多核图像灰度转换的程序，本程序主要做了以下几个任务：

（1）核0创建共享内存，将数据写入内存，然后通过Notify将内存地址发送给从核。

（2）从核（1至7核）接收核0的通知，打开内存地址，读取数据。-Multi core image grayscale conversion procedures, the procedures are mainly done the following tasks:

(1) the kernel 0 creates the shared memory, writes the data to the memory, and then sends the memory address to the slave by Notify.

(2)　the core (1 to 7 nuclear) to receive the notice of the nuclear 0, open the memory address, read data.
