Abstract:
The present invention relates to a temporal base method of mutual exclusion control of a shared resource. The invention will usually be implemented by a plurality of host computers sharing a shared resource where each host computer will read a reservation memory that is associated with the shared resource. Typically a first host computer will perform and initial read of the reservation memory and when the reservation memory indicates that the shared resource is available, the first host computer will write to the reservation memory. After a time delay, the host computer will read the reservation memory again to determine whether it has won access to the resource. The first host computer may determine that it has won access to the shared resource by checking that data in the reservation memory includes an identifier corresponding to the first host computer.
Abstract:
A data visualization system with the capability of viewing large amounts of data in a parallel coordinates system. Large amounts of data are displayed in parallel coordinates by grouping together data points by bins and representing grouped data with fewer graphical elements. The fewer graphical elements simplify the graphical representation of the data while still providing information about the density or volume of data occupying a particular space. Bins are determined for each axis. The volume of connections between a pair of neighboring pair of bins may be represented by modifying an aspect of the connection based on the volume.
Abstract:
A data visualization technique is provided with the capability of manipulating bins of data through an interactive graphical presentation of displayed data. When a histogram is generated from stored data, a user may interact directly with the histogram columns to change columns position, width and height. A user, for example, may click and drag a particular side of a bin to change the lower or upper limit of the bin, click and drag the top of a bin to change the size/height of the bin (i.e., number of data points/elements within the bin), or click and drag the center of the bin to move or reposition the bin. The techniques may be applied to other graphical representations of data as well, such as splat graphical displays of data.
Abstract:
An adapter retrieves graph data from one or more graph databases and adapts the data to be shown through a visualization tool. The adapter may be used to convert multiple formats of graph data into a format which is readable and useable by the visualization tool. The adapter module may make a connection with a graph database and query the database for particular graph data. Once retrieved, the stream of retrieved graph data may be used to populate a template in Java form. From the template, the visualization tool may provide a visualization of the retrieved data.
Abstract:
A system deploys visualization tools, business analytics software, and big data software in a multi-instance mode on a large, coherent shared memory many-core computing system. The single machine solution provides or high performance and scalability and may be implemented remotely as a large capacity server (i.e., in the cloud) or locally to a user. Most big data software running in a single instance mode has limitations in scalability when running on a many-core and large coherent shared memory system. A configuration and deployment technique using a multi-instance approach, which also includes visualization tools and business analytics software, maximizes system performance and resource utilization, reduces latency and provides scalability as needed, for end-user applications in the cloud.
Abstract:
A bootloader uses a TCP server to install and verify upgrades on a networked computing device such as a storage enclosure. A data management server client may connect to a bootloader on the storage enclosure using TCP. Once the connection is established, an upgrade image (upgrade data) can be provided directly to the bootloader and installed by the bootloader at the storage enclosure. The TCP server allows for the upgrade to be installed with minimal steps and a simple interface.
Abstract:
The front panel includes intelligence for controlling power, reset and power down functions for a storage enclosure having multiple servers, service processors, and enclosure management devices. The front panel may display information pertaining to system power state, disk activity, Ethernet activity, and other information. The front panel may implement sequencing rules for changes in power state. The front panel provides information for multiple servers and other devices through a single panel.
Abstract:
A high-performance-computer system includes a statistics accumulation apparatus configured to efficiently accumulate system performance data from a variety of system components, and periodically write such data to processor local memory for efficient subsequent software processing of the thus acquired data, thereby reducing the system hardware and software overhead needed for collection of such data as compared to prior art systems.
Abstract:
A primary data storage system is connected with a separate and external active archive storage system to consolidate data and allow active archive data to be managed based on primary storage system events. The primary data storage system may be managed and maintained by an external entity, and may include a manager module such as a resource manager. The active archive system may include several tiers of storage in a hierarchical storage system and logic for moving data between and among the tiers. As data processing milestones are completed or the state of data changes, in projects stored in the primary data storage system, task milestone or state change events are detected. Event detection can trigger data movement in the active archive solution. One or more software modules implementing the present invention may detect the events and trigger active archive operations based on the events.
Abstract:
In an embodiment, a micro ethernet connector includes an outer housing that has a recessed front end and a back end. The micro ethernet connector further includes an inner housing that is disposed within the recessed front end of the outer housing. The inner housing has an exposed end. The exposed end includes a recessed channel. The volume of the recessed channel is substantially equal to the volume of a correspondingly shaped protruding printed circuit board of a male micro ethernet connector. A plurality of spring-biased connectors are disposed within the recessed channel of the inner housing.
