摘要:
Methods and apparatus for cell processors are disclosed. A policy module is loaded from a main memory of a cell processor into the local memory of a selected synergistic processing unit (SPU) under control of an SPU policy module manager (SPMM) running on the SPU. The policy module loads a work queue from the main memory into the local memory of the SPU. The policy module interprets and process one or more tasks from the work queue on the SPU. The selected SPU performs the task(s) and after completion or upon a pre-emption, returns control of the SPU to the SPMM.

A processor system and a processor readable medium, which implement a method for implementing multiple contexts on one or more SPE are disclosed. Code and/or data for a first and second contexts may be respectively stored simultaneously in first and second regions of an SPE's local memory, storing code and/or data for a second context in a second region of the local memory, the SPE may execute the first context while the second context waits. Code and/or data for the first context may be transferred from the first region to the second and code and/or data for the second context may be transferred from the second region to the first, and the SPE may execute the second context during a pause or stoppage of execution of the first context. Alternatively, the code and/or data for the second context may be transferred to another SPE's local memory.

An interconnectivity framework, method, and system for communicating in a peer-to-peer network is disclosed. A peer of the interconnectivity framework includes a peer library for publishing, messaging and locating component blocks over the peer-to-peer network and a telespace framework for managing component blocks in response to a requirement of an application to be executed at the peer. The component blocks being obtained by the peer library enable execution of the application at the peer in accordance with the requirement. The requirement defines the type of application so that the appropriate component blocks can be obtained from the peer-to-peer network. A networker is further included to enable communication with specific grids of the peer-to-peer network and to enable the publishing, messaging, and locating of objects published by specific peers of a grid of the peer-to-peer network.

A processor system may implement multiple contexts on one or more processors having a local memory. Code and/or data for first and second contexts may be respectively stored simultaneously in first and second regions of a processor's local memory, storing code and/or data for a second context in a second region of the local memory, the secondary processor may execute the first context while the second context waits. Code and/or data for the first context may be transferred from the first region to the second and code and/or data for the second context may be transferred from the second region to the first, and the processor may execute the second context during a pause or stoppage of execution of the first context. Alternatively, the code and/or data for the second context may be transferred to another processor's local memory.

Apparatus and systems for implementing simulated environments are disclosed. Remote implementation of function calls is also disclosed. A simulated environment apparatus may include a plurality of simulation servers coupled to each other over data transfer links. The simulation servers may be configured to perform computations related to simulating an environment. A plurality of view servers may be coupled to the simulation servers over data transfer links. Each view server is configured to facilitate interaction between a plurality of client devices and the simulation servers. Each user device may control an avatar within the simulated environment. A simulated environment system may include a data center configured to communicate over a network with one or more remotely distributed client devices.
摘要:
Atomic operation may be implemented in a processor system comprising a main memory and a power processor element (PPE) including a power processor unit (PPU) coupled to an external cache. The PPE may atomically load data from a lock-line in the main memory into a first location X in the external cache. A size of the data and the lock line may be larger than a data size for the standard atomic operations that may be performed with the PPE. The data may be reserved in a second location Y in the external cache.

摘要:
Atomic operations may be implemented on a processor system having a main memory and two or more processors including a power processor element (PPE) and a synergistic processor element (SPE) that operate on different sized register lines. A main memory address containing a primitive is divided into a parity byte and two or more portions, wherein the parity byte includes at least one bit. A value of the parity byte determines which of the two or more portions is a valid portion and which of them is an invalid portion. The primitive is of a memory size that is larger than a maximum size for atomic operation with the PPE and less than or equal to a maximum size for atomic operation with the SPE. Read with reservation and conditional write instructions are used by both the PPE and SPE to access or update a value of the atomic.
摘要:
An overlay network uses flexible neighbor selection based on network address translation (NAT) to define routing between nodes. The NAT type is used as a flexible neighbor selection criteria, either alone or in conjunction with other criteria. A method of selecting a neighboring node for a first node in a distributed hash table network includes determining a desired key value for a node finger table entry and requesting a set of candidate neighboring nodes near this desired key value. The method determines a network address translation type of each of the set of candidate neighboring nodes and ranks the set of candidate neighboring nodes accordingly. The method selects one of the set of candidate neighboring nodes based on the ranking. The NAT types of candidate neighboring nodes are determined by sending probe messages or from data received from a central overlay network server.
