The system issues a first instruction, which involves setting, in a first entry for the first instruction in a data structure, a first prefetch region identifier with a current value of the global counter. Responsive to a head pointer of the data structure reaching the first entry, the system: determines, based on a non-zero value for the first prefetch region identifier, that the first entry is not available to be allocated; and advances the head pointer to a next entry in the data structure, which renders a load associated with the first entry as a non-blocking load. The system resets the global counter upon completing the one or more instructions.

  • Patent number: 11385872
    Abstract: Operations include a compilation process and a runtime process. A compiler compiles code to generate virtual machine instructions. The compiler further generates information referencing respective parameter types of the parameters of a target virtual machine instruction. The compiler stores the information external to and in association with the target virtual machine instruction. The information may be included in another virtual machine instruction that precedes the target virtual machine instruction. A runtime environment processes the target virtual machine instruction based on the information stored external to and in association with the target virtual machine instruction. Parameter types referenced by the external information override parameter types that are (a) referenced by the target virtual machine instruction itself, (b) deduced by the runtime environment and/or (c) stored directly in association with the parameter values.

  • Patent number: 11361077
    Abstract: A kernel-based proactive engine can be configured to evaluate system call functions that are invoked when user-mode objects make system calls. As part of evaluating a system call function, the kernel-based proactive engine can generate a feature vector for the system call function. The kernel-based proactive engine can then analyze the feature vector using a multidimensional anomaly detection algorithm that has been trained using feature vectors of system call functions that are known to be safe. When the evaluation indicates that the feature vector is anomalous, the kernel-based proactive engine can block the system call.

  • Patent number: 11354267
    Abstract: In an embodiment, a compiler for generating command bundles is configured to receive an execution definition that includes operations for execution. The compiler determines an ordered set of hardware functions corresponding to a hardware architecture to execute at least one operation. The hardware architecture may be selected from typical processor types or a command-aware hardware processor. The compiler generates a command bundle that includes a set of logically independent commands based on hardware functions and functionality of the hardware architecture to optimize execution of the operations. A command-aware hardware processor includes a hardware routing mesh that includes sets of routing nodes that form one or more hardware pipelines. Many hardware pipelines may be included in the hardware routing mesh. A command bundle is transmitted through a selected hardware pipeline via a control path, and is modified by the routing nodes based on execution of commands to achieve a desired outcome.

  • Patent number: 11347518
    Abstract: A system and method for sampling application programming interface (API) execution traces in a computer system uses feature vectors of the API execution traces that are generated using trace-context information. The feature vectors are then used to group the API execution traces into clusters. For the cluster, sampling rates are generated so that a sampling rate is assigned to each of the clusters. The sampling rates are then applied to the API execution traces to adaptively sample the API execution traces based on the clusters to which the API execution traces belong.
