Title:  philosopher

Description:

An implementation of a solution to the Dining Philosophers problem
(a classic multi-thread synchronization problem).  This particular
implementation demonstrates the usage of nanokernel semaphores and
timers from multiple (6) fibers.

The philosopher always tries to get the lowest fork first (f1 then f2).
When done, he will give back the forks in the reverse order (f2 then f1).
If he gets two forks, he is EATING.  Otherwise, he is THINKING.

Each Philosopher will randomly alternate between the EATING and THINKING state.

--------------------------------------------------------------------------------

Building and Running Project:

This nanokernel project outputs to the console.  It can be built and executed
on QEMU as follows:

    make pristine
    make nanokernel.qemu

If executing on Simics, substitute 'simics' for 'qemu' in the command line.

--------------------------------------------------------------------------------

Sample Output:

Philosopher 0 EATING
Philosopher 1 THINKING
Philosopher 2 THINKING
Philosopher 3 EATING
Philosopher 4 THINKING
Philosopher 5 THINKING








Demo Description
----------------
An implementation of a solution to the Dining Philosophers problem
(a classic multi-thread synchronization problem).  This particular
implementation demonstrates the usage of multiple (6) fibers
of differing priorities and the nanokernel semaphores and timers.
