摘要： A method includes identifying a code portion that accesses a primitive value in a user-defined function included in a user program, converting the code portion and an argument in a manner to directly reference an internal data representation of the user program, and generating a code for calling the user-defined function converted by the conversion.

摘要： A computer-implemented scaling method, an apparatus, and a computer program product for detecting whether a performance of a system reaches a target performance are provided. The method includes scaling a layered software environment, including scaling a first layer software environment in the layered software environment in response to the performance of the system not reaching the target performance and scaling a second layer software environment that is above the first layer software environment in the layered software environment in response to the performance of the system not reaching the target performance despite the first layer software environment being scaled. The method also includes scaling hardware resources used for executing the layered software environment in the system in response to the performance of the system not reaching the target performance before scaling of the first layer software environment or after scaling of the second layer software environment.

摘要： A thread priority control mechanism is provided which uses the completion event of the preceding transaction to raise the priority of the next transaction in the order of execution when the transaction status has been changed from speculative to non-speculative. In one aspect of the present invention, a thread-level speculation mechanism is provided which has content-addressable memory, an address register and a comparator for recording transaction footprints, and a control logic circuit for supporting memory synchronization instructions. This supports hardware transaction memory in detecting transaction conflicts. This thread-level speculation mechanism includes a priority up bit for recording an attribute operand in a memory synchronization instruction, a means for generating a priority up event when a thread wake-up event has occurred and the priority up bit is 1, and a means for preventing the CAM from storing the load/store address when the instruction is a non-transaction instruction.

摘要： Securing pods in a container orchestration environment is provided. A container runtime interface command is verified to perform an orchestration action on a set of containers comprising an application workload that corresponds to a service based on matching the container runtime interface command to a rule contained in a trusted execution environment contract included in a pod sandbox virtual machine of a trusted execution environment. It is determined whether the container runtime interface command to perform the orchestration action on the set of containers is valid based finding a matching rule in the trusted execution environment contract. In response to determining that the container runtime interface command to perform the orchestration action on the set of containers is valid, the container runtime interface command is executed to perform the orchestration action on the set of containers in the pod sandbox virtual machine of the trusted execution environment.

摘要： A method is provided for building calling context trees of an application to identify a thread or a device affecting a throughput of a transaction relating to the application. The method obtains profiles of call stacks of multiple threads. The method obtains wake-up profiles which are the call stacks of a notifier thread and a waiter thread, from among the multiple threads, in a case that the waiter thread leaves from a sleep state. The method builds the calling context trees to indicate transitions of methods tracing callee relations and wake-up relations based on the profiles of the call stacks and the wake-up profiles, wherein each method is represented by a node having an average thread number. The method extracts and displays tree portions which are transitively reachable from a calling context tree for the transaction and which include the thread or device affecting throughput.
