Development Processes

This chapter investigates the quality issues of the free and open source software (F/OSS) development processes. It argues that software developed within the F/OSS paradigm has witnessed substantial growth rates within the software developers’ community. However, end users from outside the community are still sceptical about adopting F/OSS because of the perceived lack of quality assurance mechanisms within the F/OSS development process. The authors aim to promote higher adoption of F/OSS artefacts outside the developers’ community by exploring possibilities to provide appropriate evidence based assurances that F/OSS artefacts will meet the quality levels expected by users.

This chapter aims to contribute to our understanding of the free/libre open source software (FLOSS) innovation and how it is shaped by and also shapes various perceptions on and practices of hacker culture. Unlike existing literature that usually normalises, radicalises, marginalises, or criminalises hacker culture, I confront such deterministic views that ignore the contingency and heterogeneity of hacker culture, which evolve over time in correspondence with different settings where diverse actors locate. I argue that hacker culture has been continuously defi ned and redefi ned, situated and resituated with the ongoing development and growing implementation of FLOSS. The story on the development of EMACSen (plural form of EMACS—Editing MACroS) illustrates the consequence when different interpretations and practices of hacker culture clash. I conclude that stepping away from a fi xed and rigid typology of hackers will allow us to view the FLOSS innovation from a more ecological view. This will also help us to value and embrace different contributions from diverse actors including end-users and minority groups.

This article aims to contribute to our understanding of the free/libre open source software (FLOSS) innovation and how it is shaped by and also shapes various perceptions on and practices of hacker culture.

The author argues that hacker culture has been continuously defined and redefined, situated and resituated with the ongoing development and growing implementation of FLOSS. The story on the development of EMACSen (plural form of EMACS—Editing MACroS) illustrates the consequence when different interpretations and practices of hacker culture clash. The author concludes that stepping away from a fixed and rigid typology of hackers will allow people to view the FLOSS innovation from a more ecological view. This will also help people to value and embrace different contributions from diverse actors including end-users and minority groups.

This study seeks to understanding the growth and popularity of Open Source Software (OSS) development for simulation modeling under Science and Engineering domain on SourceForge online service platform. The objectives include understanding the importance, if any, of the features such as, license type, programming language, Operating System version, review rating in influencing the popularity of a given software application as measured by downloads. For obvious reasons, end-users select and adopt specific applications based on their usage needs and the suitability of a given application in meeting their needs. Nevertheless, some applications may be easily adoptable than the other given the different options available for customization as well as scalability opportunities present in an application. So, other factors remaining common, popularity gained by an application with the increased downloads tends to draw prospective users to a specific application more than the others. This study analyses the availability and accessibility of simulation modeling software on the Source Forge website, undeniably, a very large repository of open source software resources. Limiting the search to “Simulations” within “Science and Engineering” domain /category. The top 250 applications’ data is downloaded and analyzed. Useful insights and metrics are developed and compiled to assist end-users to understand the profile of open source simulation applications available for users for free downloads.

Performance Computing

In order to guaranty performances of complex systems using numerical simulation, CEA is performing advanced data analysis and scientific visualization with open source software using High Performance Computing (HPC) capability. The diversity of the physics to study produces results of growing complexity in terms of large-scale, high dimensional and multivariate data. Moreover, the HPC approach introduces another layer of complexity by allowing computation amongst thousands of remote cores accessed from sites located hundreds of kilometers away from the computing facility. This paper presents how CEA deploys and contributes to open source software to enable production class visualization tools in a high performance computing context. Among several open source projects used at CEA, this presentation will focus on Visit, VTK and Paraview. In the first part we will address specific issues encountered when deploying VisIt and Paraview in a multi-site supercomputing facility for end-users. Several examples will be given on how such tools can be adapted to take advantage of a parallel setting to explore large multi-block dataset or perform remote visualization on material interface reconstructions of billions of cells. Then, the specific challenges faced to deliver Paraview’s Catalyst capabilities to end-users will be discussed. In the second part, we will describe how CEA contributes to open source visualization software and associated software development strategy by emphasizing on two recent development projects. The first is an integrated simulation workbench providing plugins for every step required to achieve numerical simulation independently on a local or a remote computer. Embedded in an Eclipse RCP environment, VTK views allow the users to perform data input using interaction or mesh preview before running the simulation code. Contributions to VTK have been made in order to smoothly integrate these technologies. The second details how recent developments at CEA have helped to visualize and to analyze results from ExaStamp, a parallel molecular dynamics simulation code dealing with molecular systems ranging from a few millions up to a billion atoms. These developments include a GPU intensive rendering method specialized for atoms and specific parallel algorithms to process molecular data sets.
