| 20090150893 | HARDWARE UTILIZATION-AWARE THREAD MANAGEMENT IN MULTITHREADED COMPUTER SYSTEMS - A device, system, and method are directed towards managing threads in a computer system with one or more processing units, each processing unit having a corresponding hardware resource. Threads are characterized based on their use or requirements for access to the hardware resource. The threads are distributed among the processing units in a configuration that leaves at least one processing unit with threads that have an aggregate zero or low usage of the hardware resource. Power may be reduced or turned off to the instances of the hardware resource that have zero or low usage. Distribution may be based on one or more of a number of specifications or factors, such as user power management specifications, power usage, performance, and other factors. | 06-11-2009 |
| 20090217277 | USE OF CPI POWER MANAGEMENT IN COMPUTER SYSTEMS - A device, system, and method are directed towards managing power consumption in a computer system with one or more processing units, each processing unit executing one or more threads. Threads are characterized based on a cycles per instruction (CPI) characteristic of the thread. A clock frequency of each processing unit may be configured based on the CPI of each thread assigned to the processing unit. In a system wherein higher clock frequencies consume greater amounts of power, the CPI may be used to determine a desirable clock frequency. The CPI of each thread may also be used to assign threads to each processing unit, so that threads having similar characteristics are grouped together. Techniques for assigning threads and configuring processor frequency may be combined to affect performance and power consumption. Various specifications or factors may also be considered when scheduling threads or determining processor frequencies. | 08-27-2009 |

| 20080239942 | SYSTEMS AND METHODS FOR VERIFYING RECOVERY FROM AN INTERMITTENT HARDWARE FAULT - Systems and methods for verifying recovery from intermittent hardware faults. Exemplary embodiments include a method for verifying recovery from intermittent hardware faults, the method including generating an error in a computer interface by forcing a hardware fault after setting an error injection enable control bit in a register coupled to the computer interface, detecting an error in a hardware checker coupled to the computer interface which asserts an error interrupt signal resetting the error injection enable control bit when the error interrupt signal and a hardware reset control bit coupled to the computer interface are both active, disabling error forcing when the error injection enable control bit is reset, and executing an error recovery and logging procedure in the computer interface. | 10-02-2008 |

| 20090006496 | Methods of determining and searching for modified blocks in a file system - The invention relates to a method of determining if a block was modified in a file system by comparing the versions of the base snapshot, the delta snapshot, and the space map block entry (b, e). In another aspect, the invention relates to a method of searching for blocks modified in a tree structured file system. The invention relates to methods and systems of snapshot management of a file system in a data storage system. To represent the snapshots, the invention maintains pointers to the root block pointer of each snapshot. When the active file system is modified, this invention avoids overwriting any blocks used by previous snapshots by allocating new blocks for the modified blocks. When the invention needs to put an established block in a new location, it must update a parent block to point to the new location. The update to the parent block may then require allocating a new block for the new parent block and so forth. Parts of the file system not modified since a snapshot remain in place. The amount of space required to represent snapshots scales with the fraction of the file system that users modify. To maintain snapshot integrity, this invention keeps track of the first and last snapshots that use each block in space map blocks spread throughout the file system data space. When users delete snapshots, this invention may use a background process to find blocks no longer used by any snapshot and makes them available for future use. | 01-01-2009 |

| 20110148589 | Real-Time Location System Using Tag Interrogator and Embedded or Fixed Tag Transmitters - A system tracks vehicles within a terminal and includes at least one tag interrogator mounted on a vehicle to be identified and tracked within the terminal. The tag interrogator is operative for emitting a signal containing data identifying the vehicle to which the tag interrogator is mounted. At least one tag transmitter is fixed at a known location within the terminal where vehicles are to be identified and receptive to a tag interrogator on the vehicle when the vehicle passes within proximity to the fixed tag transmitter for transmitting a wireless RF signal having data identifying the tag transmitter and identifying the tag interrogator as an identifier for the vehicle to which the tag interrogator is mounted. At least one access point is positioned at the terminal for receiving the RF signal from the tag transmitter for subsequent processing to verify vehicle identity at the known location. | 06-23-2011 |
