Standing up the Nation’s Supercomputing Pipeline for Streaming Big Data in Real Time

Big science generates big data. But what happens when researchers produce more data than they can process? It’s actually becoming a problem for research facilities that generate so much data that only supercomputers can tackle the volume. To bridge the gap between experimental facilities and supercomputers, experts from SLAC National…
