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.

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.

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.

Systems, methods and media for clearing a hung I2C bus are disclosed. In one embodiment, a monitor monitors the I2C bus data and clock lines and detects if a hung bus occurs. The monitor times packet transactions on the bus to determine if a maximum transaction time has elapsed while the lines are in a hung state. The monitor allows selective reset of individual slave devices and bus masters to clear a hung bus.

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 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.
