    • 19. 19 THE SMALL BATCH SOLUTIONS IN MANTLE API | AUGUST 8, 2014 Lessons Learned
    • 20. 20 THE SMALL BATCH SOLUTIONS IN MANTLE API | AUGUST 8, 2014 Think Outside the Box Don’t just make something faster …avoid doing it completely Design API and driver together
    • 21. 21 THE SMALL BATCH SOLUTIONS IN MANTLE API | AUGUST 8, 2014 New Driver Design Even a bit of sync kills many-core performance “Thick” driver = cache pollution “Make it the application’s problem” 
    • 22. 22 THE SMALL BATCH SOLUTIONS IN MANTLE API | AUGUST 8, 2014 Lots of Little Things… The whole is greater than the sum of its parts
    • 23. 23 THE SMALL BATCH SOLUTIONS IN MANTLE API | AUGUST 8, 2014 Future HW Considerations HW small batch, anyone? Command processing bottlenecks More operations/batches in flight
    • 24. 24 THE SMALL BATCH SOLUTIONS IN MANTLE API | AUGUST 8, 2014 Challenges Programming is harder Ecosystem must change Applications must "do the right thing“
    • 25. 25 THE SMALL BATCH SOLUTIONS IN MANTLE API | AUGUST 8, 2014 Summary Mantle fixes abstraction level Mantle improves platform efficiency Mantle leads industry transformation
