Hi ,

for a project we want to use openPMD (openpmd.org) as storage format. Has 
anybody been working on a areaDetector plugin using openPMD?
In the end we want to use ADIOS2 (adios2.readthedocs.io/en/latest.html) to 
transport the data with high speed to a remote server for storage and 
processing. Remote server will be used because then the offline analysis can 
start immediately without waiting for the data to be copied from the iOC 
server to the compute node.

The task is to handle 64Mpx images from a CCD@16bit at 10Hz. As the camera has 
USB3.0 as interface for readout, it's clear that we have to use binning of 4 
or even 6 to get this frames per second.

If we would implement all the necesarry analysis code as plugins for 
areaDetector, what would be the maximum frame rate that can be reliably 
displayed in e.g. phoebus? And is there a difference between CA and pva 
protocol?

Regards,
