20080201657 | SCALABLE PROPERTY VIEWER FOR A MASSIVELY PARALLEL COMPUTER SYSTEM - A method and apparatus for a scalable property viewer for a massively parallel computer system. The property viewer includes a graphical user interface to allow the user to view different properties of the computer system with several different types of views. The different views provide the user with both logical and graphical representations of the properties being monitored and allows the user to link between a logical and physical view of the system. The GUI provides the user with a convenient way to view the elements of a large system and determine elements that are different. Different properties could be placed together in the same view with different colors to allow the user to see the interaction of multiple properties. | 08-21-2008 |
20080263386 | DYNAMICALLY REROUTING NODE TRAFFIC ON A MASSIVELY PARALLEL COMPUTER SYSTEM USING HINT BITS - A method and apparatus for dynamically rerouting node processes on the compute nodes of a massively parallel computer system using hint bits to route around failed nodes or congested networks without restarting applications executing on the system. When a node has a failure or there are indications that it may fail, the application software on the system is suspended while the data on the failed node is moved to a backup node. The torus network traffic is routed around the failed node and traffic for the failed node is rerouted to the backup node. The application can then resume operation without restarting from the beginning. | 10-23-2008 |
20080270852 | MULTI-DIRECTIONAL FAULT DETECTION SYSTEM - An apparatus, program product and method checks for nodal faults in a group of nodes comprising a center node and all adjacent nodes. The center node concurrently communicates with the immediately adjacent nodes in three dimensions. The communications are analyzed to determine a presence of a faulty node or connection. | 10-30-2008 |
20080288820 | MULTI-DIRECTIONAL FAULT DETECTION SYSTEM - An apparatus, program product and method checks for nodal faults in a group of nodes comprising a center node and all adjacent nodes. The center node concurrently communicates with the immediately adjacent nodes in three dimensions. The communications are analyzed to determine a presence of a faulty node or connection. | 11-20-2008 |
20080313506 | BISECTIONAL FAULT DETECTION SYSTEM - An apparatus and program product logically divide a group of nodes and causes node pairs comprising a node from each section to communicate. Results from the communications may be analyzed to determine performance characteristics, such as bandwidth and proper connectivity. | 12-18-2008 |
20080320329 | ROW FAULT DETECTION SYSTEM - An apparatus and program product check for nodal faults in a row of nodes by causing each node in the row to concurrently communicate with its adjacent neighbor nodes in the row. The communications are analyzed to determine a presence of a faulty node or connection. | 12-25-2008 |
20080320330 | ROW FAULT DETECTION SYSTEM - An apparatus, program product and method check for nodal faults in a row of nodes by causing each node in the row to concurrently communicate with its adjacent neighbor nodes in the row. The communications are analyzed to determine a presence of a faulty node or connection. | 12-25-2008 |
20090037376 | DATABASE RETRIEVAL WITH A UNIQUE KEY SEARCH ON A PARALLEL COMPUTER SYSTEM - An apparatus and method retrieves a database record from an in-memory database of a parallel computer system using a unique key. The parallel computer system performs a simultaneous search on each node of the computer system using the unique key and then utilizes a global combining network to combine the results from the searches of each node to efficiently and quickly search the entire database. | 02-05-2009 |
20090037377 | DATABASE RETRIEVAL WITH A NON-UNIQUE KEY ON A PARALLEL COMPUTER SYSTEM - An apparatus and method retrieves a database record from an in-memory database of a parallel computer system using a non-unique key. The parallel computer system performs a simultaneous search on each node of the computer system using the non-unique key and then utilizes a global combining network to combine the local results from the searches of each node to efficiently and quickly search the entire database. | 02-05-2009 |
20090044052 | CELL BOUNDARY FAULT DETECTION SYSTEM - An apparatus and program product determine a nodal fault along the boundary, or face, of a computing cell. Nodes on adjacent cell boundaries communicate with each other, and the communications are analyzed to determine if a node or connection is faulty. | 02-12-2009 |
20090187984 | DATASPACE PROTECTION UTILIZING VIRTUAL PRIVATE NETWORKS ON A MULTI-NODE COMPUTER SYSTEM - A method and apparatus provide data security on a parallel computer system using virtual private networks. An access setup mechanism sets up access control data in the nodes that describes which virtual networks are protected and what applications have access to the protected private networks. When an application accesses data on a protected virtual network, a network access mechanism determines the data is protected and intercepts the data access. The network access mechanism in the kernel may also execute a rule depending on the kind of access that was attempted to the virtual network. Authorized access to the private networks can be made via a system call to the access control mechanism in the kernel. The access control mechanism enforces policy decisions on which data can be distributed through the system via an access control list or other security policies. | 07-23-2009 |
20100318835 | BISECTIONAL FAULT DETECTION SYSTEM - An apparatus, program product and method logically divide a group of nodes and causes node pairs comprising a node from each section to communicate. Results from the communications may be analyzed to determine performance characteristics, such as bandwidth and proper connectivity. | 12-16-2010 |
