Consider the speedup gained by a multicore processor over a single processor. Use Amdahl’s law to calculate the speedup for the hypothetical scenarios below. Assume the total execution time of the program is 10 seconds. Assume N is the number of parallel processors. Assume 1-f and f are the execution time (fraction) involving code that is sequential and parallelized, respectively. Show your work and explain the size of the speedup (e.g., none, small, large, etc.). N=1, f=1. N=2, f=0.5 N=3,...

Write a C program for:
One technique for dealing with deadlock is called “detect and
recover.” In this scheme, some procedure is used
to identify when a deadlock occurs, and then another procedure
is used to deal with the blocked processes. One technique to
identify a deadlock is to maintain a resource graph that identifies
all processes, all resources, and the relationships between them
(that is, which processes exclusively own which resources, and
which processes are blocked waiting for which...
