...considered as one clock tick. If the simple round robin is being used, the dispatcher picks the next process to run on every next clock tick. If 2 queues are being used, the sceduler runs processes with higher priority for 2 clock ticks and lower priority for one clock tick, alternating between queues. The driver simulates running of a process by generating a random reference to a page (you can choose FIFO or LRU to manage page replacements; you may incorporate a program from the first assignment). Program should print a) sizes, b) lifetimes, c) the moments of creation, d) the moments of completion of generated processes, e) reference strings for both processes, indicating page faults. Determine and submit the average turnaround time for each run. ## Deliverables 1) Complete a...

...replacement. The replaced entry is not written to disk. You can use any replacement policy for disk cache i.e. FCFS etc.,.In SSTFs, requests to the same track are to be processed in first-come first-served basis. You need to look at Disk::read() and Disk::write() to see how current disk schedulers work. Parameterize the scheduler types and (the size of the cache). Measure the cache hit ratios for FIFO+ and SSTF+. Measure the total seek times for the four modifications will be made to disk.C and disk.H only. Clearly mark all new and/or changed lines with any marker/commentsThe program should give output to convince that solution is correct.

...transfers control from one process to the other. Demonstrate the functionality of these by implementing a two process system that prints a random number of lines then yields. Be sure to implement an actual run queue using the FIFO that must be implmented in the next section. * Implement a muxtex that uses a separate FIFO to transfer processes that are waiting to get into the critical section from the run queue. Two functions *mutex_in and mutex_out* must be implemented along with a modified sample of the above test processes to demonstrate. This section must implement a FIFO of Process Control Blocks that will be used by both the pcreate/yield functions and the mutex_in/mutex_out functions. * Implement the Dining Philosophers' problem that hap...

Write two programs that simulate two versions of a paging memory management system - one based on FIFO algorithm, another one based on LRU (for LRU, you can use either system of counters associated with frames, or a stack). Make the following assumptions: a) the size of the internal memory is 40K, and it is divided into 10 page frames; b) the system loads and runs one process; the length of the process is 80K (thus, it is to be divided into 20 pages). Your driver program will be a loop running 40 times. On each run of the loop, it randomly generates a reference to a page in the process (a number in the range from 0 to 19) and makes sure that the referenced page gets a page frame. The driver will count and print out the total number of page faults; every time when a page fault occ...

MAS90 currently uses LAST COST to calculate the sales price on a "cost plus markup" item. For Instance: Inventory cost tiers show these item in inventory for item #1234 5 at 10.00 ea 10 at 10.50 ea Inventory valuation is $155.00 (correct). But when you sell 6 of these items (even if the system is set to FIFO) the sales order module calculates 6 at 10.50. I need it to calculate 3 at 10.00 and 3 at 10.50. We do not have the MAS90 code, only master developers do. We may be able to do this using the crystal report designer and a couple of user definable fields, But I need some help to see if it's posible.

Write a program to simulate the page replacement process in a virtual memory system. There is only one program. Assume the program consists of 1000 pages and that initially all pages are in backing store and that main memory is empty. Implement both the FIFO and LRU page replacement algorithms. Copy pages to backing store only if they have been modified. Input to the program will consist of the following information. No particular line fomat is assumed. Fields are to be separated by white space. -string= Replacement Algorithm: FIFO or LRU -int= Number of page frames -int= Trace: 0=no trace; 1=trace each paging action -int;char= Page reference: page number + R for read or W for write =... Repeat page references to end-of-file A trace entry is triggered each time a page is read...

The second function would be to update a section on the main page of the website by placing the some of the content. It would also be required to remove a line in order to maintain only the last 4 emails, a FIFO (first in first off basis) a small form would be created so that i can specify what content to look for and where to place the files I would also like a script that I could cut and past a report with both text and graphics and then have that report uploaded and stored on my website as well have a link created on an index page as well as have update a 4 title section on the main ...

Description In this project, you will be designing a cache simulator. The simulator must be able to handle the following characteristics: Cache Sizes: 1024, 2048, 4096, 8192, 16384 bytes Associativities: Direct Mapped, 2-way, 4-way, 8-way Replacement Policy: LRU, FIFO Block size: 16 bytes. The cache simulator should keep track of misses for each combination of size, associativity, and replacement policy. The input to your program will be a sequence of addresses. For each address, you should simulate a read from the cache. Therefore, given an address you would first check to see if it is contained in the cache. If it isn't, you would increment the number of misses and update the cache using the replacement policies. Assume the size of an address is 32 bits. You are provided with...

Coal trains arrive to an unloading facility with independent exponential interarrival times with mean 10 hours. If a train arrives and finds the system idle, the train is unloaded immediately. Unloading times for the train are independent and distributed uniformly between 3.5 and 4.5 hours. If a train arrives to a bust system, it joins a FIFO queue, The situation is complicated by what the railroad call "hogging out." In particular, a train crew can work for only 12 hours, and a train cannot be unloaded without a crew present. When a train arrives, the remaining crew time (out of 12 hours) is independent and distributed uniformly between 6 and 11 hours. When a crew's 12 hours expire, it leaves immediately and a replacement crew is called. The amount of time between wh...

...queues. Your library will create and perform several useful functions on queues. You will implement this library with a class. The name of your class MUST be queue The elements in the queue you will be creating are integers. A queue can contain any number integers, or none at all. The order of integers in the queue is important. Also, a queue can contain many instances of a number. The queues are FIFO queues. This means that the first elements in the queue are the first ones to be removed from the queue. Your library must follow these specifications: Allow user to create objects of type queue, both empty and nonempty. Format: queue data; /* Empty queue */ Format: queue data(A, 5); /* A is an int[], 5 is the number of elements in A to add to data in the same order they appear in t...

Implement a FIFO, First-In-First-Out, data structure, also known as a "queue." A queue satisfies these rules: 1) It stores data for us; if we have a queue object, say q, then when we want q to store a number, say 7.3, we "add" it to the queue with a call: (7.3). 7.3 is then placed into the queue q and then joins the other numbers that were on the queue. 2) Whenever we go to retreive data called "removing") from the queue, the number we get will always be the "oldest" item that we added. So if we call () 10 times after the first Add() above, and then we "remove" a number from the queue, the number returned by the Remove() method will the be 7.3. This also has the effect of removing 7.3 from the queue, so it is no longer there. If y...
