Abstract: A solution for improved monitoring and control of jobs in grid and batch computing systems provides a centralized server's batch manager which is only responsible for workload balancing and job initiation and completion, all other command and status information are communicated directly between the plurality of submitter's systems and the plurality of client systems that are processing their respective workloads. The computing system and communication process utilizes event-driven peer to peer communications between submitter's systems and client systems and enables more detailed status and control information to be passed without overloading the centralized server, and by avoiding polling also provides more immediate feedback of results. Multiple process threads are employed on both the submitter's and client systems, and a user interface consolidates and displays results to the submitter allow commands to be sent to processes running on client batch systems.

Abstract: There is disclosed an inspection device which can be disassembled into a compact configuration permitting it to be moved into and out of the cargo and ballast tanks of an ocean going vessel through the conventional hatches. The invention comprises a carriage support column which is formed by several cables which are stretched vertically between support plates which are temporarily installed on the bottom of the tank or cargo hold and beneath the vessel's decking. A carriage is mounted on the support column for vertical movement thereon, and the carriage preferably carries a remotely controlled drive motor which can rotate the carriage, preferably in a full 360.degree. arc. A remotely controlled television camera and the necessary lights are mounted on the carriage and can be panned around the column to observe and record the visual appearance of the interior structural members.
