A B O U T   the Computational Infrastructure
The Computational Infrastructure for Nuclear Astrophysics (CINA) is a cloud computing system that enables researchers to: calculate thermonuclear reaction rates from nuclear physics input; create and manage customized rate libraries; modify & visualize rates; set up, execute, and visualize element synthesis calculations; and share work with other Users in an online community.

Some of the main features of CINA include:

• work with nuclear information, thermonuclear reaction rates, and simulations
• operates "in the cloud" – you need an internet connection
• forms a "virtual pipeline" to process laboratory results into astrophysical predictions
• upload your information (cross sections, rates ...), process it, use in simulations
• save your work on our server, quickly share with other Users
• graphical user interface (GUI) is a platform-independent java application
• easy-to-follow GUI simplifies complex manipulations and tasks
• automated studies of the sensitivity of simulations to reaction rate input
• post-processing nucleosynthesis simulations for main sequence (pp, CNO), novae (Hot CNO, rp-process), X-ray bursts (Hot CNO, alpha-p process, rp-process), supernovae (r-process)
• nucleosynthesis "engine" is XNET code maintained by W.R. Hix
• default reaction rate library -- JINA REACLIB v2.0 -- can be customized with your latest rates
• system online since 2004 with Users from 126 institutions in 29 countries
• new features are added at request of Users
• registered Users get free disk space on our server and access to all functions
• sample investigations available that are appropriate for high school, college, and graduate school students
