摘要： Method, apparatus and system embodiments to schedule user-level OS-independent “shreds” without intervention of an operating system. For at least one embodiment, the shred is scheduled for execution by a scheduler routine rather than the operating system. The scheduler routine may receive compiler-generated hints from a compiler. The compiler hints may be generated by the compiler without user-provided pragmas, and may be passed to the scheduler routine via an API-like interface. The interface may include a scheduling hint data structure that is maintained by the compiler. Other embodiments are also described and claimed.

摘要： Provided are a method, system, and article of manufacture, wherein a plurality of objects are allocated in dynamic memory. Reversed references are determined for the plurality of objects, wherein a reversed reference corresponding to an object is an address of a location that has a valid reference to the object. Unreferenced objects are deleted to fragment the dynamic memory. The fragmented dynamic memory is compacted via adjustments to the reversed references.
摘要翻译：提供了一种方法，系统和制品，其中多个对象被分配在动态存储器中。对于多个对象确定反向引用，其中对应于对象的反向引用是具有对对象的有效引用的位置的地址。删除未引用的对象以对动态内存进行分片。碎片动态存储器通过对反向引用的调整进行压缩。

摘要： A system of permitting stack allocation in a program with open-world features is described. The system includes an escape analysis module to (1) determine which objects of the program can be stack-allocated under a closed-world assumption and (2) analyze, after stack allocation, which stack allocation is invalidated due to the occurrence of an open-world feature. A stack allocation module is provided to stack-allocate these objects based on the determination of the escape analysis module. A stack allocation recovery module is provided to recover those invalidated stack allocations back to their original allocation in heap based on the analysis of the escape analysis module. A method of permitting stack allocation in a program with open-world features is also described.

摘要： A technique includes querying method information in execution environments for programs written for virtual machines. This technique limits the searching scope within a relatively smaller region of the queried instruction pointer (IP) or code address and relieves the management overhead of a method lookup table, with garbage collector facilitation. In one embodiment, a system receives a code address and queries method metadata for the code address by limiting the search scope within a local memory sub-region of the code address.
摘要翻译：一种技术包括在针对虚拟机编写的程序的执行环境中查询方法信息。该技术将搜索范围限制在查询指令指针（IP）或代码地址的相对较小的区域内，并减轻方法查找表的管理开销，并使垃圾回收器便利化。在一个实施例中，系统通过将搜索范围限制在代码地址的本地存储器子区域中来接收代码地址并查询代码地址的方法元数据。
