Abstract

In this paper, we study a typical scenario in research facilities. Instrumental data is generated by lab equipment such as microscopes, collected by researchers into USB devices, and analyzed in their own computers. In this scenario, an instrumental data management framework could store data in a institutionlevel storage infrastructure and allow to execute tasks to analyze this data in some available processing nodes. This setup has the advantages of promoting reproducible research and the efficient usage of the expensive lab equipment (in addition to increasing researchers productivity). We detail the requirements for such a framework regarding the needs of our case study of the CEA, review existing solutions and recommend the choice of Galaxy. We then analyze the performance limitations of the proposed architecture, and point to the connection between centralized storage and the processing nodes as the critical point. We also conduct a performance evaluation over an experimental platform to observe the limitations encountered in practice. We finish by pointing issues that are not addressed by existing solutions, and are therefore future work perspectives for the research field.
