circulate this email on BE-1 and BE 2 groups : URGENT
Instructions for the CL-2 exam :-
1. All 9 assignments are compulsory...do not leave any assignment as option.
2. Changes cannot be given so everyone will have to do all assignments
3. Do not carry chits or programs on mass storage devices,copy of any kind is highly condemned.
4.We expect Bully algorithm to work on a single machine only,but we expect ring algorithm to work on both single and multiple machines.
Q: single machine meaning ?
A :single machine programs could be a single program simulated in the most simplest manner
and single machine programs could also mean multiple individual programs(separate PIDs) communicating over sockets
on a single machine/node(same IP).
Multiple machines : indeed different machines,different program IDs and different IPs
Also find herewith a list of practice oral questions ,
correct answers of which are expected.
