4 cFS Workshop Goals Discuss current informal community charter/organization and create a roadmap for establishing a formal charter Get feedback from user community to understand their perspectives, needs, and goals Describe current product management, identify needs, and create a plan forward Describe current communication mechanisms, shortcomings, and create a plan forward Provide path for how to engage and grow the community -Introduce virtual teams Reduce risk of fragmentation!!

5 cFS Workshop Strategy Agenda flow -Where are we now? -Where do we want to be? -How can we get there? Gary Smith is our workshop administrative officer -Take notes and log action items -Inputs via sign up sheets or Compile attendance list: Name, Organization, Location (APL or remote) Virtual team sign up Accept general comments Gary and I will organize the programmatic/technical information to help facilitate our final session of the workshop

6 Before we begin… Questions, suggestions, etc. There are 10 types of people in the world: those who understand binary, and those who don't

8 Agenda Community -Background -Current state -Next steps Virtual Teams Website Proposal User Scenarios

9 Background < 2007: Birth of core Flight Executive (cFE) -GSFC assessment of FSW reuse to date, heritage analysis, architectural trades -Project independent funding kick started the effort -Operating System Abstraction Layer (OSAL) released as open source 2007: cFE goes to the Moon -LRO launched using OSAL & cFE 2008 – 2014: Birth of core Flight System (cFS) -Developed 12 cFS applications -Leveraged project funding -JSC certified Class A pedigree of cFS targeted to the ARINC : Birth of a Community -12 cFS applications released as open source -cFS Workshop (12/15 at GRC) established a NASA-wide repository managed by an inter-center Configuration Control Board (CCB) 2015: Community is growing up -Successful release of cFE cFE API is unchanged since LRO -First cFS Workshop

10 cFS Community Purpose Advance the creation, evolution, promotion, and support of a NASA Class B flight software system -Important we stay focused on our domain Cultivate both an open source community and an ecosystem of complementary products, capabilities, and services. -All inclusive in terms of organizations -No constraints on complementary products

11 State of the Community Business Model Funding Model -No institutional funding, Advanced Exploration Systems (JSC) provides a lifeline -Members use ‘local’ funding to support community activities -New release content driven by upcoming member mission needs No formal community charter, by-laws, or operating procedures in place -Original 2012 draft charter never signed -Some original concepts still valid, but top-down funding approach needs rework Product Management is evolving and a management plan needs to be defined to cover -Scope of products controlled by the CCB -Product release strategies and versioning -Product delivery and community feedback

12 State of the Community Communication Mailing Lists Contains all members CCB members Public Websites - General information and links to all open source code and documents on Sourceforge - Multiple projects for different cFS components Restricted access (requires NDC account) - NESC hosted server containing discussion forums, documents, meeting notes… Approved for ITAR and Sensitive But Unclassified (SBU) material - ARC hosted server used for inter-center collaboration Git andTrac used for source code configuration management and change requests Not approved for ITAR material

13 A Few Realities… ITAR (International Traffic in Arms Regulations) and the EAR (Export Administration Regulations) -Export control regulations -Recent ITAR changes have moved some space related items from the U.S. Munitions List (USMAL) to the Commerce Control List (CCL) NASA Software Engineering Requirements, NPR B (11/19/14 – 11/19/19) -Establishes the engineering requirements for software acquisition, development, maintenance, retirement, operations, and management consistent with the governance model contained in NASA Policy Directive (NPD) , NASA Governance and Strategic Management Handbook. This NASA Procedural Requirements (NPR) supports the implementation of the NASA Policy Directive (NPD) Release of NASA Software, NPR C (expired 8/11/15) -Establishes procedures and responsibilities for the reporting, review, assessment, and release of software created by or for NASA Inventions Made By Government Employees, NPD B (4/21/08 – 4/21/18) -Civil servant or contractors receiving research and development funding are required to report their findings to the Technology Transfer Office

15 cFS Community The power of a community -1993, 2001, 2009 NASA Controlled Assets (NCA) -Assets managed by the NASA CCB -Architectural in nature -Maintained in accordance with NPR B Class B requirements Member Sponsored Assets (MSA) -Developed and released by a community member -No NPR B requirements -NASA projects would need MSA process to migrate assets to be used on a NASA mission Formalize charter and operational procedures -Mature draft plan and create a plan to get it signed -Steering committee (could be subset of CCB) that meets regularly (quarterly) to mange strategic direction

16 Virtual Teams Groups of people aligned with a common interest -E.g. Multicore processors, Xenomai, Electronic Data Sheets Two types -Integrated Team: Organized as a project -Cooperative: Parallel teams that maintain communication Challenges -Funding source(s) may not agree with producing cFS assets in addition to their own goals. “Think global, act local” doesn’t work in every situation. -Restrictions on sharing information -Aligning teams with NASA Controlled Asset deliverables

17 Virtual Team Topic Area - Architecture Multicore, Partitioned Systems, Memory Protection Software Bus Network Driver Plugins Libraries Non-volatile configurations, EEPROM File System (EEFS) Security

18 Virtual Teams Topic Area - Tools Deployment, Configuration Parameter profiles Automated unit testing Platform-independent build testing Application Certification Electronic Data Sheets Code Generation: Simulink Interface Layer Benchmarks Integrated Development Environment Ground systems

19 Virtual Team Topic Area - Communication Website Training courses Promotional material Business case material Outreach & Education -Learning platforms: Quadcopter, PiSat, …

20 Website Proposal The University of Florida’s Center for High-Performance Reconfigurable Computing (CHREC offered to host a cFS websitehttp:// -Initial discussions have defined needs and potential solutions -This workshop can be used help refine ideas Evolutionary approach -Create document repository and discussion forum -Create infrastructure for member sponsored products and collaborative projects -Create infrastructure for NASA controlled products Target a ‘go live’ date after the 12/15 cFE delivery (Early 2016)

21 User Scenarios Identify and prioritize user scenarios that need to be supported by the community 1.Obtain and build the cFS -Locate product and follow instructions -Ask questions 2.Configure and target the cFS to a platform -Learn whether desired target has been done before -Get training 3.Submit a trouble ticket 4.Make a contribution back to a product: NASA or user sponsored 5.Obtain a list of outstanding tickets 6.Get information on future release plans 7.Submit a Member Sponsored Artifact 8.Form a virtual team 9.Create a collaboration project
