Abstract: Methods and apparatuses for servicing parallel requests to an open hash table are disclosed. A memory is used for storing a plurality of sub-tables, and a processor coupled to the memory that receives the incoming request which includes a key value to perform a first action in a first sub-table, calculates a routing hash value associated with the key value using a hash function, determines an index for the routing hash value by calculating a modulo (N) function of the routing hash value, and appends the incoming request to a queue associated with the first sub-table, wherein N is a number of sub-tables associated with the processor, the index corresponds to the first sub-table, and the processor is operable to retrieve the incoming request from the queue to perform the first action.

Abstract: The present invention describes a computer network including a network membership manager. In particular, a group of nodes on a computer network are managed by a distributed membership manager. Nodes of the computer network contain membership managers that manage the interaction between the nodes. Management of the computer network includes propagating configuration data to the nodes, providing an election process for determining the master node within a group of nodes, and monitoring the health of each node so that a change in the configuration and/or management structure can be accommodated by the nodes of the network.

Abstract: A computer system program including an operating system and a plurality of system service modules generates a number of status messages representing selected milestone events while it is being loaded and run, including progress advisories and technical advisories. User-friendly icons are displayed on a display monitor in response to the progress advisories, indicating which milestone event is occurring and how much of the event has been completed. If there is a failure in loading the system program, a user can provide service personnel with an accurate evaluation of the system condition by reporting which icon was displayed last on the monitor. Technical advisories such as audit records which are not relevant to a user are stored as entries in a silent log for possible later use by service personnel.
