摘要

摘要

En 中文
在异构多云计算环境中,高效智能的任务调度因能源消耗、延迟最小化、服务级别协议(SLA)合规性以及主机利用率等相互冲突的目标而面临复杂挑战。本文提出了一种混合框架,该框架整合了用于时序工作负载预测的长短期记忆(LSTM)网络,以及用于多目标任务-主机分配的带记忆的大象群优化(EHOM)。该框架在OpenStack Yoga私有云中以容器化微服务形式实现,集成了Prometheus遥测、Kafka流、TensorFlow Serving用于LSTM预测,并通过OpenStack编排的Python基EHOM优化器。性能对比测试对象包括Trust-Aware Spring Swarm Optimization(TSSO)、Auto Clipped Double Deep Q-Learning(Auto-CDDQL)、基于自适应性花授粉的RSA(SA-FPRSA)、大象群狮优化(EHLO)以及基于马尔可夫的调度器。针对200–1000任务的工作负载实验结果表明,所提方法可降低12–22%的总能源消耗,减少8–15%的归一化延迟,提高2.5–5.3个百分点的事务截止时间满足率(DSR),同时始终将可用性和可靠性维持在97%以上。这些改进验证了所提框架在SLA敏感型多云计算环境中的鲁棒性、可扩展性及实时适用性。该系统通过闭环方式将LSTM预测与大EHOM分配器相连接。
