Dynamic Multithreading

An algorithm that executes a single instruction in a uniprocessor system is called a serial algorithm. In the case of a multiprocessor computer system, multiple instructions are executed in parallel. A multithreaded algorithm is an algorithm that enables multiple instances of the code to be executed concurrently.Multithreading is a concept that allows the CPU to execute threads independently while sharing similar resources. It is an important CPU feature that works on the process. Thread is a sequence of instructions that executes in parallel with other threads. Because of multithreading, multiple tasks can be performed within a single process.

Question

Consider a computer system with the following allocation status for four non-sharable resources, A, B, C, D at a certain time:
Allocation Max
Available
АВCD
АВCD
АВCD
PO
0101
8532
2301
3020
P2 3021
P1
3220
6022
At this instant, P0 requests (0, 2, 0, 1). The Operating System applies Banker's Algorithm to decide whether or not to grant this request.
Mark all the correct statements below based on this scenario:
O Need (2) = 3001
The system is currently deadlocked.
Granting this request brings the system to a safe state.
First row of Allocation matrix becomes 0302.
O Need (0) = 8230
Available vector becomes 2100.
O Need (1) = 0200

Suppose that an operating system supports two kinds of sequential processes: high-priority interactive processes, and low-priority non-interactive processes. The behavior of the high-priority processes is to alternate between periods of computation of duration Tc and periods of blocking (waiting for input) of duration Tb. The behavior of the low-priority processes is to compute constantly, with no blocking. The operating system’s scheduling policy is round-robin with a quantum q, where Tc < q. Scheduling decisions are made only when a quantum expires, or when the running process blocks. The scheduler selects a low-priority process to run only if no high-priority processes are ready. Suppose there is one high-priority process and one low-priority process in the system, and that both processes will run for a long time. For what fraction of the time does the low-priority process run?

An operating system uses the Banker's algorithm for deadlock avoidance when managing the allocation of three resource types X, Ý, and Z to three processes PO, P1, and P2. The table given below presents the current system state. There are 3 instances of type X, 2 instances of type Y and 2 instances of type Z still available. The system is currently in a safe state. Answer the following questions! Allocation Max X Y z X Y PO 0 1 8 4 3 (a) If PO requests 2 instances of Z during the P1 3 2 current state, can it be granted? Explain! (b) If P1 requests 2 instances of X during the P2 2 1 1 3 3 3 current state, can it be granted? Explain! CO
Given a set of jobs {J1, ... , Jn}, each job Ji = < ti, wi > has a required processing time ti and aweight wi. Design an efficient algorithm (pseudo code) to minimize the weighted sum of overall completion times ∑ni=1wiCi, where Ci is the completion time of job i. What is the time complexityof your algorithm? Note: You first need to briefly explain your ideas to solve the problem, e.g. what data structures are used, how the intermediate results are saved, which sorting strategy is used, and why the final results are correct;
