Abstract: Software for a distributed streaming platform receives a specification for a streaming application and converts the specification into a logical plan that includes a directed acyclic graph (DAG) with operators as nodes and streams as edges. The software translates the logical plan into a physical plan using any stream modes as specified and with one or more instances of the operators per any static partitioning. Then the software obtains a plurality of containers running on a networked cluster of servers. One slave executes in each container. The software assigns the instances to the slaves for execution according to an execution plan that depends at least in part on the physical plan and number of containers obtained. Each slave monitors throughput of the streaming windows through the instances in the container and other statistics related to service level and reports the results of the monitoring, which are used for dynamic adjustment.

Abstract: A sequence of storage devices of a data store may include one or more stripesets for storing data stripes of different lengths and of different types. Each data stripe may be stored in a prefix or other portion of a stripeset. Each data stripe may be identified by an array of addresses that identify each page of the data stripe on each included storage device. When a first storage device of a stripeset becomes full, the stripeset may be shifted by removing the full storage device from the stripeset, and adding a next storage device of the data store to the stripeset. A class variable may be associated with storage devices of a stripeset to identify the type of data that the stripeset can store. The class variable may be increased (or otherwise modified) when a computer stores data of a different class in the stripeset.

Abstract: Software for a distributed streaming platform receives an application that runs on a streaming platform. The application is structured as a directed acyclic graph (DAG) with instances of operators as nodes and streams as edges between nodes. The application is associated with a pre-defined hint that is a key-value pair. The software launches the application by assigning the instances of operators to containers provided by the streaming platform and initiating the streams. Then the software reads a value for the pre-defined hint and transmits the value to the application through an application programming interface (API) exposed by the streaming platform. The software receives a request from the application through the API to make a dynamic adjustment. And the software makes the dynamic adjustment and re-launches the application using a recovery policy.

Abstract: A communications technique using spare bit-lanes to communicate changes in interface physical link layer bandwidth and/or active width provides for dynamic adjustment of power consumption of interface links without requiring a separate control path for exchanging the change information. One or more spare bit-lanes are used to communicate an indication of the operating frequency/active width change to the physical link layer of the remote side of the interface and an acknowledgement is sent back to provide complete handshaking of the operating characteristic change. The method can determine whether or not a spare bit-lane is available and prevent making the change if a spare bit-lane is not available until the interface is repaired and a spare bit-lane can then be used for communicating operating changes in operating frequency/active width.

Abstract: Efficient techniques are described for reducing cache pollution by use of a prefetch logic that recognizes exits from software loops or function returns to cancel any pending prefetch request operations. The prefetch logic includes a loop data address monitor to determine a data access stride based on repeated execution of a memory access instruction in a program loop. Data prefetch logic then speculatively issues prefetch requests according to the data access stride. A stop prefetch circuit is used to cancel pending prefetch requests in response to an identified loop exit. The prefetch logic may also recognize a return from a called function and cancel any pending prefetch request operations associated with the called function. When prefetch requests are canceled, demand requests, such as based on load instructions, are not canceled. This approach to reduce cache pollution uses program flow information to throttle data cache prefetching.

Abstract: An invention is provided for filtering cached input/output (I/O) data. The invention includes receiving a current I/O transfer. Embodiments of the present invention evaluate whether to filter ongoing data streams once the data stream reaches are particular size threshold. The current I/O transfer is part of an ongoing sequential data stream and the total data transferred as part of the ongoing sequential data stream is greater than the predetermined threshold.

The current I/O transfer is cached when the transfer rate is greater than the throughput associated with a target storage device, or is not cached when the transfer rate is not greater than the throughput associated with a target storage device.

Abstract: A Data Throttling method duplicates the full-speed transmission of data so that it appears to be transmitting at a 10 Mhz rate. Additional storage elements and multiplexers are added along the data path but this completely eliminates undesirable complexity in the clock tree. In a two-bit application, data is received and transmitted two bits at a time, and yet the output 10 Mhz data rate is maintained. For an even ratio between the system clock rate and the 10 Mhz clock signal rate, bit0 is transmitted for half the time and bit1 is transmitted for the other half of the time. But if the full-speed clock rate is an odd multiple of 10 Mhz, then there will be a “split cycle” including one bit0 and one bit1.

Abstract: Techniques are described for eliminating backpressure in a distributed system by changing the rate data flows through a processing element. Backpressure occurs when data throughput in a processing element begins to decrease, for example, if new processing elements are added to the operating chart or if the distributed system is required to process more data. Indicators of backpressure (current or future) may be monitored. Once current backpressure or potential backpressure is identified, the operator graph or data rates may be altered to alleviate the backpressure. For example, a processing element may reduce the data rates it sends to processing elements that are downstream in the operator graph, or processing elements and/or data paths may be eliminated. In one embodiment, processing elements and associate data paths may be prioritized so that more important execution paths are maintained.

Abstract: Embodiments of the present invention provide an approach for a networked computing environment (e.g., a cloud computing environment) to be dynamic in nature in that it may automatically be resized based on current/predicted workload and current/predicted resource availability. For example, when a workload is received, a data structure (e.g., a mapping) will be created on a computer storage device and populated with data related to a set of current resources of the networked computing environment that are allocated to the workload. It will then be determined whether a mismatch (e.g., a shortfall) exists between the set of current resources and resources required for processing the workload. If so, a set of peripheral resources will be identified to rectify the mismatch. The networked computing environment will then be resized to accommodate the set of peripheral resources, and the workload will be processed using the resized networked computing environment.
