Foil 17 HLA/RTI and Coarse Grain Technologies II

From Object Models:Computing - Web Based Education and Training - Collaboration Seminar at Los Alamos -- 31 March 99. by Geoffrey C. Fox


Coarse Grain Entities can be time synchronized simulations and use MPI(HPF?) at either middle or back end tier or as in DMSO simulations a federate running a custom discrete event simulation
Use DMSO Object model HLA to specify object structure of jobs and systems at middle tier level
A HLA Federation could be the set of all jobs to be run on a particular site
  • We can classify both jobs and computers as separate federations
A HLA Federate could be a job consisting of multiple possibly shared objects
Use DMSO Runtime Infrastructure RTI to implement dynamic management
  • As RTI already incorporates time management as a service, it can be basis of powerful commodity resource management at level of linked coarse grain objects
