Foil 28 Spawning Tasks in HPF

From CPS615-End of Numerical Integration and Very End of HPF Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 24 October 96. by Geoffrey C. Fox *
Secs 97.9
Task Parallelism is sort of supported in HPF but not clear to me that this is a great idea as better to keep sophisticated task parallelism outside HPF which is really only designed to support data parallelism
!HPF$ TASKING
  • !HPF$ ON HOME(p(1:8))
  • CALL foo(x,y)
  • !HPF$ ON HOME(p(9:16))
  • CALL bar(z)
!HPF$ END
This extends SPMD model with foo running on eight and bar on another processors
Note foo and bar are expected to contain data parallel statements which distribute execution using conventional HPF over 8 processors
