Indexing external memory in reconfigurable computing fabric

The invention relates to indexing external memory in a reconfigurable computing fabric. Various examples relate to systems and methods in which a flow controller of a first synchronization flow may receive instructions to perform a first loop using the first synchronization flow. The flow controller may determine a first iteration index for a first iteration of the first loop. The flow controller may send a first synchronization message to a first computing element of the first synchronization flow to initiate a first synchronization flow thread for performing the first iteration of the first loop. The first synchronization message may include the iteration index. The first computing element is capable of performing an input/output operation at a first location of a first computing element memory indicated by the first iterative index. 本公开涉及在可重新配置计算结构中对外部存储器进行索引。多种实例涉及系统和方法，其中第一同步流的流控制器可以接收使用所述第一同步流执行第一循环的指令。所述流控制器可以确定所述第一循环的第一次迭代的第一迭代索引。所述流控制器可以向所述第一同步流的第一计算元件发送第一同步消息，以启动用于执行所述第一循环的所述第一次迭代的第一同步流线程。所述第一同步消息可以
