Answer:

hi your question lacks the necessary matrices attached to the answer is the complete question

1024 bytes

Explanation:

A) The minimum size of the cache to take advantage of blocked execution

 The minimum size of the cache is approximately 1 kilo bytes

There are 128 elements( 64 * 2 ) in the preceding simple implementation and this because there are two matrices and every matrix contains 64 elements .

note:  8 bytes is been occupied by every element therefore the minimum size of the cache to take advantage of blocked execution

= number of elements * number of bytes

= 128 * 8 = 1024 bytes ≈ 1 kilobytes

(10 points) 5.12. Discuss how the following pairs of scheduling criteria conflict in certain settings. a. CPU utilization (effic
Novosadov [1.4K]

Answer:

Check the explanation

Explanation:

  1. CPU utilization and response time: CPU utilization is amplified if the overheads that are connected with context switching or alternating are minimized. The context switching outlay can be reduced by performing context switches occasionally. This could on the other hand lead to increasing the response time for processes.
  2. The Average turnaround time and maximum waiting time: Average turnaround time is reduced by implementing the shortest or simple tasks first. Such a scheduling and arrangement strategy could nevertheless starve long-running tasks and in so doing boost their overall waiting time.
  3. I/O device utilization and CPU utilization: CPU utilization is maximized by executing a list of long-running CPU-bound tasks not including the performing context switches. This is maximized by setting up I/O-bound tasks as early as they become ready to run, thus sustaining the overheads of context switches.
