摘要： Platform controller, computer-readable storage media, and methods associated with initialization of a computing device. In embodiments, a platform controller may comprise a boot controller and one or more non-volatile memory modules, coupled with the boot controller. In embodiments, the one or more non-volatile memory modules may have first instructions and second instructions stored thereon. The first instructions may, when executed by a processor of a computing device hosting the platform controller, cause initialization of the computing device. The second instructions, when executed by the boot controller, may cause the boot controller to monitor at least a portion of the execution of the first instructions by the computing device and may generate a trace of the monitored portion of the execution of the first instructions. In embodiments, the trace may be stored in the one or more non-volatile memory modules. Other embodiments may be described and/or claimed.

摘要： In one embodiment, a peripheral controller coupled to a processor can include a storage controller. This storage controller can control access to a non-volatile storage coupled to the peripheral controller. The storage may include both secure and open partitions, and the storage controller can enable access to the secure partition only when the processor is in a secure mode. In turn, during unsecure operation such as third party code execution, visibility of the secure partition can be prevented. Other embodiments are described and claimed.

摘要： In some embodiments, the invention involves a system and method relating to system recovery in a fault resilient manner by isolating errors associated with the management engine (ME) UMA memory. BIOS logs errors occurring on memory within the system. The ME UMA is invisible to the host OS, so the OS will not be notified about the errors occurring in the ME UMA range. When an error threshold has been reached for a memory unit in which ME UMA resides, ME UMA data is migrated to a previously reserved backup region of memory and the ME is notified of the new ME UMA location. The faulty memory is flagged for replacement at a next maintenance cycle. Embodiments may be applied to workstations that utilize ECC memory protection which utilize AMT (Active Management Technology) and ME UMA. Other embodiments are described and claimed.

摘要： A peer-to-peer IT (Information Technology) backbone. The system includes at least one IT server and a plurality of client computers arranged in a peer-to-peer IT backbone. Each of the client computers includes an in-band processor, an out-of-band (OOB) microcontroller, and a storage device coupled to the in-band processor and OOB microcontroller. The storage device includes a reserved area for the OOB microcontroller to enable an IT-administration to push IT payloads from the at least one IT server onto the reserved area of at least one of the plurality of client computers. The IT payloads are disseminated throughout the peer-to-peer IT backbone by the OOB microcontroller of the client computers.

摘要： In some embodiments, the invention involves a system and method to provide maximal boot-time parallelism for future multi-core, multi-node, and many-core systems. In an embodiment, the security (SEC), pre-EFI initialization (PEI), and then driver execution environment (DXE) phases are executed in parallel on multiple compute nodes (sockets) of a platform. Once the SEC/PEI/DXE phases are executed on all compute nodes having a processor, the boot device select (BDS) phase completes the boot by merging or partitioning the compute nodes based on a platform policy. Partitioned compute nodes each run their own instance of EFI. A common memory map may be generated prior to operating system (OS) launch when compute nodes are to be merged. Other embodiments are described and claimed.

摘要： A system and method to implement a resilient compute center. A plurality of processing systems is initialized. Each of the processing systems capable of operation communicates status information about its operational health to a management module responsible for managing the processing systems. The management module reinitializing any of the processing systems, if the management module determines that any of the processing systems is operating in a degraded state based on the status information communicated to the management module.

摘要： A method and apparatus is described herein for fault resilient booting of a platform. Upon booting the platform, any boot routines marked are skipped. A current boot routine to be executed in a boot sequence is registered in nonvolatile memory. An attempt to execute the current boot routine is made. If the attempt is successful, the next boot entry is determined and skipped or executed, based on whether it is marked. However, if the execution fails the current boot routine is marked and, upon subsequent execution of the boot sequence, skipped.
