NASA's mission crilical Hubble Space Telescope (HST) command and control system has been re-engineered x,_th commercial-off-theshelffgovernment-off-the-shelf (COTS/GOTS)and minimal custom code. This paper focuses on the design of this new HST Control Center System (CCS) and the lessc41s learned throughout its development. CCS currently utilizes more than 30 COTS/GOTS products with an additional...

Since all Department of Defense (DoD) missions depend on cyber assets and capabilities, a dynamic and accurate cyber dependency analysis is a critical component of mission assurance. Mission analysis aims to identify hosts and applications that are “mission critical” so they can be monitored, and resources preferentially allocated to mitigate risks. For missions limited in duration and scale (t...

OpenMP lacks essential features for developing mission-critical software. In particular, it has no support for detecting and handling errors or even a concept of them. In this paper, the OpenMP Error Model Subcommittee reports on solutions under consideration for this major omission. We identify issues with the current OpenMP specification and propose a path to extend OpenMP with error-handling...

Any books that you read, no matter how you got the sentences that have been read from the books, surely they will give you goodness. But, we will show you one of recommendation of the book that you need to read. This design and analysis of accelerated tests for mission critical reliability is what we surely mean. We will show you the reasonable reasons why you need to read this book. This book ...

Within the Department of Defense (DoD), mission-critical software maintenance has been reported to cost between $700 million and $20 billion annually. The wide range of estimates results from uncertainty over the definitions of “mission-critical” and “software maintenance” as well as the lack of any catalog of performing activities. The problem is deeper than definitions and level of investment...

The Network Time Protocol (NTP) is used in networks of all types and sizes for time synchronization of servers, workstations, and other networked equipment. As time synchronization is more and more a mission-critical service, standardized means for monitoring and management of this subsystem of a networked host are required to allow operators of such a service to set up a monitoring system that...
