IT Department of Synchrotron SOLEIL* is structured along of a team of software developers responsible for the development and maintenance of all software from hardware controls up to supervision applications. With a very heterogonous environment such as, several software languages, strongly coupled components and an increasing number of releases, it has become mandatory to standardize the entire development process through a 'Continuous Delivery approach'; making it easy to release and deploy on time at any time. We achieved our objectives by building up a Continuous Delivery system around two aspects, Deployment Pipeline** and DevOps***. A deployment pipeline is achievable by extensively automating all stages of the delivery process (the continuous integration of software, the binaries build and the integration tests). Another key point of Continuous Delivery is also a close collaboration between software developers and system administrators, often known as the DevOps movement. This paper details the feedbacks on this Continuous Delivery approach has been adopted, modifying daily development team life and give an overview of the future steps.

| WEPGF056 | Flyscan: a Fast and Multi-technique Data Acquisition Platform for the SOLEIL Beamlines | 826 |
|

| SOLEIL is continuously optimizing its 29 beamlines in order to provide its users with state of the art synchrotron radiation based experimental techniques. Among the topics addressed by the related transversal projects, the enhancement of the computing tools is identified as a high priority task. In this area, the aim is to optimize the beam time usage providing the users with a fast, simultaneous and multi-technique scanning platform. The concrete implementation of this general concept allows the users to acquire more data in the same amount of beam time. The present paper provides the reader with an overview of so call 'Flyscan' project currently under deployment at SOLEIL. It notably details a solution in which an unbounded number of distributed actuators and sensors share a common trigger clock and deliver their data into temporary files. The latter are immediately merged into common file(s) in order to make the whole experiment data available for on-line processing and visualization. Some application examples are also commented in order to illustrate the advantages of the Flyscan approach. | ||
