M - algorithm corrections, C/C++ Programming

Assignment Help:

Of course it is C[i] = A[i] + B[i].It was a typing mistake,never mind. You just understand the concept.

27-1 b.

for grain-size=1

n=A.length

grain-size=1

r=n

for k=0 to n-1

spawn ADD-SUBARRAY(A,B,C,k+1,min((k+1),n)

)

sync

This will make n sub branches all to be executed in parallel and finally sync instruction will cause the flow of execution to be synchronized at that point.

27-1 C.

x1 is the constant to represent computational cost of spawning a new process. This step is executed (n/grain-size) number of times.
x2 is the constant to represent the computational cost of the addition operation. This step is executed (grain-size) number of times for each spawned preocess in parallel.

Hence total time for a parallel thread is x1(n/grain-size) + x2.(grainsize)
