Race Condition

A race condition occurs within a critical section when two or more tasks try to access and alter a shared resource simultaneously. As a consequence, the process changes to a state of inconsistency.

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…
Multithreading is more common than a scattering of unrelated processes running in the background. Explain.
When feasible, what are the upsides of prioritizing the I/O queue as the place where processes would be executed? If the I/O connection suddenly goes down, what do you expect to happen? How would this affect the fastest possible CPU burst rate? I'm not quite sure I get what you're getting at here.
Can the time it takes for distributed computing to switch between processes and threads be quantified?
Suppose that when run using a single thread, a particular program spends 20 seconds executing code that cannot be parallelized, and 280 seconds executing code that is highly parallelizable. Using Amdahl’s law, give an upper bound on the speedup (ratio of old to new execution time) that might be achieved for this program by exploiting parallel execution on a highly-parallel computer with thousands of processors/cores.
What are the drawbacks of using assembly language for non-specialist programming tasks? Is there ever a time when you'd recommend using assembly language?
Is it possible to put a time estimate on how long it takes for a distributed computing system to transition between processes or threads?
Answer the given question with a proper explanation and step-by-step solution. Operation Systems: In the simplest form possible.
As a simple model of a bus-based multiprocessor system without caching, suppose that one instruction in every four references memory, and that a memory reference occupies the bus for an entire instruction time. If the bus is busy, the requesting CPU is put into a FIFO queue. How much faster will a 64-CPU system run than a 1-CPU system?
On a computer system with one processor (CPU), and N (N> 1) processes present in the system, what is the maximum number of processes that can be in the Running, and in the Blocked states at any given time? Assume 5-state model for process states.
Is there a way to put a time estimate on how long it takes for a distributed computing system to transition between processes or threads?
Numerous multithreading algorithms are evaluated for uniprocessor and multiprocessor systems running on a variety of operating systems (Linux/Windows/Mac/Android, etc.). Is a comparison of CPU Scheduling Algorithms necessary?
