Question: For the solution to Too Much Milk suggested in the previous problem, each call to drinkMilkAndBuyIfNeeded() is atomic and holds the lock from the start to the end even if one roommate goes to the store. This solution is analogous to the roommate padlocking the Kitchen while going to the store, which seems a bit unrealistic. Implement a better solution to drinkMilkAndBuyIfNeeded () using both locks and condition variables. Since a roommate now needs to release the lock to the kitchen while going to the store, you will no longer acquire the lock at the start of this function and release it at the end. Instead, this function will call two helper-functions, each of which acquires/releases the lock. E.g.,
int
Kitchen : : drinkMilkAndBuyIfNeeded(){
int iShouldBuy = waitThenDrink();
if (iShouldBuy){
buyMilk();
}
In this function, waitThenDrink() should (if there is no milk) wait (using a condition variable) until there is milk, drink the milk, and if the milk is now gone, return a nonzero value to flag that the caller should buy milk. BuyMilk() should buy milk and then broadcast to let the waiting threads know that they can proceed. Again, test your code with varying numbers of threads.
Explain why a safety circuit or other EMERGENCY STOP device is important.
You will need to design an application that it will prompt a user for their hourly pay rate, their hours worked, and whether they are single, married, divorced, or widowed.
How would you design software to do this (Use a maximum of one to two paragraphs of 5-7 sentences each)?
Change the asynchronous-clear circuit to a synchronous-clear circuit in the register of Figure. The modified register will have a parallel-load capability and a synchronous-clear capability.
How many tasks real-time application contain In this particular real-time application, there are many tasks; each runs exact same code except with different data each time.
Merging is the mehood of combining two sorted lists into a single sorted list. In some cases, one list can be appended to the other, and the new list then can be sorted. Merging using this method, though, is not always the most efficient.
In any use of the pseudorandom numbers, whether for the encryption, simulation or the statistical design.
What is a ARP Request and ARP Reply?What is the broadcast.
As in our previous question, when the first request arrives in the disk request queue, the read/write head is at track 50, moving toward the outer (lower-numbered) tracks.
Using your learning materials and your own research, you will outline the principles of pipelining and explain the use of pipelining in computer architecture.
Recognize how to locate FSMO roles?
Your goal here is to use the simulators to understand these different types of memory caches. To do this, you need to run each type of simulator and document/explain what it is doing. For the three the cache simulators, you need to compare and con..
