Answer this question: 2 copies of a code module are to be executed in parallel on identical processors organized into two communicating clusters A and B. Cluster A contains 8 processors and cluster B contains 4 processors. How many sets of processors can be used if cluster A has 2 failed processors and cluster B has 4 failed processors? __________

Answer #1

Total number of processes in cluster A and B

= 8+4

=12

The number of failed processes in cluster A and B

= 2+4

= 6

The cluster A and b executing 2 copies of code module

Then actually the unique number of processes are correctly working in the process is given by

12-6 = 6

Therefore, 6 processes are working in the deployment of 2 copies of code module.

which is

=

so, there are 15 processors that can be used

A certain program consists of three independent parts A, B and C that can execute in parallel on separate processors within a multiprocessor system. None of the parts can be further subdivided and each part must execute on a single processor. Part A requires 78 billion cycles to complete, part B requires 40 billion cycles to complete and part C requires 62 billion cycles. The program is executed on an SMP system with 4 identical processors all running at the...
