20090138750 | REDUNDANT 3-WIRE COMMUNICATION SYSTEM AND METHOD - A redundant communication system and method for providing data communication between a first computing node and a second computing node. A transmitter is provided as part of the first computing node. A receiver is provided as part of the second computing node. A first signal line carries a first data signal. The first signal line electrically couples the transmitter with the receiver. A second signal line carries a second data signal redundant to the first signal. The second signal line electrically couples the transmitter with the receiver. The receiver evaluates the first data signal to determine the presence of an error and the second node uses the second data signal if an error is detected in the first data signal. | 05-28-2009 |
20090327686 | Updating A Basic Input/Output System ('BIOS') Boot Block Security Module In Compute Nodes Of A Multinode Computer - Updating a BIOS boot block security module in a plurality of compute nodes of a multinode computer including, for each compute node in the multinode computer, upon powering on the compute node: determining whether a new image of security module is available; if a new image of the security module is available, commanding the reset control module of the compute node to block an attempt by the security module to propagate a reset signal on the scalability bus to other compute nodes in the multinode computer; updating to the new image of the security module; upon completion of the update, resetting the compute node including attempting to propagate a reset signal on the scalability bus to other compute nodes in the multinode computer; and blocking the attempt to propagate the reset signal on the salability bus. | 12-31-2009 |
20110010584 | Diagnosis of and Response to Failure at Reset in a Data Processing System - Detection of a reset failure in a multinode data processing system is provided by a diagnostic circuit in each of a plurality of the server nodes of the system. Each diagnostic circuit is coupled to a code fetch chain of its corresponding node. At reset, prior to a node processor retrieving startup code from the code fetch chain, the diagnostic circuit provides diagnostic signals to the code fetch chain. A problem in the code fetch chain is detected from a response to the diagnostic signals. When a problem is detected, a node failure status for the problem node may be signaled to the other nodes. The multinode system may be configured in response to signaled node failure status, such as by dropping failed nodes and replacing a failed primary node with a secondary node if necessary. | 01-13-2011 |
20130173958 | Extending Cache In A Multi-Processor Computer - Methods, apparatuses, and computer program products of extending cache in a multi-processor computer are provided. Embodiments include detecting, by a donor processor, nonuse of a donor processor's cache; broadcasting to one or more processors in the multi-processor computer, by the donor processor, a donor-ready message indicating the donor processor's cache is available for ownership transferment; receiving from a first requesting processor, by the donor processor, a first ownership-request message requesting ownership of the donor processor's cache by the first requesting processor; transmitting to the first requesting processor, by the donor processor, an ownership-grant message indicating an intention of the donor processor to transfer ownership of the donor processor's cache to the first requesting processor; and receiving from the first requesting processor, by the donor processor, an ownership-claim message indicating that the first requesting processor intends to claim ownership of the donor processor's cache. | 07-04-2013 |

20090099628 | FIBER OPTIC PHOTOTHERAPY DEVICES INCLUDING LED LIGHT SOURCES - Phototherapy devices for phototherapy treatment of a patient include a light emitter for emitting light received from a light source. Means may be provided for increasing the amount of power to the light source in response to a decrease in light output to maintain a substantially constant light output. The light source may be inside a housing and bonded to a heat sink attached to the back side of the housing to dissipate excess heat generated by the light source. Also the light source may comprise at least one LED that generates blue light output bands and at least one other LED that generates other color light output bands that are selectively mixed with the blue light output bands. | 04-16-2009 |
