Industry Challenges Before Us
• Rebuild the computer ecosystem
• Rewrite billions of lines of code
• Re-educate millions of programmers
• Rewrite the education curriculum

Any Reason to Think the Future of Computing is NOT Parallel?
What is Parallella?

“A $99 credit card sized parallel computing platform”
Parallella Principles
13
• PARALLEL: • Heterogeneous and scalable parallel hardware
• OPEN: • Open source O/S (Linux) • Open chip documentation • Open source drivers and SDK • Open source hardware (board schematics, docs, layout) • Open standards (OpenCL, OpenMP, MPI, ...)
• ACESSIBLE: • $99 starting point • Easy to use novice progammers
Parallella Kickstarter Stats
14
• ”$99 Linux supercomputer” • 5,000 backers • 6,300 boards ”pre-sold” in 4 weeks • 67 countries, all 50 US states • 50-75% of backers are developers • 5,000 more signups since Jan 1st • Customer Application Classes:
• SDR (GNU Radio) • Ray tracing/rendering • Image processing • Robotics • Gaming
• Cryptography • Media Server • Distributed Computing • Signal processing • HPC
