A multicore processor system and a method of operating the system defines a processor partition (which may include one or more processor cores) as a network offload engine for a network connected to the processor system. Network operations requests from other cores or partitions of the processor system are forwarded to the network offload engine by a cross-platform inter-partition communications component including a relay task in the network offload engine for receiving network operations requests from network proxies in the other partitions. The network offload engine then controls access to network resources by the other cores or partitions and applications running thereon. A second or additional core or partition of the processor system may be similarly defined as a network offload engine for a second or additional network, receiving network operations requests from the other partitions through a similar system of relay task and network proxies.

Optimal multi-core network architecture

A system and method for ensuring a minimum required availability of a Hosted Function (HF) may retain an entirety of a cache content between separate instances of one or more HF which may share a cache resource. Based on controlling a relationship between an unavailability of cache memory desired by the HF to a probability of the available cache being unusable by the HF, each activation period may be variable within a tolerance to achieve a certification strategy. The approach may statistically characterize a best case, expected case, and worst case of cache availability. The system and method may determine a quality of the cache state at the activation of a particular HF and, based on the statistical analysis of that quality over time, determine a desired derated activation period for each HF to achieve a minimum level of computational availability for successful activation of the HF.

Cache retention analysis system and method

A multi-core processor system and a method of operating the system allocates fault queues in a shared system memory for each virtual machine of a partitioned guest operating system running on a core or partition of the processor system. Health monitors of the partitioned guest operating system log faults in the fault queue corresponding to the appropriate virtual machine. The health monitors may take additional action in response to warning-level or virtual machine-level faults. A health monitor of the multi-core processor resource then polls each fault queue, as well as the partition-level and module-level event logs maintained by the module operating system, for available faults and logs all faults in a single nonvolatile event log of the multi-core processor resource.
