Abstract: An embodiment includes initiating a first cycle of a process using a first number of threads that operate in parallel to collectively execute the process and collect performance data. The embodiment aggregates the performance data and computes a first idle duration based at least in part on the aggregated performance data. The embodiment projects a thread-count recommendation based at least in part on a mathematical model that includes the first number of threads as an input number of threads, the first idle and cycle durations as input idle and cycle durations, respectively, and a second number of threads as an output variable representative of an output number of threads, where the output number of threads is determined as a function of the input idle duration. The embodiment initiates a second cycle of the process using the second number of threads output as a projection by the mathematical model.

Abstract: A first thread of a garbage collector can determine fields, in class metadata assigned to objects contained in a local memory, that are self-referencing fields. For a plurality of the objects, recursively, the first thread can determine whether the object has at least one child object, indicated by a self-referencing field of the object, that has not been assigned to a destination cache or a previously generated source cache. If so, the first thread can assign the child object to the destination cache to indicate that the child object is live. The first thread can add the destination cache to a global scan queue as a source cache. A second thread of the garbage collector can initiate object scanning on objects indicated in the first source cache. Memory locations where live objects are not located can be reclaimed.
