Expert Solution & Answer
Chapter TG.3, Problem 1DQ
Explanation of Solution
Server farms: It is a set of system servers that are maintained by the organization in order to provide functionality of the server. It contains numerous computers that require huge amount of power supply.
Value of server farm on a large organization:
- The servers from server farm might provide idleness and fault tolerance that is, if a single system fails, then the application will be rolled over automatically to another system.
- Though server farm contains numerous servers, it requires large amount of:
- Power supply
- Air conditioning
- Generators for back-up
- Security
- Money for maintenance
- They should be placed closely to fiber-optic communication links.
Server virtualization: It is a method that follows software based partitions in order to create many virtual machines on a distinct physical server. This virtual machine allows to perform various applications on its own platform. It also increase the usage of server.
Value of server virtualization on a large organization:
- They mainly focus on the services that are provided by the technology.
- Though they are virtual machines, they work as a huge number of servers and it requires,
- Low cost
- Low energy,
- Minimum space
- Less cooling system
- Less maintenance

After playing our giving implementation, your task is to implement Dinning Philosophers
with semaphore in C, by including and
Your implementation will require creating five philosophers, each identified by a number
0.4. Each philosopher will run as a separate thread. Create threads using Pthreads
as discussed in the Lecture slides on Chapter 4 and Practice Lab on Threads.
Your solution needs to accomplish the following:
Implement in C (15 points)
1. dp1.c - You are to provide your solution to this assignment as a single C program
named 'dp1.c using semaphore. Explain in you code (as comments) that the dead
lock will happen or not. If there is a possible deadlock, you can simply solve the
deadlock by pick the fork in order like the first solution in our slides.
