Abstract: This invention enables authenticated communications (transactions) to take place on a standard I2C bus without requiring modification of existing I2C devices. Read and write transactions occurring on the bus are authenticated using an Authentication Agent and a shared secret key. In addition to allowing verification of the legitimacy of the transactions, the authentication of the I2C transactions enhances the reliability and serviceability of the bus and devices on the bus by allowing the Baseboard Management Controller (BMC) to quickly determine and pinpoint errors.

Abstract: A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design is for securing of leased resources on a computer. The design structure includes a computer for securing resources may comprise at least one processor, a plurality of resources, wherein each resource is associated with configuration data and a programmable logic device connected to each of the plurality of resources. The programmable logic device may be configured for determining whether a resource is leased, reading un-encoded configuration data from a resource, and sending the configuration data to a first unit, if the resource is not leased. The programmable logic device may further be configured for reading encoded configuration data from a resource, decoding the configuration data, sending the configuration data that was decoded to a first unit, and logging use of the resource by the first unit, if the resource is leased.

Abstract: The invention is directed to a method for correlating processor usage to customer billing in an on-demand server with real-time allocation/deallocation of processing resources. A method in accordance with an embodiment of the present invention includes: providing a plurality of processors, each processor having thermal control circuit (TCC) logic; determining a processing requirement for the plurality of processors; and dynamically controlling a processing capability of the plurality of processors to provide the determined processing requirement by selectively enabling or disabling the TCC logic of each processor.

Abstract: In some embodiments, a memory control device includes a sensor positioned remotely from a memory device, a register to store an offset value, the offset value corresponding to a difference between a temperature reading of the sensor and an estimated actual temperature of the memory device, and a controller to control an operation of the memory device, wherein the controller is configured to read the offset value from the register and control the operation of the memory device in accordance with the offset value. The controller may be configured to dynamically update the offset value during an operation of the memory device. Other embodiments are disclosed and claimed.

Abstract: Methods and apparatus dynamically reconfigure storage or channel capacities in a memory system. A fully-buffered dual in-line memory module (DIMM) is configured for a particular storage capacity and a particular channel capacity. An error may be detected at a memory address in some portion of the DIMM. To resolve the problem, the storage capacity or the channel capacity may be reduced and the DIMM may be dynamically reconfigured according to the reduced capacity. For one embodiment the DIMM may be reconfigured by mapping the portion of the DIMM containing the error as unavailable and taking that portion off-line without taking the entire DIMM off-line. For another embodiment the DIMM may be reconfigured by throttling the DIMM at a reduced frequency. The portion of the DIMM containing the error may be retested at the reduced frequency. If no errors are detected, the DIMM may be made available at the reduced frequency.

Abstract: A processing system includes multiple processing units. After multiple event handlers have been dispatched to execute concurrently in different processing units of the processing system in a hidden execution mode, the processing system automatically determines whether the multiple event handlers successfully complete. If an event handler among the multiple dispatched event handlers fails, the processing system automatically dispatches another event handler to perform operations associated with the event handler that failed. In an embodiment, the hidden execution mode is a system management mode (SMM), and the multiple event handlers are dispatched in response to a system management interrupt (SMI) or a platform management interrupt (PMI). In an embodiment, the processing system may determine why the dispatched event handler failed, and may performing a corrective operation before dispatching another event handler to perform the operations associated with the event handler that failed.
