Title: EPICS Version 4 Development
Speaker: Andrew Johnson
Date: 29 January 2014 @ 11:30 AM
Location: 401 - B2100

EPICS Version 4 has been a formal international development project since 2011, with active members from 7 organizations spread across 4 US states and 3 European countries. This talk will discuss the main objectives and current state of the project, explain how and why the APS is involved, and suggest some advantages it could bring to the APS Accelerator and Beamline control systems.

Title: Experiment Control and Analysis for High-Resolution Tomography
Authors: Nicholas Schwarz, Faisal Khan, Ke Yue, John Hammonds, Francesco De Carlo
Date: 11 October 2013
Venue: ICALEPCS 2013

X-ray Computed Tomography (XCT) is a powerful technique for imaging 3D structures at the micro- and nano-levels. Recent upgrades to tomography beamlines at the APS have enabled imaging at resolutions up to 20nm at increased pixel counts and speeds. As detector resolution and speed increase, the amount of data that must be transferred and analyzed also increases. This coupled with growing experiment complexity drives the need for software to automate data acquisition and processing. We present an experiment control and data processing system for tomography beamlines that helps address this concern. The software, written in C++ using Qt, interfaces with EPICS for beamline control and provides live and offline data viewing, basic image manipulation features, and scan sequencing that coordinates EPICS enabled apparatus. Post acquisition, the software triggers a workflow pipeline, written using ActiveMQ, that transfers data from the detector computer to an analysis computer, and launches a reconstruction process. Experiment metadata and provenance information is stored along with raw and analyzed data in a single HDF5 file.

Title: Effective End-to-end Management of Data Acquisition and Analysis for X-ray Photon Correlation Spectroscopy
Authors: Faisal Khan, John Hammonds, Suresh Narayanan, Alec Sandy, Nicholas Schwarz
Date: 9 October 2013
Venue: ICALEPCS 2013

Low latency between data acquisition and analysis is of critical importance to any experiment. The combination of a faster parallel algorithm and a data pipeline for connecting disparate components (detectors, clusters, file formats) enabled us to greatly enhance the operational efficiency of the x-ray photon correlation spectroscopy experiment facility at the Advanced Photon Source. The improved workflow starts with raw data (120 MB/s) streaming directly from the detector camera, through an on-the-fly discriminator implemented in firmware to Hadoop’s distributed file system in a structured HDF5 data format. The user then triggers the MapReduce-based parallel analysis. For effective bookkeeping and data management, the provenance information and reduced results are added to the original HDF5 file. Finally, the data pipeline triggers user-specific software for visualizing the data. The whole process is completed shortly after data acquisition – a significant improvement of operation over the previous setup. The faster turnaround time helps scientists to make near real-time adjustments to the experiments.

Title: Not Dead Yet: Recent Enhancements and Future Plans for EPICS Version 3
Authors: Andrew Johnson, Janet Anderson, Michael Davidsaver, Ralph Lange
Date: 7 October 2013
Venue: ICALEPCS 2013

The EPICS Version 4 development effort* is not planning to replace the current Version 3 IOC Database or its use of the Channel Access network protocol in the near future. Interoperability is a key aim of the V4 development, which is building upon the older IOC implementation. EPICS V3 continues to gain new features and functionality on its Version 3.15 development branch, while the Version 3.14 stable branch has been accumulating minor tweaks, bug fixes, and support for new and updated operating systems. This paper describes the main enhancements provided by recent and upcoming releases of EPICS Version 3 for control system applications.

Title: Highlights from the 2013 Spring EPICS Collaboration Meeting
Speaker: Andrew Johnson
Date: 12 June 2013 @ 11 AM
Location: 401 - A1100

The EPICS Collaboration Meeting this May was hosted jointly by the Diamond Light Source and the ISIS Spallation Neutron Source, and was held at their Harwell campus in Oxfordshire, England. Andrew Johnson will present the highlights from a selection of the talks given at that meeting, including an update on the current state of the EPICS V4 developments.


Title: Driving Discovery: Visualization, Data Management, and Workflow Techniques
Organizers: Nicholas Schwarz (APS), Siwei Wang (MCS), Ian McNulty (CNM), and C.D. Phatak (EMC)
Date: 7 May 2013
Location: 401 - A5000

The great richness of data collected at the APS, CNM, and EMC plays critical roles in scientific exploration. As an example, imaging and microscopy experiments are adding dynamics and spectroscopic information to tomography. However, methods for understanding data have not kept pace; there is no “Moore’s law” scaling that applies to by-hand examination of data. Manual management and analysis of data is too time consuming and cumbersome for large, complex datasets. State-of-the-art mathematics and computer science tools will help automate the understanding process for large datasets. Only then will scientific understanding be able to fully benefit from the coming deluge of data.

This workshop is organized to discuss the state of the art and future potential of advanced optimization, visualization, data management, and workflow techniques for Argonne’s user facilities. It brings together experts in optimization, computer vision, visualization and data management alongside user scientists to discuss current and future applications. The goal is to elaborate on how users can benefit from these techniques to enable new scientific discovery.

Title: The ScanOcean Area Detector Viewer: Current Progress and Future Plans
Speaker: Nicholas Schwarz
Date: 16 January 2013 @ Noon
Location: 401 - A1100

ScanOcean is a general-purpose control and playback user interface application for Area Detector. It’s modeled after user interfaces often found on commercial microscopes and image acquisition systems. ScanOcean’s features include the ability to set up and monitor acquisition parameters for continuous playback and fixed-length recording, an interactive color and intensity levels adjustment tool, and a live histogram display. It uses Area Detector’s HDF5 file writer plug-in for storing acquired images, and provides users with a multi-window interface for simultaneously viewing live acquisition data and saved datasets. ScanOcean is written in C++ and uses Qt extensively. This presentation will discuss ScanOcean’s features and architecture as well as plans for future development.
