Course Description
Distributed systems is a popular and powerful computing paradigm. Their importance increases as networked computers become more common than free-standing ones, especially since many different types of computers can be found in networks.
In this course we will see the points of inherent difference and strength of distributed systems compared with sequential or strongly-coupled systems; consequently, we will also study the issues and problems that have to be addressed and solved efficiently for these differences to be taken advantage of, so that the system retains its strength and high potential.
In particular, we will address and study the following issues in distributed
systems:
a) Synchronization: Continuation (after the course "Distributed
Systems I") of the study of distributed clock-synchronization and
its uses in mutual exclusion; study about resource allocation in
general. Advance one step further, to see how to get solutions
without the need for clock synchronization (and hence of lower
cost in practice).
b) Replication: The advantages and costs of replicating data: the
potential improvement in response times and reliability, and the
extra communication costs involved in keeping data
consistent.
c) Fault-tolerant Agreement in Distributed Systems: (a very
special and significant problem, since it is a key issue in most
synchronization and coordination problems in distributed systems)
Study of the basic impossibility results and discuss their
implications; proceed with solutions and protocols for systems
with certain strengths and design structures.
d) Distributed Shared Memory: The difference between shared-memory-based
programming and message-passing-based programming; types of consistency;
write-update and write-invalidate protocols.
e) Resource allocation.
Course Evaluation
A team of at least three students representing the GU-CS students, the CTH International
Master's program students and the "local" CTH students needs to be
formed. The team's task is to:
- provide feedback from students
- take part in mid- and final-evaluation meetings
- write meeting minutes; and
- together with the teacher compile the final evaluation report.
