My 2 cents.
For CFD: From math point of view: hybrid Eulerian-Lagrangian formulation,
hybrid numerical + analytic models, automatic differentiation, interval
arithmetic for sensitive analysis, machine learning (artificial
For HPC (that includes CFD): From sw implementation point of view:
asynchronous computation, symbolic computation, fault tolerant, DSLs, dynamic
and hierarchical data structures.
For HPC: From hw point of view: non coherent SOC (others called it relaxed
coherency), transaction based. The network holds the data, or the processing
happens in the network (eg. like packet inspection/enrichment). Very much in
the same way as air is held in the pipes for pneumatic infrastructures.
