Abstract: The state of cache lines transferred into an out of caches of processing hardware is tracked by monitoring hardware. The method of tracking includes monitoring the processing hardware for cache coherence events on a coherence interconnect between the processing hardware and monitoring hardware, determining that the state of a cache line has changed, and updating a hierarchical data structure to indicate the change in the state of said cache line. The hierarchical data structure includes a first level data structure including first bits, and a second level data structure including second bits, each of the first bits associated with a group of second bits. The step of updating includes setting one of the first bits and one of the second bits in the group corresponding to the first bit that is being set, according to an address of said cache line.

Abstract: A method enables events associated with local applications to be handled at a user device while a remote desktop is being used at the user device. A notification of an event is presented on a display screen of the user device, over the remote desktop. The notification prompts a user to handle the event now or handle the event later. In response to the user selecting to handle the event now, a window of a local application associated with the event is displayed over the remote desktop and may be used by the user to handle the event.

Abstract: Automated computer-implemented methods and systems for discovering clusters of alerts triggered by abnormal events occurring with objects in a data center are described. In one aspect, alerts with start times in a sliding run-time window are retrieved from an alerts database. Each alert corresponds to a run-time event occurring with an object of the data center. Clusters of alerts in the sliding run-time window are detected based on the start times of the alerts and topological proximity of the objects. High priority alerts in the clusters of alerts are determined based on alert types. The events associated with discovered clusters of alerts and high priority alerts are displayed in a graphical user interface (“GUI”). Time evolution clustering of alerts and coverage evolution of alerts are over time based on the start times of the alerts and topological proximity of objects exhibiting abnormal behavior in the data center.

Abstract: Automated methods and systems for resolving potential root causes of performance problems with applications executing in a data center are described. The automated methods use machine learning to train an inference model that relates event types recorded in metrics, log messages, and traces of an application to values of a key performance indicator (“KPI”) of the application. The methods use the trained inference model to determine which of the event types are important event types that relate to performance of the application. In response to detecting a run-time performance problem in the KPI, the methods determine which of the important event has a higher probability of being the potential root cause of the performance problem. A graphical user interface displays an alert that identifies the application as having the run-time performance problem, identity of the important event types, and at least one recommendation for remedying the performance problem.

Abstract: A method for processing virtualization of computers that are part of a group into virtual computers is provided. The method includes obtaining relationship data from the computers, where the relationship data identifies parameters used to communicate within the group. Then, the method analyzes utilization parameters for each of the computers of the group. A visual model for proposed virtualization of the group of computers is then generated. The visual model identifies hosting machines designated to define a virtual computer for each of the computers, where the visual model provides a graphical illustration of the group of computers once converted to virtual computers. The method enables adjustment of the proposed virtualization of the group of computers. Then, an execution sequence of virtualization operations to be carried out is generated, if execution of the proposed virtualization is triggered, and the execution sequence is saved to storage and accessed upon execution.

Scale tests are used to verify functionality and performance of the TCP are performed on the mock hosts without any changes to the TCP.

Abstract: Examples herein include systems and methods for providing capacity forecasting for high-usage periods of a computing infrastructure. An example method can include segmenting a first portion of a data stream and generating a first core set for a forecasting model that predicts future usage of computing resources. The example method can further include segmenting a second portion of the data stream, generating a second core set, and using both core sets to forecast usage. The first core set can then be phased out after a predetermined time period has elapsed such that forecasting is based only on the second core set. The example method can further include defining at least two clusters of data and performing predictive analysis on that specific cluster. Cluster-specific results can be displayed on a GUI, which can also provide a user with options for increase or decrease computing resources based on the predictions.

Abstract: This disclosure is directed to processes and systems for generating data packets in a smart network interface controller (“SNIC”) of a host server computer. A smart packet generator (“spktgen”) controller receives a user command that contains directions for how packets are generated in the SNIC. The command is sent to a spktgen daemon that runs in a control core of the multicore processor. The spktgen daemon extracts the type of packet generator and packet parameters recorded in the command and sends the type of packet generator and packet parameters to a spktgen engine that also runs in the control core. The spktgen engine creates threads in each of one or more data cores of the multicore processor. Each thread comprises instructions for generating data packets from the data generated by data generating sources of the host in accordance with the type of packet generator and the packet parameters.

Abstract: Some embodiments provide a method of load balancing data message flows across multiple secure connections. The method receives a data message having source and destination addresses formatted according to a first protocol. Based on the source and destination addresses, the method selects one of the multiple secure connections for the data message. Each of the secure connections handles a first set of connections formatted according to the first protocol and a second set of connections formatted according to a second protocol that is an alternative to the first protocol. The method securely encapsulates the data message and forwards the encapsulated data message onto a network. The encapsulation includes an identifier for the selected secure connection.

Abstract: An interface software layer is interposed between at least one application and a plurality of coprocessors. A data and command stream issued by the application(s) to an API of an intended one of the coprocessors is intercepted by the layer, which also acquires and stores the execution state information for the intended coprocessor at a coprocessor synchronization boundary. At least a portion of the intercepted data and command stream data is stored in a replay log associated with the intended coprocessor. The replay log associated with the intended coprocessor is then read out, along with the stored execution state information, and is submitted to and serviced by at least one different one of the coprocessors other than the intended coprocessor.

Abstract: Described herein are systems, methods, and software to manage communication path configurations between edge gateways in a computing environment. In at least one implementation, a controller monitors network characteristics associated with routes from a first edge gateway to a second edge gateway and determines whether a first route configuration for the first edge gateway to communicate with the second edge gateway fails to satisfy criteria based on the network characteristics. If the first route configuration fails to satisfy the criteria, the controller determines a second route configuration and applies the second route configuration for the first edge gateway to communicate with the second edge gateway.
