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…

Something in the Water Does Not Compute

Computational scientists at the Department of Energy’s Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2 femtosecond (one quadrillionth of a second) time step. The femtosecond is a timescale…
