整体式:单个 MLIR 通道完成整个工作,而 MLIR 中的先前缓存被拆分为驻留在不同的方言。在一次性缓存中,BufferizableOpInterface实现分布在不同的方言中。 一次分析全功能。In-place bufferization就地缓存决策是通过分析张量上的 SSA 使用定义链生成的。OP操作接口实现不仅提供从张量操作到 memref 的重写逻辑 ops,也是...
A worker is currently transporting multiple parts from the source to the buffer in one trip. I’d like to adjust the spacing between the parts, reducing the distance between them (see figure). The buffer has a capacity of 60, and the worker can carry 30 parts at a time. This means th...
无锁Ringbuffer实现的吞吐率还是会随着子线程数增加而降低,但是并不如基于mutex的Ringbuffer强烈。当使用2个子线程时,吞吐率为7394830 op/s;当使用全部32个子线程时,吞吐率为5800350 op/s。前者是后者的1.27倍。 利用Perf分析程序热点只能定位到特点在enqueue和dequeue函数,无法提供进一步的信息。因此使用Arm的top-dow...
