This paper presents an experimental code generator that performs intra-block stack scheduling for a stack-based execution model. For small test programs, 91% to 100% of redundant local variable accesses were eliminated using this compiler. Compiled intra-block stack scheduling and hand-performed global stack scheduling show that significant opportunities exist to keep temporary variable values ...
During recent years, the Internet has witnessed rapid advancement in peer-to-peer (P2P) media streaming. In these applications, an important issue has been the block scheduling problem, which deals with how each node requests the media data blocks from its neighbors. In most streaming systems, peers are likely to have heterogeneous upload/download bandwidths, leading to the fact that different ...
The primary goal of processor scheduling is to assign tasks in a parallel program to processors, so as to minimize the execution time. Most existing approaches to processor scheduling for multiprocessors assume that the execution time of each task is xed and is independent of processor scheduling. In this paper, we argue that the execution time of a given task is not xed but is critically depen...
Recently, much attention has been paid on data-driven (or swarm-like) based live streaming systems due to its rapid growth in deployment over Internet. In such systems, nodes randomly select their neighbors to form an unstructured overlay mesh (gossip-style overlay construction) and then each node requests desired data blocks from its neighbors (block scheduling). To improve the performance, mo...
Scheduling is an enduring process where the existence of real time information frequently forces the review and modification of pre-established schedules. The real world is complex and complexity generally arises from uncertainty. From this prospective the concept of fuzziness is introduced in the field of scheduling. The present paper pertains to a bi-criterion in n-jobs, three machines fl...
To address the nation’s ongoing interest in student achievement, some researchers have focused on the effect of block scheduling—a model in which students take fewer classes for longer periods of time. Although block scheduling has demonstrated its viability in high schools, little research has explored its effect at the middle level. Because the middle level years are often marked by a decline...
Modern processors have multiple pipelined functional units and can issue more than one instruction per clock cycle. This puts great pressure on the instruction scheduling phase in a compiler to expose maximum instruction level parallelism. Basic blocks and superblocks are commonly used regions of code in a program for instruction scheduling. Instruction scheduling coupled with register allocati...
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...
In this paper, an efficient scheduling technique for multiuser MIMO downlink with block diagonalization precoding in millimeter waves channel is presented. The scheduling technique is based on employing hybrid DE/EPSO optimization method to maximize the sum rate capacity for selected number of users for outdoor cellular systems. The proposed scheduling scheme achieves almost similar capacity pe...
