Filed:

Jun 7, 1995

Appl. No.:

8/483783

Inventors:

Eric R. Carpenter - Round Rock TX
Christopher S. Claussen - Austin TX
James O. Cox - Austin TX

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 15163

US Classification:

39520003

Abstract:

A method and system for providing communications services between multiple processes running in multiple computer systems is provided. A single system semantic can be used to access processes, whether such processes reside on a local or remote computer. A mechanism is provided to allow processes to register as part of a distributed context. Registration may be accomplished explicitly by any child process to name its parent in the hierarchy, or automatically by the parent process when spawning children. This mechanism allows the additional flexibility that destination nodes in the distributed environment may be selected at run time without requiring knowledge on the part of the executing process. This allows the ability to cause processes to be distributed based on machine type, facilities available on a specific node or load balancing considerations. This registration mechanism is expandable to allow general purpose server implementations in a distributed environment, thus providing to the user system transparent facilities for control in a distributed environment.

Abstract:

Disclosed is a method and system for providing a complex testing framework/scaffold. Also included are testing tools that automate and simplify the testing process. The disclosed design handles networking and task concurrency. The testing scaffold is aimed at being a flexible test case driver that can be used to execute functional verification tests on a single host or large networked system level integration tests involving dozens of hosts. The testing scaffold is designed to meet the requirements of large scale testing environments. The ability to execute these environments similarly allows manipulation of smaller scale environments.
