A data processing system includes a system fabric, a system memory, a memory controller, and a link controller communicatively coupled to the system fabric and configured to be communicatively coupled, via a communication link to a destination host with which the source host is non-coherent. A plurality of processing units is configured to execute a logical partition and to migrate the logical partition to the destination host via the communication link. Migration of the logical partition includes migrating, via a communication link, the dataset of the logical partition executing on the source host from the system memory of the source host to a system memory of the destination host. After migrating at least a portion of the dataset, a state of the logical partition is migrated, via the communication link, from the source host to the destination host, such that the logical partition thereafter executes on the destination host.

Migration of a logical partition between mutually non-coherent host data processing systems

An electronic product can be configured by a method that includes attaching a machine-readable identification (ID) tag containing an ID code to a hardware unit of the electronic product. The ID code is associated with a particular configuration of the electronic product, and can be read or scanned with a mobile device configured to send the ID code to a provider server device. In response to receiving the ID code, the provider server device can send product configuration instructions and a product configuration application to the mobile device. The product configuration instructions can guide a user through a customized series of electronic product configuration operations. The product configuration application can assist the user in performing configuration operations, can provide customized configuration help, and can establish a wireless link between the mobile device and the electronic product, allowing the user to interact with the electronic product.

A unified request queue includes multiple entries for servicing multiple types of requests. Each of the entries of the unified request queue is generally allocable to requests of any of the multiple request types. A number of entries in the unified request queue is reserved for a first request type among the multiple types of requests. The number of entries reserved for the first request type is dynamically varied based on a number of requests of the first request type rejected by the unified request queue due to allocation of entries in the unified request queue to other requests.

Dynamic reservations in a unified request queue

Provided is a technology to scan a document for file attachments, generate alternative file names corresponding to a particular attachment, determine whether or not the particular file attachment is the latest version of a file or has a name and/for file path that could he confused with the name and/or path of another file. In the event one or more of the above conditions is met, techniques are also provided to verify that the file attachment is the desired file and, if necessary, to select an alternative file for attachment.

Reducing errors in sending file attachments

An information handling system includes a processor with multiple hardware units that generate program application load, store, and I/O interface requests to system busses within the information handling system. The processor includes a resource allocation identifier (RAID) that links the processor hardware unit initiating a system bus request with a specific resource allocation group. The resource allocation group assigns a specific bandwidth allocation rate to the initiating processor. When a load, store, or I/O interface bus request reaches the I/O bus for execution, the resource allocation manager restricts the amount of bandwidth associated with each I/O request by assigning discrete amounts of bandwidth to each successive I/O requester. Successive stages of the instruction pipeline in the hardware unit contain the resource allocation identifiers (RAID) linked to the specific load, store, or I/O instruction.

Method and apparatus for enabling resource allocation identification at the instruction level in a processor system

The claimed subject matter comprises a technology to scan a document for file attachments, generate alternative file names corresponding to a particular attachment, determine whether or not the particular file attachment is the latest version of a file or has a name and/or file path that could be confused with the name and/or path of another file. In the event one of the above conditions are met, the technology provides the means for a user to verify that the file attachment is the desired file and, if necessary, to select an alternative file for attachment.

A mechanism for broadcasting instructions/data to a plurality of processors in a multiprocessor device via aliasing is provided. In order to broadcast data to a plurality of processors, a control processor writes to the registers that store the identifiers of the processors and sets two or more of these registers to a same value. The control processor may write the desired data/instructions to be broadcast to a portion of memory corresponding to the starting address associated with the processor identifier of the two or more processors. When the two or more processors look for a starting address of their local store from which to read, the two or more processors will identify the same starting address, essentially aliasing the memory region. The two or more processors will read the instructions/data from the same aliased memory region starting at the identified starting address and process the same instructions/data.

A system and method for incorporating design behavior and external stimulus in microdevice model feedback using a shared memory is presented. The invention describe herein uses the attached memory model to provide additional heuristics to an application executing on an emulation system's device model, which results in a more detail and real-life device emulation. The attached memory model provides a storage area for a runtime software environment to store emulation data, which is subsequently provided to the device model during emulation. The emulation data may include 1) randomization stimuli to the device model, 2) additional runtime data for checking heuristics, and 3) emulation data points that are otherwise not accessible to the device model.

One of the processors of a multiprocessor system is chosen to be a boot processor. The other processors of the multiprocessor system execute masking code that generates electromagnetic and/or thermal signatures that mask the electromagnetic and/or thermal signatures of the actual boot processor. Such masking may involve running the same boot code as the boot processor but without obtaining access to security information, such as the security key for accessing the system. The electromagnetic and/or thermal signatures generated by the execution of the masking code preferably approximate the electromagnetic and/or thermal signatures of the actual boot code executing on the boot processor. In this way, it is difficult to distinguish which processor is the actual boot processor.

Masking a hardware boot sequence

Masking a boot sequence by providing a dummy processor is provided. One of the processors of a multiprocessor system is chosen to be a boot processor. The other processors of the multiprocessor system execute masking code that generates electromagnetic and/or thermal signatures that mask the electromagnetic and/or thermal signatures of the actual boot processor. The execution of the masking code on the non-boot processors preferably generates electromagnetic and/or thermal signatures that approximate the signatures of the actual boot code execution on the boot processor. One of the non-boot processors is selected to execute masking code that is different from the other masking code sequence to thereby generate an electromagnetic and/or thermal signature that appears to be unique from an external monitoring perspective.
