Abstract: Systems and methods may provide a set of networked computational resources such as nodes that may be arranged in a hierarchy. A hierarchy of performance balancers receives performance samples from the computational resources beneath them and uses the performance samples to conduct a statistical analysis of variations in their performance. In one embodiment, the performance balancers steer power from faster resources to slower resources in order to enhance their performance, including in parallel processing.

Each of the cores may run code that is provided with a progress meter that calculates the amount of work remaining to be performed on threads as they run on their respective cores. The data may be collected continuously, and may be used to alter the frequency, speed or other operating characteristic of the cores as well as groups of cores. The progress meters may be annotated into existing code.

Abstract: Embodiments of the present invention provide a system that simulates a load on a computer system. The system starts by collecting a set of sampled values from one or more monitors in the computer system during the execution of program code. Next, the system uses the set of sampled values to determine if one or more repeating computational phases occurs during the execution of the program code. If one or more repeating computational phases occurs, the system subsequently simulates a load on the computer system by executing portions of the program code that caused each repeating computational phase one or more times.

Abstract: A system for binary code instrumentation to reduce effective memory latency comprises a processor and memory coupled to the processor. The memory comprises program instructions executable by the processor to implement a code analyzer configured to analyze an instruction stream of compiled code executable at an execution engine to identify, for a given memory reference instruction in the stream that references data at a memory address calculated during an execution of the instruction stream, an earliest point in time during the execution at which sufficient data is available at the execution engine to calculate the memory address. The code analyzer generates an indication of whether the given memory reference instruction is suitable for a prefetch operation based on a difference in time between the earliest point in time and a time at which the given memory reference instruction is executed during the execution.

Abstract: System and method for the unique naming of resources in networked environments including peer-to-peer network environments. Embodiments may be used to generate network resource identifiers that uniquely identify resources such as processes over time and across the networked environment. One embodiment may be implemented as a resource name generator that generates unique identifiers for resources in networked environments. One embodiment may generate unique network resource identifiers for processes from information including, but not limited to, a host address that uniquely identifies on the network the host machine of the resource for which the unique network resource identifier is being generated, a current time (e.g. obtained from the host machine or alternatively from an external source such as an atomic time server), and a process identifier of the process that uniquely identifies the process among current processes on the host machine.

Abstract: System and method for submitting and performing computational tasks in a distributed heterogeneous networked environment. Embodiments may allow tasks to be submitted and run in parallel on a network of heterogeneous computers implementing a variety of operating environments. In one embodiment, a user on an originating node may advertise code on the network. Peer nodes that respond to the advertisement may receive the code. A job to be executed by the code may be split into separate tasks to distributed to the peer nodes that received the code. These tasks may be advertised on the network. Tasks may be assigned to peer nodes that respond to the task advertisements. The peer nodes may then work on the assigned tasks. Once a peer node's work on a task is completed, the peer node may return the results of the task to the originating node.

Abstract: One embodiment of the present invention provides a system for generating an interconnection network. During operation, the system associates an n-bit binary identifier with each node in the interconnection network. The system also groups the n bits of each binary identifier into h overlapping sets a1, a2, . . . ah, wherein the sets a1, a2, . . . ah cover all of the n bits. For each set ai, the system forms fully connected clusters of nodes by creating a direct point-to-point link between any two nodes that have binary identifiers that differ in bits of the set a1 but are the same in other bit positions. Note that by varying the amount of overlap and the pattern of overlap between the overlapping sets, a1, a2, . . . ah, the interconnection network can be configured to accommodate different redundancy requirements.
