Hi guys:
John and I are starting to write a sparse engine -- for sparse storage of
our material-dependent fields. We think we have come up with an
optimization for our Eulerian code that should really make it scream. We
have been studying the IndirectionEngine example, which is very similar to
what we need.
Can you elaborate some more on the use and principle of this engine? Is it
like compressed brick?
Richard.
Unfortunately, the IndirectionEngine example problem, indirect_test1.cpp,
only demonstrates how to build the engine, not an array or a field. Could
someone please show us how to move forward with this example to building a
complete array and field version?
Unlike the IndirectionEngine example, we only need local communications
(not all-to-all) along with the same type of guard cell update found in a
normal field.
Any help will be greatly appreciated!
Jean, John, Don
