Block Scheduling
According to recent estimates, 36 percent of Virginia’s regular public high schools operate on a 4x4 block schedule and 41 percent operate on an A/B alternating day schedule. This brief provides an overview of both of these models, highlights the potential benefits and challenges of block scheduling, and summarizes the research base. To date, studies examining the impact of block scheduling on ...
متن کاملScheduling Block-Cyclic Array Redistribution
This article is devoted to the run-time redistribution of arrays that are distributed in a blockcyclic fashion over a multidimensional processor grid. While previous studies have concentrated on e ciently generating the communication messages to be exchanged by the processors involved in the redistribution, we focus on the scheduling of those messages: how to organize the message exchanges into...

MIMO) enables single-layer transmission to several users who simultaneously share the same frequency allocation. In closed-loop spatial multiplexing (mode 4), one or more layers are transmitted using a precoder matrix that is selected from a predefi ned codebook. The precoder selections are typically based on channel measurements made by the UE. The precoders are applied to the layers transmitt...
