Abstract: A method of producing an executable image from an object file without shared library support from the operating system, wherein the executable image requires a shared library file in order to resolve at least one of the symbols called for in the object file. A method of optimizing the loading of a previously linked file into working memory in a computer for executing in a single address space of the working memory, the file containing an instruction to make an indirect jump to a location in a shared library through an import section of the file. A method for optimizing the loading of a previously linked file into working memory in a computer for executing in a single address space of the working memory, the file containing plural sections with number-filled padding between the end of each section and a succeeding page boundary. A method of optimizing the loading of a previously linked file into working memory in a computer for executing in a memory sharable with other executables.

Abstract: The present invention is directed to a loadable virtual memory manager, and generally to a computer operating system capable of supporting application programs running in a computer having a working memory, the computer operating system including a kernel resident in the working memory at run time, and a loadable virtual memory manager resident at link time outside of the working memory and dynamically loadable into the working memory at run time upon demand of one of the application programs. The kernel includes a loader for loading the virtual memory manager into the working memory in response to a demand from one of the application programs. The computer is able to access a storage memory separate from the working memory, the loadable virtual memory manager residing at link time in the storage memory. The loader loads the virtual memory manager from the storage memory to the working memory.

Abstract: A method and system for managing the execution of threads uses a single scheduler for both threads and work items. Objects representing the threads and the work items are either maintained in separate queues or are stored together in a single queue. Each thread object or work item object may contain information that allows the scheduler to determine what order to execute the corresponding threads or to process the corresponding work items.

Abstract: In accordance with another aspect, the invention is embodied in a computer operating system capable of supporting plural objects running in a computer having a working memory, the computer operating system including a kernel resident in the working memory at link time, and a loadable mutation object resident at link time outside of the working memory and dynamically loadable into the working memory at run time upon demand of one of the application programs, the mutation object including an interface with methods for mutating any one of the plural objects. The kernel includes a loader for loading the mutation object into the working memory in response to a demand from one of the plural objects. The computer further includes a storage memory separate from the working memory, the loadable mutation object residing at link time in the storage memory.

Abstract: The invention is embodied in software executable on a computer having a working memory with demand-loadable components initially stored outside of the working memory, each component having an entry point including a constructor for an object. Preferably, the demand-loadable components are initially provided in a memory within the computer or a location external of the computer. A Namespace in the working memory provides access in the working memory to the components as they become needed by applications running in the computer. The Namespace provides the access by managing demand-loading and unloading of the components in the working memory.
