QUB Experience

QUB Experience

• Use of (automated program transformation tool
  (TAMPR) for source to source manipulation
• start with high-level algorithm definitions
  (specifications) as recursive functions
• output Fortran / (assembler-level) C / Java with
  library-based support for parallel execution
  (MPI, etc.).
• Transformation system is a programming-model to
  programming-model translation engine. Work has
  focused on developing a hierarchy of programming
  models
• single specification (functional style)
  multiple outputs (CSP, BSP, MPI, GrabAndGo,)
• reduces the effort on transformational
  development.
• Work has focused on shared memory
  multi-processors and closely coupled distributed
  machines.

QUB Contribution to CoreGRID

• GRID applications may be placed in two
  categories
• applications which require no (internal)
  architectural modification. The GRID middleware
  assigns resources appropriately to the
  application.
• applications which will benefit from
  architectural (and possibly dynamic) adjustment
  to allow execution using heterogeneous
  distributed resources.
• QUB proposes to extend its experience in the
  derivation of shared-memory parallel
  implementations from sequential (functional)
  specifications using automated transformation by
• targeting heterogeneous, remotely located
  resources
• including dynamic reconfiguration.
