哲学家进餐问题是荷兰学者Dijkstra 提出的经典问题之一,它是一个信号量机制问题的应用,在操作系统文化史上具有非常重要的地位。对该问题的剖析有助于学生深刻地理解计算机系统中的资源共享、进程同步、死锁等问题,并能熟练地应用信号量来解决生活中的控制流程,即将生活中的控制流程用形式化的方式表达出来。
假设有5个哲学家,他们花费一生中的时光思考和吃饭。这些哲学家共用一个圆桌,每个哲学家都有一把椅子。在桌子中央是一碗通心面,在桌子上放着5只筷子。(如图所示)当一个哲学家思考时,他与其他同事不交互。时而,哲学家会感到饥饿,并试图拿起与他相近的两只筷子(他与邻近左、右之间的筷子)。一个哲学家一次只能拿起一只筷子。显然,他不能从其他哲学家手里拿走筷子。当一个饥饿的哲学家同时有两只筷子时,他就不能不用释放他的筷子而自己吃了。当吃完后,他会放下两只筷子,并再次开始思考。
规定奇数号哲学家先拿他左边的筷子,然后再去拿右边的筷子;而偶数号哲学家则相反。按此规定,将是1、 2号哲学家竞争1号筷子;3、4号哲学家竞争3号筷子。即五位哲学家都先竞争奇数号筷子,获得后,再去竞争偶数号筷子,最后总会有一位哲学家能获得两只筷子而进餐。
