Foil 122 Spawning Tasks in HPF

From HPCC Software Technologies Fall 96 -- Overview and HPF Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 26 September 96. by Geoffrey C. Fox
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
