In Situ Data Management at DOE Workshop and SIAM CSE

​As CFD datasets get larger and unsteady computation becomes more common, file I/O is an increasing bottleneck. Methods that write post-processing extracts directly from solvers as they are running have proven to be a solution to this problem. Intelligent Light has long advocated for this approach and recently we were asked to participate in activities to advance the state of the art in this area.

In January, I participated in the DOE's "In Situ Data Management (ISDM)" workshop which focused on defining areas for research intended to ease the analysis and understanding of massive simulations enabled by exa-scale computing. A workshop report is forthcoming.

In February, I was invited to present at a mini-symposium at the SIAM CSE 2019 meeting aimed at avoiding the big data problem through in situ techniques.
