Abstract: In response to a stimulus indicating configuration of a node into a cluster of a plurality of nodes including the node, the node determines whether or not the node has a universally unique identifier (UUID), and if not, the node provides its own persistent self-assigned UUID. The node searches a cluster configuration database for a temporary identifier associated with the node. In response to the node locating the temporary identifier of the node in the cluster configuration database, the node writes its self-assigned UUID into the cluster configuration database and joins the cluster.

Abstract: Communication ability between nodes in a cluster-based computer system is tracked to inform applications executing on the nodes of the existence and quality of the endpoint-to-endpoint communications available between the nodes. Communications between a node and other nodes are tracked, and a database records the communication ability between the node and the other nodes for each link between the nodes. The tracking and recording are repeated at the other nodes. A registration by an application executing at a particular one of the nodes to receive notifications of changes in the communication ability with another node over a particular link (or in general) will cause notification of the application when the link status changes.

Abstract: A method of configuring a data processing system for facilitating network communications involves creating a primary logical partition (LPAR) in the data processing system, the LPAR configured to host a specified operating system. The method further includes creating a first virtual network adapter within the LPAR, associating the first virtual network adapter with a first network address, and binding the first virtual network adapter to the LPAR. The method additionally involves creating a first logical subpartition (LSPAR) within the LPAR, the first LSPAR configured to employ said specified operating system and no other. The method also includes creating a second virtual network adapter within the LPAR, associating the second virtual network adapter with a second network address, wherein the second network address is not an alias network address of the first network address, and binding the second virtual network adapter to the first LSPAR.

Abstract: An event notification system for distributed processing systems provides remote and local node event notification in systems that require local registration of an event consumer in order produce an event notifications. To provide notification of an event occurring on a remote node, either event consumers on all nodes in the cluster register locally to receive event notifications and specify that the event is a cluster event, in which case the nodes send notification of their locally-occurring events to all nodes, or remote registrations are accepted at nodes and if a local consumer for the event is not present, a listener thread registers as an event consumer. The listener thread sends the event notifications to the remote nodes registered as consumers for the event by observing communication between the event producer and the local consumer, or receiving the event notifications directly if there is no local consumer.

Abstract translation: 用于分布式处理系统的事件通知系统在需要本地注册事件消费者的系统中提供远程和本地节点事件通知，以便产生事件通知。 为了提供在远程节点上发生的事件的通知，集群中所有节点上的事件使用者本地注册以接收事件通知，并指定事件是集群事件，在这种情况下，节点发送其本地发生事件的通知 到所有节点或远程注册在节点处被接受，并且如果事件的本地消费者不存在，则侦听器线程注册为事件消费者。 监听器线程通过观察事件生成器和本地消费者之间的通信，或者如果没有本地消费者直接接收事件通知，则将事件通知发送到注册为事件消费者的远程节点。

Abstract: In one embodiment a method for migrating a workload from one processing resource to a second processing resource of a computing platform is disclosed. The method can include a command to migrate a workload that is processing and the process can be interrupted and some memory processes can be frozen in response to the migration command. An index table can be created that identifies memory locations that determined where the process was when it is interrupted. Table data, pinned page data, and non-private process data can be sent to the second processing resource. Contained in this data can be restart type data. The second resource or target resource can utilize this data to restart the process without the requirement of bulk data transfers providing an efficient migration process. Other embodiments are also disclosed.

Abstract: A speaker assembly mounted on a bracket extending from a ceiling comprises an enclosure that includes a bottom wall, side walls including opposing first and second side walls, a sleeve that receives a tubular member of the bracket, and an interior wall having a first segment that extends from the sleeve to the first side wall and a second segment that extends from the sleeve to the second side wall. The interior wall cooperates with the sleeve to divide the enclosure into two approximately equal sized compartments. Each of the speakers within the assembly either forms, or is mounted in or on, one of the side walls. A top plate is mounted on, and forms a top of, the enclosure and seals the two compartments, the top plate having an opening that is aligned with the sleeve when the top plate is mounted on the enclosure. A power unit and circuitry for the speakers are mounted on the top plate.

Abstract: Communication between clusters of processing nodes is initiated by designating a link layer address and a target node name in a remote cluster. The link layer address is transmitted to the target node via a regular network transmission. The link layer address is stored locally in each cluster and the nodes in each cluster are signaled that a configuration change has been made, so that gateway nodes in the clusters can obtain the link layer address to use for subsequent communications with the other cluster, such as event notifications of node status changes.
