The DMA ST1 seminar series features topics and tools around the full data lifecycle of the DMA communities.

The DMA ST1 seminar usually consists of a ~30 minute presentation, followed by a Q&A discussion session.

Attendance is open to all interested participants.

 

Data Reduction in Photon Science

Thomas White (DESY)

 

 

Abstract:  

We have implemented real-time data processing for serial crystallography experiments, with (in principle) no need for data persistence on disk.
We have increased the computational efficiency of CrystFEL to the point where less than one second is needed, on a single core, to fully process a 16 megapixel image.  Using the streaming interfaces of an Eiger detector, combined with the ASAP::O streaming platform developed at DESY, a small number of CPUs are needed to keep up with the 133 frames per second maximum full-frame readout rate.  I will discuss the advantages, potential disadvantages and general implications for how experiments might be performed in the future.
