Description
The Facility for Rare Isotope Beams (FRIB) is a United States Department of Energy Office of Science user facility focused on studying problems of national interest in low-energy nuclear physics. Real-time or near real-time analysis methods are critical tools for enabling FRIB science as new detectors and data acquisition technologies which allow for higher data rates and volumes are incorporated into laboratory systems. In addition, many experiments rely on computationally intensive analysis tasks where real-time processing on local computer systems is not feasible. The Energy Sciences Network (ESnet) provides the networking backbone for the ESnet-JLab FPGA Accelerated Transport (EJFAT) Load Balancers which, combined with the EJFAT Event Segmentation And Reassembly (E2SAR) software libraries, provide a platform for streaming data over UDP from FRIB to offsite locations such as the National Energy Research Scientific Computing Center (NERSC), where more computational resources are available to experimenters. An automated workflow was developed to stream data from files over ESnet from an FRIB experiment to NERSC using EJFAT/E2SAR, process digitized detector waveform traces at NERSC using a machine-learning inference framework, extract features of interest from the trace data, and send the results back to FRIB.
