创建共享内存—shmget() 进程通过调用shmget(Shared Memory GET,获取共享内存)来分配一个共享内存块。 int shmget(key_t key ,int size,int shmflg) 1. 返回值:如果成功,返回共享内存表示符shmid,如果失败,返回-1。 参数1:key—标识共享内存块的键值 进程通过指定key值来获取对共享内存的访问。但是,其他进程都...

警告: 将 segment_size() 设置得接近或小于数据大小存在很高的数据丢失风险,因为写操作可能会在单次发送操作中覆盖缓冲区。这意味着,如果缓冲区不够大,新的数据将覆盖之前的数据,从而导致信息丢失。 总结 这些成员变量和相关设置允许用户灵活地配置共享内存传输特性,以适应不同应用场景下对性能和可靠性的需求。同时,...

嗯FlashAttention 就是适用于GPU极小的 片上存储(shared memory)SRAM作为cache,通过分块,一次性在GPU内部进行分块完成attention Reduce,elementwise subtract, softmax, Reduce, broadcast div 的操作,由于每部分mi reduce 结果只是局部reduce 需要用exp(局部reduce -全局reduce)进行误差补偿保证完整操作的正确性。这个操...
