Question

G=D+(A+C^2)*E/(D+B)^3 Rewrite the above formula in terms of doing concurrent processing using cobegin and coend to identify those instructions which can be processed concurrently.

Answer 1

Answer:

G=D+(A+C^2)*E/(D+B)^3

p1:C^2

p2:(D+B)^3

p3:A+p1

p4:E/p2

p5: D+p3+p4

COBEGIN

P1(p1,p2)

COEND

COBEGIN

P2(p3,p4)

COEND

execute p5

Explanation:

P1, P2 are parallel processes as they are independent of each other. And p5 together with P1, P2 forms the serial list of processes, and these must be executed serially.  And we need to run as mentioned above concurrent processes under cobegin and coend. Hence the above is the required list of processes and how they are processed. Concurrent processes are listed under cobegin and coend.
