Third DOME face-to-face meeting: progress and plans

Submitter: Albert-Jan Boonstra, Ton Engbersen
Description: DOME is the research project in which ASTRON and IBM have joined forces to create new technology for handling the huge amounts of data that will be generated by the Square Kilometre Array (SKA). The project has been up and running for about a year now. On March 19-21, ASTRON hosted the third DOME face-to-face meeting. The picture shows 30 representatives from the DOME teams at ASTRON, IBM-NL, IBM-ZRL (Zurich Research Laboratories) and SKA-South Africa.

Progress: Team members were able to report good progress on many topics, such as:
  • retrospective analysis of LOFAR and extrapolation towards SKA;
  • data access patterns observed in LOFAR storage systems;
  • development of micro-server prototype;
  • testing of micro-pod optical data connector.

    Brainstorm: DOME research is spread across seven specific topics or work streams. One of those, compressive sampling, has recently been set in motion and was the subject of a productive brainstorm during our meeting. The main question for this work stream is: can we compact SKA's huge data rates (and therefore its processing requirements) by using clever algorithms, based on particular signal structures?

    SKA proposal: Just a week before our meeting, the SKA office issued its Request for Proposals (RfP). The RfP specifies the design work required for the SKA preconstruction phase. During the next few weeks, we will be assessing the current SKA baseline design. Our approach will be similar to the one we took on our retrospective analysis of LOFAR. The deadline for submitting our SKA proposal is June 10th. We will keep you posted.
