Foil 35 Strategy for HPF

From GCF Talk U - Lewis/NASA 3/9/92 Mardi Gras Conference on Concurrent Computing in Physical Sciences -- February 18, 1993. by Geoffrey C. Fox


1 Program in an SPMD data parallel style
  • User writes code with (conceptually) a single thread of control and globally accessible data
2 Program is annotated with assertions giving information about desired data locality and/or distribution
3 Compiler generates code implementing data and work distribution from the user-written SPMD application
  • For MIMD - implementation is multi-threaded message passing with local data; generated synchronization and send/receive code
  • for SIMD - implementation is parallel code with communication optimized by complier placement of data
  • for vectors - implementation is vectorized code optimized for the vector units
  • for RISC - implementation is pipelined superscalar code with compiler generated cache management
