摘要:
Methods, apparatus, and products for processor fault isolation are disclosed that include sending, by an embedded system microcontroller to a programmable logic device (‘PLD’) a selection signal identifying one processor for boundary scan operations; sending boundary scan input signals to be sent to the identified processor; multiplexing by the PLD the boundary scan input signals to the identified processor; and sending boundary scan output signals returned from the identified processor. Methods, apparatus, and products for processor fault isolation are also disclosed that include connecting two or more processors in a boundary scan test chain, the connecting carried out by a PLD of a computer, the PLD further connected to sense lines carrying presence signals indicating whether processors are present in the computer; and including in the chain all processors indicated present according to presence signals.

An information handling system includes a processor with one or more channels for communicating to peripheral devices controlled by peripheral device controllers, and one or more serial data links between the channels and the peripheral controllers. Data is transmitted over the serial data link between the channels and the controllers in a frame format, wherein each frame includes a number of eight-bit characters selected so that all standard parallel interface tag and data lines are transmitted in a single frame with a high degree of error immunity resulting from selection of idle characters and frame start characters having the mutual characteristic that single and double bit errors in the idle characters do not create an erroneous indication of a start character in the system.

A method, system, and computer-readable storage media for granting a device access to a managed group are disclosed. Identification information may be exchanged between a management device in the managed group and a managed device through a secure first channel. If the identification information is verified by the management device, the managed device may be granted access to the managed group through the secure first channel. If access is granted, the managed device may access the managed group through a secure communication session on a network. If the identification information is not verified, the management device may send a cryptographic key to the managed device through the secure first channel. The cryptographic key may be used to create an encrypted communication session between the managed device and management device over the network.

A host machine provisions a virtual machine from a catalog of stock virtual machines. The host machine instantiates the virtual machine. The host machine configures the virtual machine, based on customer inputs, to form a customer's configured virtual machine. The host machine creates an image from the customer's configured virtual machine. The host machine unwraps a sealed customer's symmetric key to form a customer's symmetric key. The host machine encrypts the customer's configured virtual machine with the customer's symmetric key to form an encrypted configured virtual machine. The host machine stores the encrypted configured virtual machine to non-volatile storage.

A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design for addressing deficiencies of the art in respect to hypertransport-based switching for multi-CPU systems and for flexibly configurable multi-CPU supported hypertransport switching is provided. The design structure can include a hypertransport switching data processing system. The system can include a CPU and at least two I/O bridges. Each I/O bridge can provide a communications path for data driven to a corresponding peripheral device from the CPU. Notably, the system can include a flexibly configurable hypertransport switch. The switch can include a first configuration adapting the CPU to both of the I/O bridges, and a second configuration adapting the CPU to a first one of the I/O bridges and a second CPU to a second one of the I/O bridges.

Roundball is a sports event that is based on the same primitive activity that forms the basis of three other games, namely, basketball, 21st Century Challenge America Basketball Game, and Method for Playing a Basketball-Type Game. The latter two are patented. All four are singular games by virtue of their completely different formats. Roundball games are composed of rounds, like boxing matches; and the winner of the game is the team that accumulates the majority of the points in each of the majority of the rounds. Roundball games will be suspenseful from start to finish, with clear and reasonable results. There is good reason to expect that professional Roundball will become a strong competitor for a share of the multi-billion-dollar entertainment industry market. There is no record of anyone else having conceived the same idea; which is strong empirical evidence that your petitioner is the inventor of Roundball.

Embodiments of the invention address deficiencies of the art in respect to hypertransport-based switching for multi-CPU systems and provide a method, system and computer program product for flexibly configurable multi-CPU supported hypertransport switching. In one embodiment of the invention, a hypertransport switching data processing system can be provided. The system can include a CPU and at least two I/O bridges. Each I/O bridge can provide a communications path for data driven to a corresponding peripheral device from the CPU. Notably, the system can include a flexibly configurable hypertransport switch. The switch can include a first configuration adapting the CPU to both of the I/O bridges, and a second configuration adapting the CPU to a first one of the I/O bridges and a second CPU to a second one of the I/O bridges.
摘要:
Method, apparatus and computer program product are provided for operating a plurality of computer nodes while maintaining trust. A primary computer node and at least one secondary computer node are connected into a cluster, wherein each of the clustered computer nodes includes a trusted platform module (TPM) that is accessible to software and includes security status information about the respective computer node. Each clustered computer node is then merged into a single node with only the TPM of the primary computer node being accessible to software. The TPM of the primary computer node is updated to include the security status information of each TPM in the cluster. Preferably, the step of merging is controlled by power on self test (POST) basic input output system (BIOS) code associated with a boot processor in the primary node.
