Apache OODT is NASA’s first project to be stewarded at the open source Apache Software Foundation. OODT is middleware for information integration and for science data processing and retrieval. It provides components including file management, workflow management, resource management, and automated remote data acquisition, file crawling and ingestion, and science algorithm wrapping and integration. Project [...]
Save is a lightweight framework for creating high availability systems. Save manages IP addresses shared between multiple servers with the same function and monitors the health of those servers to determine which should be actively servicing requests at any given time. Save has additional features to facilitate the administration of high availability systems. Synchronization mechanisms [...]
Mutil is a set of standard utilities that employ multiple types of parallelism and other optimizations to achieve maximum performance on modern file systems. Multi-threading is used to ensure that nodes are kept as busy as possible. Double buffering allows individual operations within a single task to be overlapped using asynchronous I/O. Multi-node cooperation allows [...]
Mesh is a secure, lightweight grid middleware that is based on the addition of a single sign-on capability to the built-in public key authentication mechanism of SSH using system call interposition. Resources may be added to a Mesh-based grid in a matter of minutes using just five small files and two environment variable settings. Mesh [...]
Ballast is a tool for balancing user load across SSH servers based on configurable criteria such as CPU load and system availability. Ballast is invoked as part of the SSH login process, hence has access to the user name, which is not available in traditional load balancers. This gives ballast the unique ability to perform [...]
The Simple, Scalable, Script-based Science Processor for Measurements (S4PM) is a system for highly automated processing of science data, scalable up to large processing systems and scalable down to small, special-purpose processing strings.
ViSBARD (Visual System for Browsing, Analysis, and Retrieval of Data) is an interactive visualization and analysis tool for space physics data. It provides an integrated 3-D/2-D environment to analyze measurements across many spacecraft and MHD models.
The General Mission Analysis Tool (GMAT) is an open-source space mission analysis and design tool being developed by a team made up of NASA, private industry, and a range of academic, public, and private contributors. GMAT is intended both for real-world engineering design studies and as a tool for education and public engagement in the [...]
The Goddard Mission Services Evolution Center (GMSEC) program was established in 2001 to coordinate ground and flight data systems development and services at GSFC with the ultimate goal to efficiently support current and future GSFC mission services. The GMSEC architecture is a ground systems architecture that spans the full mission lifecycle from development through operations. [...]
