云平台中的应用激发了在作业服务器约束和服务器异构性下有效负载平衡的研究。在本文中,我们研究二部图上的负载平衡,其中左节点对应于作业类型,右节点对应于服务器,每条边表示服务器可以服务的作业类型。因此,边代表局部性约束,即任意作业只能在包含某些数据和/或机器学习(ML)模型的服务器上提供。该系统中的服务器可以具有异构的服务速率。在此设置中,我们研究了名为加入最快的最短队列 (JFSQ) 和加入最快的空闲队列 (JFIQ) 的两种策略的性能,它们是加入最短队列和加入空闲队列的简单变体,其中关系被打破以支持最快的服务器。在“连通性”图条件下,我们证明当服务器数量趋于无穷大时,JFSQ 和 JFIQ 在平均响应时间上是渐近最优的。除了渐近最优性之外,我们还获得了有限大小系统的平均响应时间的上限。我们进一步表明,连通性条件可以通过具有相对稀疏连通性的随机二部图构造来满足。
Applications in cloud platforms motivate the study of efficient load balancing under job-server constraints and server heterogeneity. In this paper, we study load balancing on a bipartite graph where left nodes correspond to job types and right nodes correspond to servers, with each edge indicating that a job type can be served by a server. Thus edges represent locality constraints, i.e., an arbitrary job can only be served at servers which contain certain data and/or machine learning (ML) models. Servers in this system can have heterogeneous service rates. In this setting, we investigate the performance of two policies named Join-the-Fastest-of-the-Shortest-Queue (JFSQ) and Join-the-Fastest-of-the-Idle-Queue (JFIQ), which are simple variants of Join-the-Shortest-Queue and Join-the-Idle-Queue, where ties are broken in favor of the fastest servers. Under a "well-connected'' graph condition, we show that JFSQ and JFIQ are asymptotically optimal in the mean response time when the number of servers goes to infinity. In addition to asymptotic optimality, we also obtain upper bounds on the mean response time for finite-size systems. We further show that the well-connectedness condition can be satisfied by a random bipartite graph construction with relatively sparse connectivity.
