具体实施方法A)分区管理分区管理是组织、管理机群的一种有效方式。 DETAILED DESCRIPTION Method A) is a partition management partition management organization, an effective way to manage fleet. 采用分区,使分区相互独立,可以有效组织资源,是增强机群系统规模可扩展性的基础(见附图2),也为灵活管理机群、使用机群提供了便利。 Using partitions, the partitions are independent, can effectively organize resources, it is to enhance the cluster system can scale basis scalable (see Figure 2), but also for flexible management of fleet using fleet facilitated.

在机群系统中有一个关于节点分区的配置文件,名为pools(将每个分区称为一个节点池pool)。 A node has a configuration file in the partition cluster system, named Pools (each partition is called a node pool pool). 根据这个文件,机群系统组织分区、部署各个分区里的分区资源管理器和租借公告牌,并依据pools文件内容初始化它们的信息。 According to this document, the organization cluster system partitions, each partition to deploy partition Explorer and lease bulletin board, and initialize them based on file content pools of information. 通过手工修改这个文件或通过命令方式修改机群分区信息,可以灵活的组织分区,达到机群资源管理的灵活性;可以为分区增加各种属性以及权限,实现机群应用和管理的多样化。 Modify this file by hand or modify the cluster partition information by way of command, the partition can be flexible organization, fleet flexibility to achieve resource management; and can increase the variety of property rights for the partition, diversification and fleet management applications. pools文件格式如下,关键字与内容以冒号隔离。 pools file format is as follows, keywords and content colon isolation.

●Name:pool的名字,它必须是仅由大写字母(AZ)、小写字母(az)、数字(0-9)以及下划线(_)构成的字符串,其最大长度不超过常量MAXPOOlNAMELEN(最大分区名长度)。 ● Name: pool name, it must be only of uppercase letters (AZ), lowercase letters (az), numbers (0-9) and the underscore (_) character strings with a maximum length of no more than constant MAXPOOlNAMELEN (maximum partition name length).

●Size:pool的大小,即pool所含的节点数。 ● Size: pool size pool that is contained in the number of nodes. 注意:size大小必须与nodelist中节点个数相符。 Note: size nodelist size must match the number of nodes.

●Nodelist:pool的节点集,给出所有属于该pool的节点的节点名,以“,”分隔。 ● Nodelist: pool node set, is given the name of nodes belonging to all nodes in the pool to "," separated. 注意:同一个节点只能出现在一个分区中。 Note: The same node can only appear in one partition.

●Leaselist:可出借资源的节点列表。 ● Leaselist: List node lending resources. 注意:出借节点集必须是nodelist的子集。 Note: lend node set must be a subset of nodelist.

●RMD_name:本pool内资源管理器所在节点的主机名●RMD_port:分区管理器监听的端口号●Property:pool的属性,用户自己定义,为任意字符串●Users:给出有权限使用该pool的用户/组,或者没有权限使用该pool的用户/组。 ● RMD_name: host name in this resource pool where the manager node ● RMD_port: Partition Manager listening port number ● Property: pool attributes, user-defined, arbitrary string ● Users: have given permission to use the pool of user / group, or not have access to the pool of users / groups.

有权限的用户/组以如下形式描述:+|username|@groupname|{,username|,@groupname}没有权限的用户/组以如下形式描述:-|-username|-@groupname|{,-username|,-@groupname}其中:|:表示“或者”{...}:表示括号内的内容“重复0次或多次”+:(一个加号)表示所有的用户都有权限-:(一个减号)表示所有的用户都没有权限username:表示某个用户的登录名groupname:表示某个组的组名。 Authorized users / groups described in the following form: + | username | @groupname | {, username |, @ groupname} unprivileged user / group described in the following form: - | -username | - @ groupname | {, - username |, - @ groupname} where: |: means "or" {...}: Indicates content within the brackets "repeated zero or more times" + :( a plus sign) means that all users have rights - :( a minus sign) means that all users do not have permission username: indicates that a user's login name groupname: group name represents a group.

根据pools文件中分区资源管理器所在的节点名和监听的端口号远程部署分区;根据每个分区所管理的节点列表收集管理每个分区内所有节点的资源信息;根据每个分区的属性和使用权限对每个分区进行管理。 According to the partition node name pools file explorer and where the listening port number of the remote deployment of partition; according to the resource information for all nodes for each partition managed to collect a list of nodes to manage each partition; according to the attributes and permissions for each partition manages each partition. 根据pools文件启动和初始化租借公告牌,租借公告牌从leaselist域中获取租借节点信息。 According pools and initialization file to start the billboard lease, rent billboard node information acquired on loan from leaselist domain. 由此,一种机群系统资源管理的分区租借方法,其具体实施步骤如下:a)建立名为pools的分区信息文件;b)依据pools文件启动和初始化分区资源管理器;c)依据pools文件启动和初始化租借公告牌。 Accordingly, a method of partitioning rental fleet resource management system, the specific embodiment the steps of: a) establishing the partition information file named pools; b) a boot and initialization files based on pools partition resource manager; c) Start file based on pools and initialization rent billboard.

在本方法中,将负责分区中资源管理、权限管理以及可租界资源管理的程序称为分区资源管理器,它以后台服务进程的形态存在于系统中。 In this method, the partition will be responsible for resource management, rights management and a concession resource management program called Partition Explorer, which later form table service processes exist in the system. 它启动时依赖于pools文件,启动后,它的工作流程详见附图3以及附图3的说明。 It depends on the starting pools file, after starting, it is the workflow of Figure 3, and 3 refer to the accompanying drawings.

B)租借节点分区独立后,可能有些应用需要跨区使用资源,这时需要租借其它分区资源。 After B) loan node partition independence, some applications may require the use of resources cross, then need to lease other partitions resources. 一个节点分区就是一个节点池(pool)。 A node is a node partition pool (pool). 闲置池可以出借资源,资源短缺池可以租借资源。 Pool may lend idle resources, shortage of resources pool can be rented resources. 在本方法中,管理各个分区租借信息的程序是租借公告牌,它以一个后台服务进程的形态存在于系统中,它管理这各个分区可以出借资源的节点信息,初始化时从pools配置文件中获取最初信息,并在运行过程中动态动态刷新租借资源信息。 In this method, the Program Manager each partition lease information is on loan bulletin board, it is in the form of a background server process exists in the system, which manage each partition can lend resources node information, the initialization obtained from the pools configuration file initially information, and dynamically updated dynamically leased resource information during operation.

资源之间的租借在租借公告牌的帮助下由各自的分区资源管理器协商决定。 Lease negotiation between the resource is determined by the respective partition resource manager with the help of loan bulletin board. 当某个分区需要租借资源时,先向租借公告牌查询可出借资源的节点,然后向相应的分区资源管理器申请租借资源。 When a partition needs to rent resources, Xianxiang rent billboard query node lendable resources, then apply to the corresponding partition Explorer loan resources. 当申请者满足资源租借权限(用户权限、足够的可出借资源)时,分区资源管理器出借资源(见附图3)。 When the applicant to meet the resource lease rights (User rights can lend sufficient resources), the resource manager partition lend resources (see FIG. 3).

当租借资源的应用完成时,自动释放资源。 When the application is complete loan resources, automatically free up resources. 当出借资源的分区负载过重时,系统管理员可以查看本分区资源出借情况,通过停止应用运行或应用迁移的方法来回收资源。 When the lending resources of the partition overloaded, the system administrator can view this partition resources loan, the recovery of resources by stopping running applications or application migration methods.

本发明的一个优点是分区的方法能有效地管理资源,适应异构机群资源的多样性。 One advantage of the present invention is a method of partitioning can manage resources efficiently, adapt to the diversity of heterogeneous cluster resources. 可以使同构节点划在一个分区里进行管理,使机群资源管理条理化、清晰化。 You can make homogeneous nodes in a partition plan to manage the cluster resource management principled, clarity.

本发明的另一个优点是每个分区可以实现各自不同的管理策略,适应用户使用的多样性和灵活性。 Another advantage of the present invention may be implemented is to partition each respective different management policies, diversity and flexibility to adapt to the user. 还要,每个分区有不同的权限控制,更方便于用户的使用和管理。 Also, each partition has different access control, more convenient for users to use and manage.

本发明的又一个优点是分区租借资源的方法巧妙地解决了跨区使用资源的问题,使得节点分区后也有办法使节点资源联合成一个整体来使用。 A further advantage of the invention is a method of partitioning resources leased neatly solves the problem of cross-use of resources, so that the partition is also a way to make the node node resources to use united into a whole.
