    Abstract: Provided is a system and method for directing group communication in a system environment that has a plurality of discrete application nodes networked with at least one discrete memory node, establishing a shared memory providing a passive message queue. A code library permits an application node member of a group to assemble a message selected from the group of send, join, leave, or read. The send, join and leave messages permit a first application node to add a message to the queue for all members of a group including the first application node at the time the message was added. The instruction set permitting the addition of the message is executed atomically.

    Abstract: An ergonomical pillow to be worn around the waist of a woman, supporting infant in a nursing position. The front pillow (10) has a front portion and adjacent left and right side portions. The front pillow (10) has an attaching mean (30a) attached to the left side and an attaching means (30b) attached right side of the front pillow (10). The nursing pillow (10) further comprises a webbing (45) with ends connected to the attaching means (30a) and (30b) A webbing (45) is laced around users back so that the ends of the webbing are over-passing the distal ends (13) and (13b) of the front pillow (10). The over-passing webbing is keeping distal end (13a) and (13b) down when a weight is placed on top of the front portion. The nursing pillow further comprises back support (32), supporting nursing woman's back against the seat.

    Abstract: Data storage devices of an enterprise system are tested to determine whether the enterprise system is optimally configured. Each data storage device is tested to determine whether it can satisfy a performance requirement for an assigned group of n workloads. A group of n inequalities are generated, and only up to n of the inequalities may be evaluated to determine whether the device satisfies the performance requirement for the assigned group of workloads. The inequalities are based on a phased, correlated model of I/O activity.

    Abstract: One embodiment of the present invention provides a method comprising assigning a first weight to a first consumer and a second weight to a second consumer. The method further comprises receiving at a first scheduler a request for service by a first resource to the first consumer; receiving at a second scheduler a request for service by a second resource to the first consumer; and receiving at the first scheduler a request for service by the first resource to the second consumer. The method further comprises scheduling, by the first and second schedulers, service from the first and second resources to the first and second consumers, wherein the scheduling maintains total service provided by the first and second resources to the first and second consumers in proportion to the respective weights of the first and second consumers without requiring the first and second schedulers to communicate with each other.

    Abstract: An embodiment of a method of estimating storage system reliability begins with a first step of modeling a storage system design in operation under a workload to determine location of retrieval points. The retrieval points provide sources for primary storage recovery for a plurality of failure scenarios. The method continues with a second step of finding a most recent retrieval point relative to a target recovery time that is available for recovery for a particular failure scenario. In a third step, a difference between the target recovery time and a retrieval point creation time for the most recent retrieval point is determined. The difference indicates a data loss time period.

    Abstract: The present invention provides techniques for assignment and layout of redundant data in data storage system. In one aspect, the data storage system stores a number M of replicas of the data. Nodes that have sufficient resources available to accommodate a requirement of data to be assigned to the system are identified. When the number of nodes is greater than M, the data is assigned to M randomly selected nodes from among those identified. The data to be assigned may include a group of data segments and when the number of nodes is less than M, the group is divided to form a group of data segments having a reduced requirement. Nodes are then identified that have sufficient resources available to accommodate the reduced requirement. In other aspects, techniques are providing for adding a new storage device node to a data storage system having a plurality of existing storage device nodes and for removing data from a storage device node in such a data storage system.
