Douglas C. SchmidtAs part of an ongoing effort to keep you informed about our latest work, I would like to let you know about some recently published SEI technical reports and notes. These reports highlight the latest work of SEI technologists in resilience, metrics, sustainment, and software assurance. This post includes a listing of each report, author(s), and links where the published reports can be accessed on the SEI website.

Can’t Buy Me DevOps

This post is the latest installment in a series aimed at helping organizations adopt DevOps.

Aaron VolkmannThe DevOps movement is clearly taking the IT world by storm. Technical feats, such as continuous integration (CI), comprehensive automated testing, and continuous delivery (CD) that at one time could only be mastered by hip, trendy startups incapable of failure, are now being successfully performed by traditional enterprises who have a long history of IT operations and are still relying on legacy technologies (the former type of enterprises are known in the DevOps community as “unicorns,” the latter as “horses”). In this post, I explore the experience of a fictional horse, Derrick and Anderson (D&A) Lumber, Inc., a company that hit some bumps in the road on its way to DevOps. As D&A finds out, a DevOps transformation is not a product that can be purchased from the outside, but rather a competency that must be grown from within.

Kevin FallThe Department of Defense (DoD) and other government agencies increasingly rely on software and networked software systems. As one of over 40 federally funded research and development centers sponsored by the United States government, Carnegie Mellon University’s Software Engineering Institute (SEI) is working to help the government acquire, design, produce, and evolve software-reliant systems in an affordable and secure manner. The quality, safety, reliability, and security of software and the cyberspace it creates are major concerns for both embedded systems and enterprise systems employed for information processing tasks in health care, homeland security, intelligence, logistics, etc. Cybersecurity risks, a primary focus area of the SEI’s CERT Division, regularly appear in news media and have resulted in policy action at the highest levels of the US government (See Report to the President: Immediate Opportunities for Strengthening the Nation’s Cybersecurity ). This blog posting is the first in a series describing the SEI’s five-year technical strategic plan, which aims to equip the government with the best combination of thinking, technology, and methods to address its software and cybersecurity challenges.

This post is the latest installment in a series aimed at helping organizations adopt DevOps.

Aaron VolkmannWhen building and delivering software, DevOps practices, such as automated testing, continuous integration, and continuous delivery, allow organizations to move more quickly by speeding the delivery of quality software features, that increase business value. Infrastructure automation tools, such as Chef, Puppet, and Ansible, allow the application of these practices to compute nodes through server provisioning using software scripts. These scripts are first-class software artifacts that benefit from source code version control, automated testing, continuous integration, and continuous delivery.

Developing a Software Library for Graph Analytics

This blog post was co-authored by Eric Werner.

Scott McMillanGraph algorithms are in wide use in Department of Defense (DoD) software applications, including intelligence analysis, autonomous systems, cyber intelligence and security, and logistics optimizations. In late 2013, several luminaries from the graph analytics community released a position paper calling for an open effort, now referred to as GraphBLAS, to define a standard for graph algorithms in terms of linear algebraic operations. BLAS stands for Basic Linear Algebra Subprograms and is a common library specification used in scientific computation. The authors of the position paper propose extending the National Institute of Standards and Technology’s Sparse Basic Linear Algebra Subprograms (spBLAS) library to perform graph computations. The position paper served as the latest catalyst for the ongoing research by the SEI’s Emerging Technology Center in the field of graph algorithms and heterogeneous high-performance computing (HHPC). This blog post, the second in our series, describes our efforts to create a software library of graph algorithms for heterogeneous architectures that will be released via open source.
