-- Now Cray, Convex (HP), Digital, IBM have massively parallel computing systems and Silicon
|
Graphics is becoming a powerful force high performance computing vendors
-
- Several architectures but only one: Distributed memory MIMDmulticomputer is known to scale from one to very many processors.
|
Software is challenge and could prevent/delay hardware trend that suggests parallelism will be a mainline computer architecture
-
- We must get systems software correct- Simultaneously develop applications software in gradually improvingparallel programming environment
