**MULTIPROCESSOR AND REALTIME SCHEDULING
Synchronization Granularity and Process
Grain size:-
Fine
Parallelism Inbent in single instruction stream
Grain size:-
very Course
Distributed Processing accross network nodes
Grain size:-
Medium
Parallel Processing
Grain size:-
Course
multiprocessing of concurrent processors
indipedent
multiple unrelated processes
Independent Parallelism
No emplicit synchronization among processes
each user is performing a particular application
multprocessor provides the same services
uesd in time sharing systems
Classification of Multiprocessor Systems
Highly Occupied MUtiprocessor
specialized processor that are contained by master processor
Functionally Specialized Processors
collection of realtively autonomous systems
Loosely Occupied /Distributed Multiprocessor
set of processor that share common main memory
Coarse And Course-Grained Parallelism
synchronization among process
good for coccurent processes running on multoprogramming uniprocessor
