20090276205 | STABLIZING OPERATION OF AN EMULATED SYSTEM - Disclosure of approaches for stabilizing an emulated system. In one approach, a first operating system (OS) is executed on an instruction processor, the first OS including instructions native to the instruction processor. A second OS and a plurality of application programs are emulated on the first OS. The second OS polls the first OS for memory statistics of the first OS. The memory statistics indicate a current state of operating parameters of the memory of the data processing system used by the first OS in managing the data processing system. The second OS controls a number of the application programs allowed to execute in response to the memory statistics provided by the first OS to the second OS. | 11-05-2009 |
20100064073 | Input/output completion system and method for a data processing platform - A mechanism is disclosed for performing I/O operations using queue banks within a data processing system that supports multiple processing partitions. A queue bank is a re-useable area of memory allocated for performing I/O operations. All memory locking and address-translation functions are generally performed only once for a queue bank to reduce system overhead. After a queue bank has been used to perform an I/O operation, some processing is performed to make it available for re-use. This processing determines whether the queue bank contains memory that is being removed from a current processing partition. If so, a delay is imposed so that the queue bank is not made available for immediate re-use. This creates a window of time wherein all queue banks that contain the affected memory are inactive, thereby allowing the affected memory to be removed from the partition without halting on-going I/O activity. | 03-11-2010 |

20100125554 | Memory Recovery Across Reboots of an Emulated Operating System - Approaches for recovering state data between boot sessions of an emulated operating system (OS). An OS is emulated on a host OS. In response to each memory acquire request from the emulated OS, an interface to the host OS returns a memory area for use by the emulated OS and stores allocation data associated with the memory area. The allocation data includes an address referencing the memory area and a boot sequence number that indicates a boot session of the emulated OS. While booting the second emulated OS to a current boot session, the stored allocation data is retrieved from the interface, and in response to the stored allocation data including a selected boot sequence number, data from the memory area referenced by the address in the allocation data is stored in retentive storage by the second OS. | 05-20-2010 |
20120072908 | SYSTEM AND METHOD FOR AFFINITY DISPATCHING FOR TASK MANAGEMENT IN AN EMULATED MULTIPROCESSOR ENVIRONMENT - The disclosure relates generally to managing assignment of tasks among instruction processors (IPs) within a computer system having multiple IPs, and more particularly to binding emulated IPs with a host system's IPs (e.g., processor cores) for facilitating control over affinity-based assignment of tasks among the host system's IPs by a task manager (e.g., OS) that is executing on the emulated IPs, rather than running directly on the host system's IPs. Certain embodiments provide techniques for binding emulated IPs with actual IPs of a computing system that is hosting the emulated IPs, thereby enabling better control of management of the system by a task manager executing on the emulated IPs. For instance, in certain embodiments, a dispatcher (e.g., of an OS running on emulated IPs) performs affinity-based management of task assignment for tasks performed for an application program among IPs of a host system that is hosting the emulated IPs. | 03-22-2012 |
