Explanation of Solution

Importance of the optimization:

  • In NUMA (Non-Uniform Memory Architecture), a processor is capable of accessing its own memory in faster way when compared with a way it can access its own shared memory associated with another process.
  • It is because of the time taken in transferring the data between the processors.
  • Thus, if the data of a process resides in the local memory the process execution would be faster than the memory being non –local...

Dijkstra's Algorithm (part 1).  Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values.  Write down your final [correct] answer, as you‘ll need it for the next question.
