| Description |
Funded by the U.S. Department of Energy (DOE), the LCLS is the world’s first hard X-ray free-electron laser. Its strobe-like pulses are just a few millionths of a billionth of a second long, and a billion times brighter than previous X-ray sources. Scientists use LCLS to take crisp pictures of atomic motions, watch chemical reactions unfold, probe the properties of materials and explore fundamental processes in living things. LCLS-II will provide a major jump in capability, moving from 120 pulses per second to 1 million pulses per second. This will enable researchers to perform experiments in a wide range of fields that are now impossible. A very performing and scalable storage infrastructure is needed to store DAQ files (XTC, HDF5), and have these data available to the analysis farm and data transfer nodes. At LCLS we chose Lustre as parallel HPC filesystem. In particular I implemented a new Lustre-over-ZFS solution for the DAQ fast feedback nodes, which replaces the older implementation based on Gluster. |
