Abstract: Data visualization is provided with the capability to interactively rotate data about a particular co-ordinate axis or other axis. Data to be visualized is accessed by a data visualization application. The accessed data may be displayed through an interface of the visualization application for a user. A user may rotate data about a particular axis of the coordinate system by providing a continuous input within a graphics portion of an interface. The input may be associated with the particular axis. The data displayed in the interface will rotate about the coordinate axis as the user drags the cursor.

Abstract: A pressure-activated server cooling system includes a server rack that houses one or more servers. The server rack has an interior plenum. A fan is coupled to the server rack that exhausts air from inside the plenum to outside the server rack. A differential pressure sensor collects pressure sensor data and a fan controller, which is operatively connected to the fan and the differential pressure sensor, activates the fan in response to the pressure sensor data. In some embodiments, the fan controller increases the speed of the fan when the pressure sensor data indicates greater than atmospheric pressure in the plenum.

Abstract: This innovation provides a method for a networked and replicated database management system (DBMS) using only one-sided remote direct memory access (RDMA). Replicated databases retain some access to the stored data in the face of server failure. In the prior state of the art, after the software in the DBMS on one of the servers acted on a client's request to update the database, it would contact the other replicas of the database and ensure that they had recorded the change, before responding to the client that the transaction was complete. This innovation describes a method whereby the database client directly interacts with each DBMS replica over the network using only RDMA to directly modify the stored data while maintaining the properties of database atomicity and consistency. This method reduces transactional latency by removing any need for the server DBMS software to respond to or forward requests for service.

Abstract: A system and method for remote rendering of computer graphics wherein user transactions are reliable and the transmission of rendered graphics is relatively fast. The invention is implemented in a client server context, where a computer graphics application and rendering resources are located at a server. A user controls the graphics application through a client machine connected to the server through a computer network. The user's commands are sent from the client to the server, while rendered computer graphics are transmitted from the server to a display at the client. Different transport protocols are used, depending on the requirements of a particular transmission. Data related to user interactions is transmitted using a relatively reliable transport protocol, such as TCP. Rendered subject graphics data is transmitted from the server to the client using a less reliable but faster transport protocol, such UDP.

Abstract: A high performance computing system is provided with an ASIC that communicates with another device in the system according to a protocol defined by the other device. The ASIC is coupled to a reconfigurable protocol table, in the form of a high speed content-addressable memory (“CAM”). The CAM includes instructions to control the execution of the protocol by the ASIC. The CAM may include instructions to control the ASIC in the event that unanticipated signals or other errors are encountered while executing the protocol. Internal ASIC state data may be routed to the CAM to permit the ASIC to generate a reasonable response to errors either in the design or fabrication of the ASIC or the device with which it is communicating.

Abstract: A system for deploying big data software in a multi-instance node. The optimal CPU memory and core configuration for a single instance database is determined. After determining an optimal core-memory ratio for a single instance execution, the software is deployed in multi-instance mode on single machine by applying the optimal core-memory ratio for each of the instances. The multi-instance database may then be deployed and data may be loaded in parallel for the instances.

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: High performance computing systems perform complex or data-intensive calculations using a large number of computing nodes and a shared memory. Disclosed methods and systems provide nodes having a special-purpose coprocessor to perform these calculations, along with a general-purpose processor to direct the calculations. Computational data transfer from the shared memory to the coprocessor incurs a data copying latency. To reduce this latency as experienced by the coprocessor, a complex computation is divided into work units, and one or more threads executing on the processor copy the work units from the shared memory to a local buffer memory of a computing node. By buffering these data for transfer from the local memory to coprocessor memory, and by ensuring that new data are copied while the coprocessor operates on older data, data copying latency is hidden from the coprocessor.

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 two part process is used for modifying records to be written and retrieved from tape devices. A record is appended with a cyclic redundancy check and a string of zeros. Submitting the entire record to tape drives which are logical block protection enabled will result in no change. For drives that are not LBP enabled, the string of zeros at the end of the record is removed. In addition to determining whether a drive is LBP compliant, a determination may be made as to whether a drive is a linear tape open drive from a particular manufacturer. Linear tape open drives may behave similarly as drives which may not be enabled with logical block protection.

Abstract: Data state rollover is performed based on data state snapshots and deltas. A series of snapshots is taken of the current data state, an original data state, and data states in between. Deltas are then generated between two sequential snapshots. This results in numerous deltas which represent the difference between consecutive snapshots. Once the deltas are acquired, the deltas may be stored along with the snapshot of the present data state. As such, previous data states may be rolled back to by determining the number of deltas to apply to the current data state to achieve the desired previous data state. In cases where the rollback or rollover fails, deltas may be played against the current data state to a point where the last known trusted and working data point existed.

The female member may include a central axis opening and a telescopically slidable outer sleeve. The outer sleeve may be spring-biased in a forward direction towards the central axis opening. A pull member may be coupled to the outer sleeve and may extend from the outer sleeve in a direction other than parallel to the radius of the outer sleeve.

Abstract: An algorithm for mapping memory and a method for using a high performance computing (“HPC”) system are disclosed. The algorithm takes into account the number of physical nodes in the HPC system, and the amount of memory in each node. Some of the nodes in the HPC system also include input/output (“I/O”) devices like graphics cards and non-volatile storage interfaces that have on-board memory; the algorithm also accounts for the number of such nodes and the amount of I/O memory they each contain. The algorithm maximizes certain parameters in priority order, including the number of mapped nodes, the number of mapped I/O nodes, the amount of mapped I/O memory, and the total amount of mapped memory.

Abstract: An adaptive router anticipates possible future congestion and enables selection of an alternative route before the congestion occurs, thereby avoiding the congestion. The adaptive router may use a primary route until it predicts congestion will occur. The adaptive router measures packet traffic volume, such as flit volume, on a primary network interface to anticipate the congestion. The adaptive router maintains a trailing sum of the number of flits handled by the primary network interface over a trailing time period. If the sum exceeds a threshold value, the adaptive router assumes the route will become congested, and the adaptive router enables considering routing future packets, or at least the current packet, over possible secondary routes.

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: Virtual storage pool creation is simplified by allowing a user to specify what devices to include in virtual storage pool by physical location. The virtual storage pool may be automatically generated based on the simplified user specifications. The user may specify the virtual pool configuration in a configuration file. A configuration application generates the virtual storage pool based on the configuration file. The configuration application utilizes the physical locations of block devices contained in the configuration file to generate the pool. As a result, virtual pool configuration and creation is automated, more efficient and is less error prone than previous methods that involve manually linking between physical device locations and computer generated names.

Abstract: A system reduces the impact of constrained bandwidth to long-term data storage without adding new data storage resources to the data center, typically by temporarily storing data on data storage devices that are contained within a desktop computer, a notebook computer, or other computing device. The invention stores lower priority data sets temporarily on data storage devices that are already purchased or expensed until lower priority data sets can be migrated to long-term data storage. The invention relieves the performance impact of congestion caused by slow communication interfaces, recording channels, and mechanical systems that move tape cartridges around. The invention may also be configured with security functions that restrict where or how certain data sets are stored temporarily.
