Description

云计算集群混部作业调度方法、装置、服务器及存储装置 技术领域
本申请涉及云计算技术领域,特别是涉及一种云计算集群混部作业调度方法、装置、服务器及存储装置。
背景技术
云计算服务因其高扩展性、按需服务以及极其廉价的特性而被广泛应用于数据中心服务平台,越来越多的企业和个人选择利用云计算平台运行应用程序。随之云集群中的服务类型越来越多样化,对作业调度的要求也越来越高。为了提升云计算集群整体的资源利用率,云数据中心相关人员开始逐步重视对物理主机的混合利用。
目前,提升云计算集群资源利用率主要从两个方面进行。一是负载特征分析与资源预测,该方法通过对负载的历史运行日志进行分析,采用服务器学习模型等进行预测下一时刻的资源消耗情况,从而进行合理的资源分配。该方式在一定程度上缩短了资源请求与实际资源消耗的差距,减少服务器资源超售的情况。二是集群中的混部策略的部署,主要是将实时型业务和计算型业务混部在同一台物理机中。但是,目前大部分的作业调度方案考虑的是单个层面,即资源层的资源需求或者作业本身的调度优先级,采用的方法有神经网络、蚁群算法等经典启发式算法,排队论等,或者是基于经典算法模型的改进策略,其忽略了混合部署时,不同类型的负载之间互相干扰而导致服务器集群性能下降的问题。

图1是本发明第一实施例的云计算集群混部作业调度方法的流程示意图。需注意的是,若有实质上相同的结果,本发明的方法并不以图1所示的流程顺序为限。如图1所示,该方法包括步骤:
步骤S1,分析预先获取的多种负载类型的历史运行日志数据,确认每种负载类型运行时所需的最大资源值。
需要说明的是,多种负载类型的历史运行日志数据需要预先进行采集,并且,历史运行日志数据包括CPU利用率、内存利用率、磁盘占用大小、网络I/O等属性值,采样频率可以设置为每隔60秒采样一次。
具体地,通过分析每种负载类型的历史运行日志数据,即可得到每种负载类型运行时所需的最大资源值,该资源值包括负载运行时所需的CPU、内存等资源。
步骤S2,基于最大资源值模拟将多种负载类型混合部署至服务器,并获取每种混合部署模式下硬件事件的发生频率。

步骤S3,基于硬件事件发生频率计算每种混合部署模式的推荐评分。
需要说明的是,每种混合部署模式的推荐评分的计算公式为:
Figure PCTCN2019125432-appb-000002
其中,T w1w2为w1、w2两种负载类型混合部署时的推荐评分,S HEM={IPC,BPM,LLCM……}(即硬件事件),w1、w2分别代表不同类型的负载,rate i表示w1、w2混合部署运行时w1的硬件事件发生频率与w1单独部署运行时的硬件事件发生频率的比值,w1单独部署运行时的硬件事件发生频率可提前获取,α i为预先设定的硬件事件的权重。
步骤S4,当接收到作业调度请求时,确认满足作业调度请求的所需资源。
步骤S5,筛选出符合所需资源的服务器列表,并从服务器列表中确认推荐评分最高的目标混合部署模式。
具体地,获取各个服务器的当前剩余的资源,再根据所需资源筛选出符合要求的服务器,组合成一个服务器列表,再根据作业调度请求和已经运行的负载确认服务器列表中推荐评分最高的目标混合部署模式。
步骤S6,根据目标混合部署模式对作业调度请求进行系统调度。
本实施例通过分析不同负载类型混合部署时,各硬件事件发生特征,从而得到不同负载类型混合部署形成的混合部署模式的推荐评分,在接接收到作业调度请求时,确认作业调度请求所需资源,再从满足所需资源的服务器中筛选出作业调度请求与其他负载混合部署时推荐评分最高的混合部署模式,并根据此混合部署模式对作业调度请求进行系统调度,其综合考虑了资源和不同负载之间的干扰情况两个方面,避免了因负载之间互相干扰而导致服务器性能下降的问题,提升云服务器整体资源利用率。
将本发明的云计算集群混部作业调度方法应用于云计算集群混部作业调度装置的过程中,还存在新的类型的负载进入的情况,因此,上述实施例的基础上,其他实施例中,如图2所示,步骤S2之前,还包括:

在本实施例中,当出现新的负载类型时,对该新出现的负载类型与已有的 负载类型进行相似性分析,从而确认与该新的负载类型最接近的负载类型,进而对新的负载类型的所需的最大资源值作出预测,再根据预测的最大资源值将新的负载类型和已有的负载类型模拟混合部署的场景,从而提高该本发明实施例提供的云计算集群混部作业调度方法的泛用性。
将本发明的云计算集群混部作业调度方法应用于云计算集群混部作业调度装置的过程中,还需要判断是否有服务器满足作业调度请求所需资源,因此,上述实施例的基础上,其他实施例中,如图3所示,步骤S4之后,还包括:
步骤S20,判断是否有服务器满足作业调度请求的所需资源。若有,则执行步骤S5~步骤S6;若无,则执行步骤21。

将本发明的云计算集群混部作业调度方法应用于云计算集群混部作业调度装置的过程中,还需要对作业调度请求设置优先级,因此,上述实施例的基础上,其他实施例中,如图4所示,步骤S4之后,还包括:
步骤S30,初始化作业调度请求的优先级。
具体地,初始化作业调度请求的优先级P=M,其中,M为预先设定的优先级阈值,即允许的最大重复调度次数。
步骤S31,判断优先级是否为零。若优先级为零,执行步骤S32;若优先级不为零,则执行步骤S5~步骤S6。
步骤S32,直接执行系统调度操作。
本实施例中,根据作业调度请求的优先级确认是否需要优先对作业调度请求进行处理。
进一步的,在上述实施例的基础上,步骤S5包括:
步骤S33,判断是否存在符合所需资源的服务器。若存在,则执行步骤S34~步骤S35;若不存在,则将优先级减一,并再次执行步骤S31及后续步骤。
步骤S34,筛选出符合所需资源的服务器,得到服务器列表。
步骤S35,判断服务器列表中是否存在符合作业调度请求与多种负载类型的混合部署模式。若存在,则执行步骤S36;若不存在,则将优先级减一,并再次执行步骤S31及后续步骤。
步骤S36,将符合作业调度请求与多种负载类型的混合部署模式中推荐评分最高的混合部署模式作为目标混合部署模式。
本实施例中,为了避免作业调度请求等待的时间过长,每判定一次不存在符合所需资源的服务器或服务器列表中不存在符合作业调度请求与多种负载类型的混合部署模式时,将作业调度请求的优先级减一,直至优先级降为零时,对该作业调度请求进行系统调度。
图5展示了本发明云计算集群混合部署作业调度装置的结构示意图。如图5所示,该云计算集群混合部署作业调度装置1包括分析模块10、模拟模块11、计算模块12、确认模块13、筛选模块14和调度模块15。

可选地,每种混合部署模式的推荐评分的计算公式为:
Figure PCTCN2019125432-appb-000003
其中,T w1w2为w1、w2两种负载类型混合部署时的推荐评分,S HEM={IPC,BPM,LLCM……},w1、w2分别代表不同类型的负载,rate i表示w1、w2混合部署运行时w1的硬件事件发生频率与w1单独部署运行时的硬件事件发生频率的比值,α i为预先设定的硬件事件的权重。
可选地,模拟模块11基于最大资源值模拟将多种负载类型混合部署至服务器的操作之前,还包括:当出现新的负载类型时,通过相似性分析确认与新的负载类型最接近的负载类型,以确认新的负载类型所需的最大资源值。
可选地,确认模块13确认满足作业调度请求的所需资源的操作之后,还包括判断是否有服务器满足作业调度请求的所需资源;若有,则筛选模块14和调度模块15执行后续操作;若无,则保持作业调度请求,并继续等待,直至有满足所需资源的服务器。
可选地,确认模块13确认满足作业调度请求的所需资源的操作之后,还包括初始化作业调度请求的优先级;判断优先级是否为零;若优先级为零,则直接执行系统调度操作;若优先级不为零,则筛选模块14和调度模块15执行后续操作;筛选模块14筛选出符合所需资源的服务器列表,并从服务器列表中确认推荐评分最高的目标混合部署模式的操作可以为:判断是否存在符合所需资源的服务器;若存在,则筛选出符合所需资源的服务器,得到服务器列表;若不存在,则将优先级减一,并再次执行判断优先级是否为零以及后续操作;在得到服务器列表之后,还包括:判断服务器列表中是否存在符合作业调度请求与多种负载类型的混合部署模式;若存在,则将符合作业调度请求与多种负载类型的混合部署模式中推荐评分最高的混合部署模式作为目标混合部署模式;若不存在,则将优先级减一,并再次执行判断优先级是否为零以及后续操作。
