Applications
Traditionally, NASA, DoD, DoE labs and their contractors have been big iron users
- CFD
- Structural
- “Bomb Codes”
A huge early success was Shell Oil’s seismic modelling code developed by Don Heller -- parallelism that made money
IBM did circuit simulation on a custom SIMD
Many claims were made but actual working parallelism was rare in 80s
The ability to run legacy code,
dusty decks, can be significant
