ECP task updates
Good job everyone with the FY19 deliverables!
Rountable notes
Matt noticed some performance abnormality. Matt wrote a filter to check to see if the ghost cells could be removed from a structured data set and remain structured. However, the algorithm that was identifying whether this was possible was running very slow. Matt made some changes to speed it up.
There are some issues with AMR data with lots of blocks. What are our plans for dealing with performance issues with lots of small partitions.
Hank has been getting some bad performance with particle advection on unstructured grids. This seems to be related to time to build locators.
Rob working on image connectivity algorithms. Also fixed invoker to support both mask and scatter.
Sujin looking into dashboard issues. Will be changing the VTK-c name to something else and other cleanup.
No meeting next week.
