atmospheric pressure with an inert gas (eg. Helium) as the pressure-adjusting agent. This paper presents the simulation of the performance oj the activated carbon-methanol adsorption refrigeration operating at near atmospheric pressure powered by solar energy. This simulation can be refereed in the prototype design.

Celebrates the company's artistic achievements and successes over the last two decades through interviews, essays and high quality images of key productions, and recounts its history, its evolving relationship with the embattled trade union movement, and its on-going engagement with working class, indigenous and migrant communities.

'Class' and political theatre : the case of Melbourne workers theatre

Traditionally, class has been an important category of identity in discussions of political theatre. However, in recent years the concept has fallen out of favour, partly because of changes in the forces and relations of capitalist production. The conventional Marxist use of the term, which defined an individual's class position in relation to the position they occupied in the capitalist production process, seemed anachronistic in an era of globalization. Moreover, the rise of identity politics, queer theory, feminism, and post-colonialism have proffered alternative categories of identity that have displaced class as the primary marker of self. Glenn D'Cruz reconsiders the role of class in the cultural life of Australia by examining the recent work of Melbourne Workers Theatre, a theatre company devoted to promoting class-consciousness, in relation to John Frow's more recent re-conceptualization of class. He looks specifically at two of the company's plays, the award-winning Who's Afraid of the Working Class? and The Waiting Room, with reference to Frow's work on class, arguing that these productions articulate a more complex and sophisticated understanding of class and its relation to politics of race and gender today.
