int pipe(int fildes[2]);/*其中fildes[0]为读而开,fildes[1]为写而开,fildes[1]的输出是fildes[0]的输入*/ 函数pipe在内核中创建一个管道,并分配两个文件描述符标识管道的两端,这两个文件描述符存储于fildes[0]和fildes[1]中。一般约定fildes[0]为输入端,进程向此文件描述符写入数据,fildes[1]描述管道...
Ascend C编程范式是一种流水线式的编程范式,把算子核内的处理程序,分成多个流水任务,通过队列(Queue)完成任务间通信和同步,并通过统一的内存管理模块(Pipe)管理任务间通信内存。流水编程范式应用了流水线并行计算方法。 若n=3,即待处理的数据被切分成3片,则上图中的流水任务运行起来的示意图如下,从运行图中可以看...

pipe 指定Pipe模式。此时探测报文经过MPLS域时,IP TTL只在Ingress和Egress分别减1,整个MPLS域被当作了一跳。 - -wtimeout 指定等待响应报文的超时时间。 当发送数据包到达某网关超时,则输出“ * ”。 如果网络质量不高且速度很慢,建议增加发送数据包的超时时间。
