The Pacific Rim and Grid Middleware Assembly (PRAGMA) is grass roots consortium of more than 20 Pacific Rim institutions. Activities focus on developing, and deploying practical cyberinfrastructure to assist lab-to-lab collaboration for long-tail science communities. Science focus areas include: biodiversity, fresh water ecology, software-defined networking, telescience, education, biosciences, geosciences. PRAGMA defines scientific expeditions where domain scientists and cyberinfrastructure specialists work together over long periods of time to develop solutions that meet the needs of the science but can also be applied more generally. Worked examples, like bringing high-throughput computing to the R-desktop of fresh water ecologists has had the impact of dramatically simplifying access to lake model simulations, will be presented.

This talk will survey the various technology components that PRAGMA has used, evaluated, developed, and where appropriate, discarded. The long time arc (15+ years)of PRAGMA affords a unique perspective the promises, the near-misses, and the successes in the space where technology meets international collaboration.
