Maintaining cryptoprocessor types in a multinode system includes receiving a selection of a cryptoprocessor type; identifying, within a multinode system, a node having a cryptoprocessor of the selected cryptoprocessor type; and designating the node having the cryptoprocessor of the selected cryptoprocessor type as a primary node for the multimode system.

Methods, apparatuses, and computer program products for indicating a page number of an active document page within a document are provided. Embodiments include detecting, by a presentation controller, activation of a document page on a presentation device; in response to detecting the activation of the document page on the presentation device, tracking, by the presentation controller, an amount of time that the document page is consecutively active on the presentation device; determining, by the presentation controller, that the amount of time that the document page is consecutively active on the presentation device exceeds a predetermined threshold; and in response to determining that the predetermined threshold has been exceeded, providing to a target source, by the presentation controller, an output indicating a page number of the document page while the document page is active on the presentation device.

A method and/or computer program product automatically adjusts room temperature in a data center room. A processor in a heating, ventilation and air conditioning (HVAC) system receives a throttle threshold temperature for each of multiple computing devices that are within a data center room, which is climate-controlled by the HVAC system. The processor in the HVAC system monitors a real-time temperature of at least one of the multiple computing devices. In response to the real-time temperature of said at least one of the multiple computing devices exceeding the throttle threshold temperature, an ambient air temperature in the data center room is decreased by adjusting a hardware thermostat in the HVAC system.

Optimizing computer hardware usage in a computing system that includes a plurality of populated central processing unit ('CPU') sockets, including: determining, by a socket configuration module, a number of CPUs to be utilized during operation of the computing system; determining, by the socket configuration module, error characteristics associated with each available CPU, wherein the error characteristics associated with each available CPU include error information for computing devices that are coupled to one or more of the available CPUs; and selecting, by the socket configuration module in dependence upon the error characteristics associated with each available CPU and a predetermined error tolerance policy, a target CPU to utilize as a boot CPU.

Provisioning memory in a memory system for mirroring includes: gathering, by a memory controller, margin data for memory in the memory system, the margin data representing susceptibility for error; identifying, by the memory controller in dependence upon provisioning criteria and the margin data, mirroring candidates within the memory system; and mirroring, by the memory controller, memory of the memory system utilizing the mirroring candidates as a mirrored backup of other memory in the memory system.

A system includes a multi-node chassis including a chassis management module, a plurality of compute nodes, and a physical presence manual actuator for transmitting a physical presence signal to each compute node in response to manual actuation. Each server has a firmware interface, a trusted platform module, and an AND gate. The firmware interface has a general purpose input output pin for providing an enabling signal in response to a user instruction to a firmware interface setup program that communicates with the firmware interface. The AND gate has a first input receiving the enabling signal, a second input receiving the physical presence signal, and an output coupled to the trusted platform module, wherein the AND gate for a selected compute node asserts physical presence to the trusted platform module of the selected compute node in response to receiving both the enabling signal and the physical presence signal.

A computer program product includes a computer readable storage medium having program instructions embodied therewith, where the program instructions are executable by a processor to cause the processor to perform a method of communication. The method includes a communication hub receiving a message via short range wireless communication directly from a first mobile communication device that is proximate to the communication hub at the time the message is transmitted, and the communication hub receiving the message and automatically forwarding the message via a mobile communications network to a second mobile communication device that is associated with the communication hub without the first mobile communication device identifying the second mobile communication device.

A compute node includes a motherboard having a trusted platform module, and also includes a port for selectively coupling a hot pluggable device into communication with the motherboard. The compute node further includes a circuit coupled to the port for detecting a change in the physical connection of the hot pluggable device to the port and for asserting a physical presence signal to the trusted platform module in response to detecting a change in the physical connection of the hot pluggable device to the port. The change in the physical connection of the hot pluggable device to the port may include either physically connecting the hot pluggable device to the port, physically disconnecting the hot pluggable device from the port, or a combination thereof.

Asserting physical presence to a trusted platform module by physically connecting or disconnecting a hot pluggable device

A method includes asserting a physical presence signal to a trusted platform module of a compute node in response to detecting a change in the physical connection of a hot pluggable device to a port of the compute node. The change in the physical connection of the hot pluggable device to the port is selected from physically connecting the hot pluggable device to the port, physically disconnecting the hot pluggable device from the port, and combinations thereof. Optionally, the compute node has a USB port and the hot pluggable device has a USB connector that is selectively physically connectable to the USB port. In one example, detecting a change in the physical connection of the hot pluggable device to the compute node includes detecting a voltage change on the USB port.

A method uses a firmware interface setup program for a selected compute node ('node') to cause a firmware interface to enable a trusted platform module (TPM) on the selected node to receive a physical presence (PP) signal. The selected node is selected from a plurality of nodes within a multi-node chassis, wherein each node includes a firmware interface and a TPM. A device within the multi-node chassis is manually actuated to transmit a PP signal to each of the plurality of nodes, such that each node receives the PP signal. The PP signal is asserted to the TPM of the selected node in response to both enabling the TPM of the selected node to be able to receive the PP signal and receiving the PP signal. Still further, the method allows modification of a security setting of the selected node in response to the TPM receiving the PP signal.
