Problem 4There are two approaches for scheduling tasks on multiprocessor platform: the partitionedapproach and the global approach. The table below shows Ci (WCET) and Ti (period) for sixperiodic tasks to be scheduled on m = 3 processors.

Consider the following processes and their associated threads running on a multiprocessor system: Process Thread Arrival Time CPU Burst I/O Burst Total CPU Time X X1 0 4 2 11 X2 3 2 4 5 X3 3 2 4 5 Y Y1 5 6 2 14 Y2 5 3 5 7 Z Z1 7 1 1 6 Z2 7 3 2 10 Create a scheduling simulation for these threads on a system with two (2) processors using the First Come First Served (FCFS) algorithm. A thread may migrate from one processor to another if it returns from blocked waiting time and 1) the processor it was running on previously is occupied with other work; and 2) and the other processor is available to execute the thread. If both processors are available when a thread becomes unblocked, it will remain on the processor it was most recently running on. In this simulation, you will be managing a single ready queue that schedules all processes. When two processes arrive in the ready queue at…
3. Job Scheduling: Consider the problem of scheduling n jobs of known durations t1, t2, ..., tn, for execution by a single processor. The jobs can be executed in any order, one job at a time. You want to find a schedule that minimizes the total time spent by all the jobs in the system. (The time spent by one job in the system is the sum of the time spent by this job in waiting plus the time spent on its execution.) Design a greedy algorithm for this problem. Does the greedy algorithm always yield an optimal solution?

Quiz-1: Refer to Lecture-3 Module 1 swap (int* V, int k) { temp = V[k]; /* temp in $t0 */ V[k] = V[k+1]; V[k+1] = temp; } Write the swap() function using special registers required for accessing parameters passed to this function. Use “t” registers for any needed temporary registers.
A systolic array, which is a kind of array, is an example of a MISD machine. A systolic array is a pipeline network or "wavefront" of data processing units structured as a network. Because execution is triggered by the reception of fresh data, none of these components need the usage of a program counter. Each unit in a clocked systolic array computes in "lock-step," with each unit completing alternate calculation and communication phases in a single clock cycle.
Although most of your programming courses have focused on writing sequential programs, using lots of parallelism is the way to faster execution. We talked about two different basic execution models that can support massively-parallel execution: MIMD and SIMD. One of the easiest ways to get some speedup by parallel processing is to simultaneously execute multiple copies of the same sequential program with different input data. For example, if you need to convert thousands of images from color to black & white, simultaneously running 32 copies of a sequential program that converts a single image at a time could easily get you nearly 32X speedup over running one copy of the program at a time to process each image. Is that type of parallel execution essentially MIMD, SIMD, or equally suited to both MIMD and SIMD? Why?
An example of a MISD machine might be something like a systolic array, which is a kind of array. A pipeline network or "wavefront" of data processing units that is organised as a network might be referred to as a systolic array. Since the receipt of new data is what initiates execution, none of these components need the employment of a program counter in order to function properly. Each individual unit in a timed systolic array computes in "lock-step," meaning that within the course of a single clock cycle, each individual unit finishes alternating stages of computation and communication.
