Abstract: Systems and methods for processing hierarchical tasks in a garbage collection mechanism are provided. The method includes determining chunks in a task queue. Each chunk is a group of child tasks created after processing one task. The method includes popping, by an owner thread, tasks from a top side of the task queue pointed at by a chunk in a first in first out (FIFO) pop. The method also includes stealing, by a thief thread, tasks from a chunk in an opposite side of the task queue.

Abstract: A computer-implemented method is provided for managing Garbage Collection (GC) safepoints. The method includes determining whether a GC safepoint for a target native method can be removed by checking a heap occupancy ratio prior to executing the target native method. The method further includes removing the GC safepoint responsive to the heap occupancy ratio prior to executing the target native method being less than a threshold occupancy amount percentage. The method also includes determining whether the GC safepoint for the target native method can be removed by checking a most recent GC pause time. The method additionally includes removing the GC safepoint responsive to the most recent GC pause time being shorter by a threshold pause time amount percentage than an execution time of the target native method.

Abstract: A physical three-dimensional (3D) model is printed that corresponds to a 3D digital design of an underlying digital render model of an object.

Abstract: A computer-implemented method is presented for reducing data loading overhead of middleware to facilitate direct data loading to a database management system (DBMS). The method includes, while data loading, sending external-writes to a memory-based DBMS if corresponding internal-writes are for vertices, exporting all the external-writes to a disk-based DBMS as an export file, and sending an external-read for vertices to an in-memory DBMS if the middleware requests data. The method further includes, at the end of data loading, generating files for raw data of the disk-based DBMS from the export file and sending the generated raw files to the disk-based DBMS.
