Determine all cache accesses and the state of the data cache at any given time. From this you can determine any additional cycles from data cache misses. You must calculate the number of bits for the offset, index, and tag, determine the number of hits and misses, show the contents of the cache, and use the number of misses to determine any additional clock cycles required. The total clock cycles would be the total cycles for all iterations from Part 2 plus any additional memory access cycles from cache misses from Part 3.
The smallest and fastest part of a computer system's memory is the cache. The registers, which make up a very minor portion of the computer CPU, are quick storage components.
Why does the cache memory access time take less time than the main memory access time?Cache memory must be substantially smaller than main memory in order to be situated near to the CPU. As a result, it has less room for storage. Due to the increased performance of the more complicated chip, it is also more expensive than main memory.
What distinguishes Level 1 from Level 2 and Level 3 cache benefits?Since it is the smallest and nearest to the CPU, Level 1 (L1) cache memory is the quickest type. On the processor chip, Level 2 (L2) has a larger capacity but a slower speed. The computer that uses the L2 cache has the biggest capacity Level 3 (L3) cache memory.

You want to know which files are large files (at least 0.1MB) in your data directory, but you do not want to go through them one by one. So you decide to design a regular expression to help with this. Locate the rule under the p1 target in your Makefile. This rule uses the Is command to list the contents of the data directory in your current folder. The -I option produces the long listing for these contents, which includes their size in bytes. The output of this is command is then piped as input into grep command. The-E option for the grep command allows searching through this text with a regular expression. Replace the regular expression in this grep command to search for any 6 digit number. Since the size of these files are displayed in bytes, the smallest possible six digit number: 100000 corresponds to 0.1MB. When this regular expression is correct, running "make p1" should display the three large files that can be found within the provided data directory. Tip: Start by composing a regex that matches any single digit, and test this to make sure that it works as expected. If you encounter trouble with one specific way of matching single digits, like \d, then please try to find another way that works with grep - E. Once this is working, look for a way to extend this pattern so that it must be repeated exactly six times to be matched.
You must pipe the command's output through grep in order to utilize grep as a filter. " | " is the symbol for pipe.
Explain about the grep?The full line containing the matched string is displayed by default when using grep. To display only the matched pattern, change this setting. Using the -o option, we may instruct grep to show only the matching string. Using grep -n, output should be displayed together with the line number: To display the file's line number where the matching line was found.
Within collections of files, the grep command can look for a string. It outputs the name of the file, a colon, the line that matches the pattern, and the pattern when it discovers a pattern that matches in more than one file.
Instead of putting a filename at the end of a grep command, use an asterisk to search all files in the current directory.

i,j

i
and
j

[0,1,2,3,4]
, -
[0,2,3]

[0,1,2,3]

[2,4]
is nearly contiguous (from 2 to 4 , skipping 3 ), sum is 6 . - [3] is nearly contiguous (because it is contiguous from 3 to 3 ), sum is 3 . - [] is nearly contiguous (because it is contiguous from 1 to 0 ), sum is 0 . -
[0,2,4]
is not nearly contiguous (because you'd have to remove two elements). The sum of a nearly contiguous subarray is the sum of the included elements. Given int [] A, your task is to return the maximum sum of a nearly contiguous subarray. For example, on input
[10,9,−3,4,−100,−20,15,−5,9]
your algorithm should return 24 (corresponding to
i=

(d) What memoization structure(s) would you use? (e) What would the running time of your algorithm be (you do not have to write the code). Justify in 1-3 sentences.
(a) One possible recurrence to solve this problem is:
Let f(i, j) be the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before.
Then the recurrence can be written as:
f(i, j) = max(f(i, j-1), f(i, j-2) + A[j])
This recurrence calculates the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before by considering two possibilities:
The subarray does not include the element at index j. In this case, the maximum sum is the same as the maximum sum ending at index j-1.
The subarray includes the element at index j, but skips the element at index j-1. In this case, the maximum sum is the sum of the elements ending at index j-2 plus the element at index j.
(b) Another possible recurrence to solve this problem is:
Let g(i, j) be the maximum sum of a contiguous subarray ending at index j and starting at index i or before.
Then the recurrence can be written as:
g(i, j) = max(g(i, j-1) + A[j], A[j])
This recurrence calculates the maximum sum of a contiguous subarray ending at index j and starting at index i or before by considering two possibilities:
The maximum sum of the subarray includes the element at index j. In this case, the maximum sum is the sum of the maximum sum ending at index j-1 plus the element at index j.
The maximum sum of the subarray does not include the element at index j. In this case, the maximum sum is simply the element at index j.
(c) To calculate the final overall answer, we can input the values 0 and n-1 into both recurrences, where n is the length of the array A. This will give us the maximum sum of a nearly contiguous subarray that starts at the beginning of the array and ends at the end of the array.
(d) To implement these recurrences using memoization, we can use a two-dimensional array to store the calculated values of f and g. The array can be initialized with values of 0 for all indices, and then we can fill in the values starting from the bottom right corner and working our way towards the top left corner.
(e) The running time of this algorithm would be O(n^2), because we need to calculate the values of f and g for every possible pair of indices i and j. This requires O(n^2) time in the worst case.
True or False: A performance baseline is helpful in troubleshooting because it contains a backup of system critical data.
a. True
b. False
To make an effective backup plan, the very first step is to determine and identify the critical data. Hence the statement is true.
What is backup of system critical data?Organizations, individuals, and professionals mostly take backup regularly to avoid the risk of data loss.A backup plan is a plan that is created by the organizations or professionals to ensure that have backed up their essential and critical data if there is any risk of data loss. If data get loss then the organization may suffer. Because data is crucial for the organization or for professionals. If data get loss then the organization may need to minimize the downtime as much as possible. When organizations have their data backed up, then they would be in a position to restore the data that guaranty the ongoing business operations.Identify the critical data and determine the data importance: it is very first to identify the critical data for backup. In this step, data importance is determined, and the critical data are identified.To learn more about System Critical refer to:

Which of the following applications would be a viable reason to use write-only memory in a computer?
Question 20 options:
Using a linked list that can remove elements from the head as well as the tail
Acquiring user input from the keyboard
Preparing geometric shapes for use on a graphics card
None of the above
Note that of the following applications the one that would be a viable reason to use write-only memory in a computer is: "None of the above" (Option D)
What is write-only memory?Write-only memory, the inverse of read-only memory, started as a joking allusion to a memory device that could be recorded to but not read, as there appeared to be no practical purpose for a memory circuit that could not be retrieved.
ROM stores the instructions required for communication among various hardware components. As previously stated, it is required for the storage and functioning of the BIOS, but it may also be used for basic data management, to store software for basic utility tasks, and to read and write to embedded systems.
