说明：  主从模式粗粒级并行算法C程序：这是我以前研究生期间编写的叠前地震成像C源码，通过调用mpi库函数实现分频并行计算，为了实现负载均衡，采用了主从模式，由主节点负责任务的分发。 若需进一步了解，可通过版主与我联系讨论。
(Master-slave model of coarse-grained parallel algorithm for C-level procedure: This is my previous post-graduate prepared during the pre-stack seismic imaging C source code, by calling the library function mpi realize frequency parallel computing, in order to realize load balancing, using a master-slave mode, by master node is responsible for the distribution of mission. For more information, can contact me through the moderator to discuss.)
