Virtual software machine running multiple program modules in a single address space of a target computer
TLDR
In this paper, the authors present an enhanced virtual software machine that provides a virtual execution environment in a target computer for application software programs having execution dependencies incompatible with a software execution environment on the target computer.Abstract:
An enhanced virtual software machine that provides a virtual execution environment in a target computer for application software programs having execution dependencies incompatible with a software execution environment on the target computer. The machine comprises a plurality of independent processes, a management interface for generating requests for execution to the plurality of independent processes and receiving results of such processing, and a preprocessor for generating a set of native executable program modules. According to one embodiment, the virtual software machine binds a task manager control module into a single address space of the target computer operating system for each user that attaches to the system. Upon receipt of a transaction request, a dynamic binding facility dynamically binds one or more of the program modules into the single address space for scheduling and execution under the control of the task manager control module. At least one of the program modules calls the management interface upon encountering an execution dependency in the program module and effects the required functionality using an independent process. A task management library is also bound in the single address space and functions to preserve, release and/or restore a context of each of the one or more program modules loading into the single address space during execution of the program modules by the task manager control module.read more

Object-oriented operating system
Debra L. Orton,Eugenie Lee Bolton,Daniel F. Chernikoff,David B. Goldsmith,Christopher P. Moeller +4 more
TL;DR: In this article, an apparatus for enabling an object-oriented application to access in an objectoriented manner a procedural operating system having a native procedural interface is described. But this apparatus is limited to a single application and it is not suitable for multi-object-oriented applications.

Snapshot restore of application chains and applications
Abstract: The present invention saves all process state, memory, and dependencies related to a software application to a snapshot image. Interprocess communication (IPC) mechanisms such as shared memory and semaphores must be preserved in the snapshot image as well. IPC mechanisms include any resource that is shared between two process or any communication mechanism or channel that allow two processes to communicate or interoperate is a form of IPC. Between snapshots, memory deltas are flushed to the snapshot image, so that only the modified-pages need be updated. Software modules are included to track usage of resources and their corresponding handles. At snapshot time, state is saved by querying the operating system kernel, the application snapshot/restore framework components, and the process management subsystem that allows applications to retrieve internal process-specific information not available through existing system calls. At restore time, the reverse sequence of steps for the snapshot procedure is followed and state is restored by making requests to the kernel, the application snapshot/restore framework, and the process management subsystem.

Heterogeneous symmetric multi-processing system
TL;DR: In this article, a heterogeneous symmetric multi-processing system (HMS) is presented, where processors from distinct families of processors are integrated on a single platform. The processors are coupled to an implementation specific communication mechanism through family specific bus interface converters.

Computer integration system
TL;DR: In this article, an update capturing module installed at each computer system, for capturing update transactions involving shared data entities, and a central data translator, which receives the updates from the update capturing modules, translates the updates into appropriate record formats and data base schemas, and transmits the translated replicas to the appropriate separate computer systems, where the updates are directly or indirectly entered into the corresponding data bases, thereby ensuring consistency among separate but related data bases.

Task control manager
TL;DR: In this paper, a plurality of tasks are operated on by providing a start instruction for the execution of tasks, identifying a first task to be started by said start instruction, initiating the first task by the start instruction and initiating the second task before the first one is complete.
