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 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.

Abstract: A gossiping scheme for sharing node status in a cluster of nodes provides a robust mechanism for determining node status within the cluster. Nodes transmit gossip messages to each other nodes, the gossip messages listing other nodes in the cluster that are operational. When a node does not receive a gossip message from a particular node within a predetermined time period, then the node transmits messages to the other nodes indicating that the particular node is down. However, if another node has received a packet from the particular node within the predetermined time period and receives the node down message, then the other node responds with a node alive message.

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 computer implemented method, computer program product, and system for creating a checkpoint of a stream. A stream checkpoint request to create the checkpoint of the stream is received, wherein the stream is used by a process as a communications path, and wherein the communications path is modified by a set of modules. In response to identifying the identity of each module in the set of modules, the identity of each module in the set of modules is stored in the checkpoint. In response to identifying an order of the set of modules, the order of the set of modules is stored in the checkpoint. In response to sending a stream checkpoint message to each module in the set of modules, module data is received from each module in the set of modules to form received module data. The received module data is stored in the checkpoint.

Abstract: A coupon creation, publication, and redemption system and method includes a business account module at a server configured to assign a deal creation power to a product or service provider accessing a website with a client, and a coupon generation module configured to generate a listing of a deal and a predetermined number of coupons associated with a deal. The coupon is published via the website. The provider's history of coupon generation is tracked. Coupon grabbing and redemption powers are assigned to a consumer. The consumer grabs the coupons via the website, and its history of coupon grabbing is tracked. When a sale consummated, the grabbed coupon is marked as redeemed, while both the consumer's and the provider's history of coupon redemption is updated. The consumer's grabbing power is transformed in accordance with at least one of the consumer's coupon grabbing and coupon redemption history. The deal provider's deal creation power is transformed in accordance with at least one of the provider's coupon generation and coupon redemption history.

Abstract: Disclosed is a computer implemented method to resume a process at an arrival machine that is in an identical state to a frozen process on a departure machine. The arrival machine receives checkpoint data for the process from the departure machine. It creates the process. It updates a page table, wherein the page table comprises a segment, page number, and offset corresponding to a page of the process available from a remote paging device, wherein the remote paging device is remote from the arrival machine. It resumes the process and responsively generates a page fault for the page. It looks up the page in the page table, responsive to the page fault. It determines whether the page is absent in the arrival machine. It transmits a page-in request to the departure machine, responsive to a determination that the page is absent. It receives the page from the departure machine.

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.
