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 microkernel task groups,
|
|
Mutex APIs and timer drivers from multiple (6) tasks.
|
|
|
|
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
|
|
states.

Building and Running Project:
|
|
|
|
This microkernel project outputs to the console. It can be built and executed
|
|
on QEMU as follows:
|
|
|
|
make pristine
|
|
make microkernel.qemu
|
|
|
|
--------------------------------------------------------------------------------
|
|
|
|
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) tasks
|
|
of differing priorities and the nanokernel semaphores and timers.
