We report the realization of the first cosmological simulations on the scale of the whole observable universe. These simulations have been carried out on 4752 nodes of the Curie supercomputer as a part of the Dark Energy Universe Simulation: Full Universe Runs (DEUS-FUR) project which aims at establishing new probes to put constraints on the nature of dark energy by comparing the growth of large-scale structures, the characteristics of extreme statistical events and the matter distribution in redshift space. The numerical challenge of the first DEUS-FUR simulation associated with the concordance LCDM (L Cold Dark Matter) model was already presented during the 2012 supercomputing conference (Alimi et al., 2012, in The international conference for high performance computing, networking, storage and analysis).Here we first focus on the numerical aspects of the two new simulations. In practice, each one of these simulations has evolved 550 billion dark matter particles in an adaptive mesh refinement grid, and one of the new simulations has pushed back the total number of grid points from 2000 billion for the LCDM model to 2200 billion due to the formation of a larger number of structures. We highlight the optimizations and adjustments required to run such a set of simulations and we then summarize some important lessons learnt for future exascale computing projects.

Housing refers to both the physical product and the process of its attainment. Housing is perceived according to its performance and its usefulness varies with the level of comfort and hygiene it provides. The importance of people in housing is recognised not when housing complies with municipality by laws, but when people live in it and is acceptable in a community. Housing also means privacy and is an expression of ways of life, aspirations and social cultural relationships. Therefore, housing is the provision of comfortable shelter with available infrastructure, services and facilities that address people's needs. Sarbagita metropolitan, Indonesia has large affordable housing provided by both public and private developers. In fact, the fast growing affordable housing projects have not assured the delivery of better quality of physical, infrastructure and public facilities. This paper will try to investigate the role of households as consumers and the role of developers in providing better quality low-cost housing projects in Sarbagita. By using some indicators, the various modes of affordable housing projects provision in Sarbagita Metropolitan Bali will be examined, including public and private housing projects. The data were gathered using observations, interviews, questionnaires and documentation techniques from project sites, stakeholders, developers and dwellers. Data collected were then analyzed qualitatively to make findings and draw conclusions and recommendations. The result shows that the low-quality affordable housing provision is often unsuitable for dwellers because of developer constraints, and the lack of power or means of households to direct or influence the inception or delivery of the projects. Some recommendations will be proposed in this paper in order to improve the quality of affordable housing projects provision for dwellers in Sarbagita metropolitan.
