摘要： An integrated software architecture for a highly parallel multiprocessor system having multiple tightly-coupled processors that share a common memory efficiently controls the interface with and execution of programs on such a multiprocessor system. The software architecture combines a symmetrically integrated multithreaded operating system and an integrated parallel user environment. The operating system distributively implements an anarchy-based scheduling model for the scheduling of processes and resources by allowing each processor to access a single image of the operating system stored in the common memory that operates on a common set of operating system shared resources. The user environment provides a common visual representation for a plurality of program development tools that provide compilation, execution and debugging capabilities for multithreaded user programs and assumes parallelism as the standard mode of operation.

摘要： A modular compilation system that utilizes a fully integrated hierarchical representation as a common intermediate representation to compile source code programs written in one or more procedural programming languages into an executable object code file. The structure of the integrated common intermediate representation supports machine-independent optimizations, as well as machine-dependent optimizations, and also supports source-level debugging of the executable object code file. The integrated hierarchical representation (IHR) is language independent and is shared by all of the components of the software development system, including the debugger.

摘要： On a tightly coupled multiprocessor computer system, the multiple parallel regions of a multithreaded applications program can execute simultaneously as multiple threads on a plurality of processors. Furthermore, a plurality of multithreaded programs may run simultaneously. The current invention uses an efficient system to schedule and reschedule processors to run these multiple threads. Scheduling is integrated at two levels: at the first level, processors are assigned processes. At the next level, processes are assigned threads. Increased efficiency is achieved by this integration and also by the formation of processes with destructible context. It makes use of shared storage to indicate the process request level and the control state for each parallel region.

摘要： A system and method for providing a distributed debugger system for a distributed target computer application are disclosed wherein the programmer/developer of the application can be at one host machine and wherein the application being developed makes use of objects and object implementations which may be located on a different host machine which is unknown to the programmer/developer. The system and method provides solutions to problems which are encountered in trying to debug a new application which is associated with the use of objects in a widely distributed, object oriented, client-server system. In a distributed object environment, requests and replies are made through an Object Request Broker (ORB) that is aware of the locations and status of objects. One architecture which is suitable for implementing such an ORB is provided by the Common Object Request Broker Architecture (CORBA) specification. The distributed debugger system disclosed herein is designed to function in a CORBA compliant distributed system.

摘要： A heap may be marked and compacted while performing only two passes over the objects and object references in the heap. Specifically, objects and object references are traversed once during a marking phase and again during a compaction phase of split-reference, two-pass mark-compaction. Object references are updated in two steps. First, during marking, each object reference may be updated to include the relative offset within its block of the referenced object and-during compaction that offset may be added to the block's destination address resulting in a reference that points to the actual post-compaction location for the referenced object. Objects of a particular block may be rearranged, or permuted, with respect to each other within the block. However, the order between groups of objects in different blocks may be preserved across compaction.
摘要翻译：堆可以被标记和压缩，同时仅在堆中的对象和对象引用执行两次传递。具体来说，在标记阶段期间遍历一次对象和对象引用，并在分割参考，二次标记压缩的压缩阶段再次遍历对象和对象引用。对象引用有两个步骤更新。首先，在标记期间，可以更新每个对象引用以包括其引用对象的块内的相对偏移量，并且 - 在压缩期间，该偏移可以被添加到块的目的地地址，导致指向实际的后压缩位置的引用为引用的对象。特定块的对象可以在块内相对于彼此重新布置或排列。但是，不同块中的对象组之间的顺序可以在压缩之间保留。
