Distributed systems (Networked Services)
please show steps:
Assume a system with two processes (P1 and P2), and the symmetric RTT between P1 and P2 is 20ms.
At t=0: P2 issues T1
At t=10: P1 issues T2
-
In what order do the transactions execute?
-
When does T1 execute at P1?
-
When does T1 execute at P2?
-
When does T2 execute at P1?
-
When does T2 execute at P2?
Homework Answers
--> Given Totally ordered multicast.
One-way latency between P1 and P2 is 20ms
At t=0: P2 issues T1
At t=10: P1 issues T2
--> When does T1 execute at P1?
T1 execute at p1 at time t = 20, It takes 20ms to reach p1 from p2
--> When does T1 execute at P2?
T1 execute at p2 at time t = 0, It executes instantly after issued.
--> When does T2 execute at P1?
T2 execute at p1 at time t = 10, It executes instantly after issued.
--> When does T2 execute at P2?
T2 execute at p2 at time t = 30, It takes 20ms to reach p2 from p1 after t = 10.

Difference in final temperatures? Please show all steps
Two containers (call them A and B) with the same initial volume, V 31 L, hold the same amount of monatomic ideal gas, say helium, at the same initial temperature T = 301 K and the same initial pressure Pi 1 atm. Container A holds the gas at a constant volume and Container B holds the gas at a constant pressure If you add Q 5389 J of heat to both containers,...

Yancey Productions is a film studio that uses a job-order costing system. The company's direct materials consist of items such as costumes and props. Its direct labor includes each film's actors, directors, and extras. The company's overhead costs include items such as utilities, depreciation of equipment, senior management salaries, and wages of maintenance workers. Yancey applies its overhead cost to films based on direct labor-dollars. At the beginning of the year, Yancey made the following estimates: Direct...
