Software cost estimation

In software engineering, cost estimation defines the calculation of the amount spent on software development and testing. This includes maintenance, managing, buying equipment, user requirement reviews, software, training, and servers. Many methods are developed to estimate the software project cost. Software cost estimation has a major impact on planning and managing a project. The software cost estimation has three estimates like project duration(time), effort(person-month), and cost(dollars).

Similar to, use the same approach to compute pi using mpi4py. As previously, the worker process identifies the region under the function 1+x2 for its associated portion. The number of processes is broadcast to all workers, who may then calculate their parts using the function calc pi. The root process then adds all of the results from the workers using the reduce operation and outputs the result. It is worth noting that in the reduction operation, we may indicate what to do with the obtained data.
1. Consider the following task set scheduled according to the rate monotonic assignment and answer the questions accordingly. T1-(1, 0.5), T2= (1.5, 0.4) (a) Is the schedule feasible? (b) Do these tasks fully utilize the processor (based on RM scheduling)? Show your answer. (c) (if the answer to (b) is “no",) Change the run time of the first task so that the resulting set will maximize the utilization of the processor under RM scheduling. (d) What is the maximum achievable utilization if the period for the second task was changed from 1.5 to 2 (and the run times could also be modified to achieve maximum utilization)?
