Final Project Parallel and Distributed Systems: Paradigms and Models (2018-19)

Autonomic_Farm_Pattern

The goal is to provide a farm pattern ensuring (best effort) a given service time leveraging on dynamic variation of the parallelism degree. The farm is instantiated and run by providing:

  • I. A collection of input tasks to be computed (of type Tin)

  • II. A function<Tout(Tin)> computing the single task

  • III. An expected service time TS goal

  • IV. An initial parallelism degree n w

During farm execution, autonomic farm management should increase or decrease the parallelism degree in such a way its service time is as close as possible to the expected service time TS goal . The pattern should be tested providing a collection of tasks such that the tasks in the initial, central and final part all require a different average time to be computed (e.g. 4L in the first part, L in the second part and 8L in the third part) and the task collection execution time is considerably longer than the time needed to reconfigure the farm.

To test Pthread and FastFlow implementation

Run the ./tests.sh

To run Pthread implementation:

cd ./Pthread make

./main n_tasks min_degree max_degree buffers_size ts_goal sma_window task_1 task_2 task_3

To run FF implementation:

--> Makefile has to be change accordly the fastflow folder location..

cd ./Fast_Flow make

./ff_main n_tasks min_degree max_degree ts_goal sma_window task_1 task_2 task_3
