Abstract: A thread management process where a storage area template is generated for a plurality of threads that are to be created by a process in a computing system, the storage area template comprising at least one module template for at least one library that is to be loaded by the process. In the computing system, a plurality of storage areas is allocated for the plurality of threads based on the storage area template, respectively. The plurality of threads are managed based on the plurality of storage areas, respectively. All threads and libraries may be managed in a uniform way according to the storage area template. Therefore, thread management may be simplified and then may lead to reduced costs in the storage and time resources.

Abstract: Techniques for signal handling between programs associated with different addressing modes in a computer system are described herein. An aspect includes, based on a signal occurring during execution of a first program in a first runtime environment, wherein the first program and the first runtime environment are associated with a first addressing mode, invoking a first signal exit routine associated with the first addressing mode. Another aspect includes allocating a signal information area (SIA) by the first signal exit routine. Another aspect includes calling a second signal exit routine associated with a second addressing mode that is different from the first addressing mode with an address of the SIA. Another aspect includes allocating a mirror SIA by the second signal exit routine. Another aspect includes handling the signal, and resuming execution based on the handling of the signal.

Abstract: Aspects of the present disclosure are directed to methods, systems, and computer program products for using dynamic-link library based on memory size. In the method, a request for calling a first function in a Dynamic-link library (DLL) at runtime is received first. A size of a memory allocated to the DLL is then determined. Then call relationship of functions in the DLL is obtained. At last, functions related to the first function in the DLL are loaded into the memory allocated to the DLL based on the size of the memory allocated to the DLL and call relationship of functions in the DLL.

Abstract: Generating a scalable code division and workflow chart. Based on definition-and-use cases of variables in a code snippet to be represented by a graph, crossing references to the variables in the code are determined, where a crossing reference associated with a statement involves a definition of the variable before the statement and a use of the variable at or after the statement. The code snippet is divided, based on the crossing references.

Abstract: A computer-implemented method includes performing, by each of a plurality of crawlers, a random walk of a plurality of objects in a heap, where the plurality of objects are memory objects allocated for execution of an application. A timestamp of each object of the plurality of objects is updated, when the object is visited by a crawler of the plurality of crawlers. Garbage is identified, by a computer processor, based at least in part on the timestamp of each object of the plurality of objects. The garbage is reclaimed.

Abstract: Mechanisms are provided for collecting telemetry data from an observability tool of a container executing on a host computing system. The mechanisms configure a shared memory to implement a telemetry data buffer. The telemetry data buffer is shared by observability tool instances of a plurality of containers on one or more host computing systems. Observability tool instance(s) collect telemetry data from a corresponding container in the plurality of containers. The collected telemetry data is written to a record in the telemetry data buffer. A backend computing system accesses the records in the telemetry data buffer to apply analytics to the telemetry data.
