Abstract: A profiler may analyze processes being run by a processor. The profiler may include logic to periodically sample a value of an instruction pointer that indicates an instruction in the first process that is currently being executed by the processor and logic to update profile data based on the sampled value. The profiler may additionally include logic to determine, in response to a context switch that includes the operating system switching the active process from the first process to another of the plurality of processes, whether the first process executes for greater than a first length of time; logic to stop operation of the profiler when the first process executes for greater than the first length of time; and logic to clear the profile data when the first process fails to execute for greater than the first length of time.

Abstract: The disclosed computer-implemented method for facilitating atomic delivery of bundled data sets to applications within distributed systems may include (1) receiving, at a queue of an application, a data set from at least one other application, (2) determining that the data set is incorporated in a bundle whose contents have yet to completely arrive at the queue, (3) gating the data set at the queue until the bundle's contents have completely arrived at the queue, (4) receiving, at the queue, another data set incorporated in the bundle, (5) determining that the bundle's contents have completely arrived at the queue based at least in part on receiving the other data set, and then (6) notifying the application that the bundle is ready for atomic delivery such that the application is able to consume the bundle's contents on an as-needed basis. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A device identifies, based on a program code instruction, an attempted write access operation to a fenced memory slab, where the fenced memory slab includes an alternating sequence of data buffers and guard buffers. The device assigns read-only protection to the fenced slab and invokes, based on the attempted write access operation, a page fault operation. When a faulting address of the attempted write operation is not an address for one of the multiple data buffers, the device performs a panic routine. When the faulting address of the attempted write operation is an address for one of the multiple data buffers, the device removes the read-only protection for the fenced slab and performs a single step processing routine for the program code instruction.

Abstract: A network device obtains a data package associated with an ISSU procedure and determines, based on the data package, that a control plane of the network device is to be rebooted to facilitate performance of the ISSU procedure. The network device causes, based on determining that the control plane is to be rebooted, a plurality of applications of the network device to stop executing on the network device and a control plane state of the network device to be frozen. The network device then causes the ISSU procedure to be performed. The network causes, based on causing the ISSU procedure to be performed, the control plane state of the network device to be restored and the plurality of applications to resume executing on the network device.

Abstract: A network device receives first objects defining first network data associated with an asynchronous distributed network and an asynchronous distributed network operating system and generates a natural name graph based on the first objects. The network device provides information describing the natural name graph to other network devices in the asynchronous distributed network and receives a second object defining second network data. The network device determines whether one of the first objects in the natural name graph is a duplicate of the second object and removes the one of the first objects from the natural name graph, to generate an updated natural name graph, when the one of the first objects in the natural name graph is a duplicate of the second object. The network device provides the updated natural name graph to the other network devices to prevent the other network devices from generating erroneous results.
