Notes on homework 3

For question 4, where you have to write the RPC stubs, feel free to make reasonable simplifications to the performance of your implementation. For example, my sample solution makes the following assumptions:

• The queues only hold Integers, which simplifies converting the memory objects for transmission and reception.
• Each server machine serves only a single queue, so all clients connecting to that server get the same queue.
• The underlying PriorityQueue object for the server is passed as an argument to the server stub constructor.
• The address of the server to connect to is passed as an arugment to the client stub constructor.

• There is only ever one client running at a time (avoids a bunch of synchronization and threading issues at the server)

Your server stub will probably need to have a member function which actually implements the server loop. For example, the code that drives the server in my implementation does the following:

         PriorityQueue q = new PriorityQueue ();
         PQServerStub s = new PQServerStub (q);
         s.RunServer ();
