Please read everything carefully in advance. Please complete all of the questions in your own words. For text

answers you are expected to find quotes to support your ideas, If you use a quote from another source

$($including the notes or the textbook$)$ you must cite the source it came from. Failure to cite a source will result

in a $0$ for the entire assignment. This assignment contains many theory questions so I am expecting you to

include cited sources for most of your answers. You can use whichever citation style you like, and more

information on the citation styles can be found

here.

If you are asked to include a diagram it must be either drawn by hand and an image included or using a piece

everything must be typed and submitted digitally, handwritten and scanned answers besides images will be

an automatic $0.$ Please submit the files individually $($do not zip$)$ and text files must be submitted in the $.$docx

Q$1$: In your own words, explain why interrupts are not appropriate for implementing synchronization

primitives in multiprocessor systems. You must in ede a diagram as a part of your answer. Create and

use your own diagram and refer to it in your answer.

Q$2$: A multithreaded web server wishes to keep track of the number of requests it services $($known as

hits$).$ Consider the two following strategies to prevent a race condition on the variable hits. The first

strategy is to use a basic mutex lock when updating hits:

int hits;

mutex$\_$lock hit$\_$lock;

hit$\_$lock.acquire$()$;

hits$++$;

Whit$\_$lock.release$()$;

A second strategy is to use an atomic integer:

atomic$\_$t hits;

atomic$\_$inc$($shits$)$;

Explain which of these two strategies is more efficient $($make sure you explain WHY it is more

efficient$).$ You must include a diagram as a part of your answer. Create and use your own diagram and

refer to it in your answer.
