A distributed processing system delegates the allocation and control of computing work units to agent applications running on computing resources including multi-processor and multi-core systems. The distributed processing system includes at least one agent associated with at least one computing resource. The distributed processing system creates work units corresponding with execution phases of applications. Work units can be associated with concurrency data that specifies how applications are executed on multiple processors and/or processor cores. The agent collects information about its associated computing resources and requests work units from the server using this information and the concurrency data. An agent can monitor the performance of executing work units to better select subsequent work units. The distributed processing system may also be implemented within a single computing resource to improve processor core utilization of applications. Additional computing resources can augment the single computing resource and execute pending work units at any time.

The invention relates to the control of servers which process client work requests in a computer system on the basis of resource consumption. Each server contains multiple server instances (also called "execution units") which execute different client work requests in parallel. A workload manager determines the total number of server containers and server instances in order to achieve the goals of the work requests. The number of server instances started in each server container depends on the resource consumption of the server instances in each container and on the resource constraints, service goals and service goal achievements of the work units to be executed. At predetermined intervals during the execution of the work units the server instances are sampled to check whether they are active or inactive. Dependent on the number of active server instances the number of server address spaces and server instances is repeatedly adjusted to achieve an improved utilization of the available virtual storage and an optimization of the system performance in the execution of the application programs.

The present invention relates to a medical manipulator and a medical robot system. The manipulator has a connecting block, a joint shaft, and a distal-end working unit. The distal-end working unit has a gripper, a pitch axis, and a yaw axis which serve as distal-end joints for changing the orientation of the gripper. The gripper, the pitch axis, and the yaw axis are operated by rotors around which wires are wound. The joint shaft has a first intermediate joint and a second intermediate joint which are bendable by the wires which are moved back and forth. Since the manipulator can be bent at the first intermediate joint and the second intermediate joint, the joint shaft can appropriately be placed, and the gripper can be adjusted to an appropriate orientation with respect to an organ by being turned around the pitch axis and the yaw axis.

Techniques for multi-stage multi-core processing of network packets are described herein. In one embodiment, work units are received within a network element, each work unit representing a packet of different flows to be processed in multiple processing stages. Each work unit is identified by a work unit identifier that uniquely identifies a flow in which the associated packet belongs and a processing stage that the associated packet is to be processed. The work units are then dispatched to multiple core logic, such that packets of different flows can be processed concurrently by multiple core logic and packets of an identical flow in different processing stages can be processed concurrently by multiple core logic, in order to determine whether the packets should be transmitted to one or more application servers of a datacenter. Other methods and apparatuses are also described.

A system and method for automatically migrating the execution of work units between multiple heterogeneous cores. A computing system includes a first processor core with a single instruction multiple data micro-architecture and a second processor core with a general-purpose micro-architecture. A compiler predicts execution of a function call in a program migrates at a given location to a different processor core. The compiler creates a data structure to support moving live values associated with the execution of the function call at the given location. An operating system (OS) scheduler schedules at least code before the given location in program order to the first processor core. In response to receiving an indication that a condition for migration is satisfied, the OS scheduler moves the live values to a location indicated by the data structure for access by the second processor core and schedules code after the given location to the second processor core.

In a workload managed system comprising a plurality of server processes each capable of supporting a given program entity, such as an Enterprise JavaBeans™ specified stateful session bean, a stateful session bean instance is passivated, by writing it to a bean store, on completion of a unit of work. On next use the session bean is reactivated, by reading it from the bean store, in any one of the plurality of servers thereby allowing workload management for stateful session beans. A routing table is maintained, in non-volatile mass storage, that contains location information for units of work and stateful session bean instances, used to maintain unit of work-server affinity for the lifetime of the unit of work Stateful session beans instances are associated with ID keys that include a flag that is used to indicate whether or not the routing table contains location information for the bean instance.
