– 1 – Fall 2015 EECS 338 Assignment 2 Due: Oct. 1st, 2015 G. Ozsoyoglu Concurrent Programming with Semaphores; 140 points (100 pts) 1. Priority-based Searchers/Inserters/Deleters Problem without starvation. Three types of processes, namely, searchers, inserters, and deleters share access to a singly linked list L, and perform search, insert, or delete operations, respectively. The list L does not have duplicate values. a) Searchers merely search the list L, and report success (i.e., item searched is in L) or no-success (i.e., item searched is not in L) to a log file. Hence they can execute concurrently with each other. b) Inserters add new items to the end of the list L, and report success (i.e., item is not in L, and successfully inserted into L) or no-success (i.e., item is already in L, and no insertion takes place) to a log file. Insertions must be mutually exclusive to preclude two inserters from inserting new items at about the same time. However, one insert can proceed in parallel with any number of searches. c) Deleters remove items from anywhere in the list, and report success (i.e., the item is found in L and deleted) or no-success (i.e., item is not in L, and could not be deleted) to a log file. At most one deleter can access the list L at a time, and the deletion must be mutually exclusive with searches and insertions. d) Initial start. Searcher, inserter, and deleter processes are initially launched as follows. A user process that needs a search/insertion/deletion operation to the list L first forks a process, and then, in the forked process, performs an execv into a searcher/ inserter/deleter process. e) Log maintenance. Upon start, each searcher/inserter/deleter writes to a log file, recording the time of insertion, process id, process type (i.e., searcher, inserter, or deleter), and the item that is being searched/inserted/deleted. f) Termination. Upon successful or unsuccessful completion, each searcher/inserter/deleter writes to the same log file, recording the time and the result of its execution. g) Priority-based service between three types. Searchers, inserters, and deleters perform their search, insert, delete operations, respectively, on a priority basis (not on a first-come-first-serve (FCFS) basis) between separate process types (i.e., searchers, inserters, deleters) as follows. Searchers search with the highest priority; inserters insert with the second highest priority (except that one inserter can proceed in parallel with any number of searchers), and deleters delete with the lowest priority. h) FCFS service within a single type. Processes of the same type are serviced FCFS. As an example, among multiple inserters, the order of insertions into L is FCFS. Similarly, among multiple deleters, the order of deletions into L is FCFS. Note that, among searchers, while the start of search among searchers is FCFS, due to concurrent searcher execution, the completions of multiple searchers may not be FCFS. i) Starvation avoidance. In addition to the above priority-based search/insert/delete operations, the following starvation-avoidance rule is enforced. o After 10 consecutive searchers search the list L, if there is at least one waiting inserter or deleter then newly arriving searchers are blocked until (a) all waiting inserters are first serviced FCFS, and, then (b) all waiting deleters are serviced FCFS. Then, both the standard priority-based service between process types and the FCFS service within a process type resume. You are to specify a semaphore-based algorithm to synchronize searcher, inserter and deleter processes. Note:  Explain your algorithm.  Make sure to state any assumptions you make in your solution.  Specify the initial states of your variables and semaphores.  Specify whether your semaphores are binary or nonbinary.  Do not bother specifying algorithms for sequential tasks: simply specify a well-defined function/procedure (i.e., one with well-defined input/output/functional specification). – 2 – (40 pts) 2. Four-of-a-Kind Problem is defined as follows.  There is a deck of 24 cards, split into 6 different kinds, 4 cards of each kind.  There are 4 players (i.e., processes) ??,0≤?≤3; each player can hold 4 cards.  Between each pair of adjacent (i.e., seated next to each other) players, there is a pile of cards.  The game begins by o someone dealing four cards to each player, and putting two cards on the pile between each pair of adjacent players, and o ?0 starting the game. If ?0 has four-of-a-kind, ?0 wins. Whoever gets four-of-a-kind first wins.  Players take turns to play clockwise. That is, ?0 plays, ?1 plays, ?2 plays, ?3 plays, ?0 plays, etc.  Each player behaves as follows. o So long as no one has won, keep playing. o If it is my turn and no one has won:  Check for Four-of-a-Kind. If yes, claim victory. Otherwise discard a card into the pile on the right; pick up a card from the pile on the left; and, check again: If Four-of-a-Kind, claim victory; otherwise revise turn so that the next player plays and wait for your turn.  There are no ties; when a player has claimed victory, all other players stop (when their turns to play come up). You are to specify a semaphore-based algorithm to the Four-of-a-Kind problem. Note:  Explain your algorithm.  Make sure to state any assumptions you make in your solution.  Specify the initial states of your variables and semaphores.  Specify whether your semaphores are binary or nonbinary.  Do not bother specifying algorithms for sequential tasks: simply specify a well-defined function/procedure (i.e., one with well-defined input/output/functional specification).
