tices in the LogicalPipelinedRegion.</p>
<p>If there are any all-to-all distribution patterns inside the region, the entire region can just be converted into one SchedulingPipelinedRegion directly. That&rsquo;s because for the all-to-all edge with the pipelined data exchange, all the regions connected to this edge must execute simultaneously, which means they are merged into one region. For the all-to-all edge with a blocking data exchange, it will introduce cyclic dependencies, as Fig. 5 shows. All the reg
