RAMP: Research Accelerator for Multiple Processors Goal:Invent an infrastructure for cycle- accurate emulators many-core systems using FPGAs Not goals: FPGA computing, gate-level sim Reasons Rapid design space exploration Scalability High confidence on results Early platform for software development

RAMP - Phase 1 The base board: BEE2 The tools: Verilog, RDL, Bluespec The designs: Red, Blue, White Successes Working designs, 2 well attended tutorials, growing team, industrial involvement, … Lessons learned Requirements for new board (BEE3) Advantages and limitations of approaches Prototypes, emulation, co-emulation, … Need for sharing at higher levels Above RTL in a HW-independent manner

This Retreat: Start RAMP Phase 2 The base board: BEE3 Discussion on (Common) targets & tools Infrastructure for sharing Dissemination outside of the core team …

Retreat Etiquette Actively participate in the discussion Lots of scheduled discussion time & breaks Tell us your opinion & ask questions Be open to research ideas Ignore web/ for 1.5 days

Update from 2008 Olympics

Interesting Olympics Facts Olympics medals per capita #7 Saint Kitts & Nevis (256/10m) #9 Bahamas (198/10m) #19 Greece (118/10m) #25 Tonga (78/10m) #28 USA (71/10m) Total medal count since 1912 Games Berkeley: 155 Stanford: 206 Sources: Calbears.com, Gostanford.com

Breakout Topics Potential topics Layered specification of interfaces (lead Joel?) What is our OSI mode equivalent? How do we facilitate sharing at multiple levels? Target functionality & uses (lead James?) Compelling use scenarios for us and other users? Physical implementation (lead Chuck?) Boards, challenges, roadmap, sharing … RAMP as a service Providing online HW platforms & tools (lead Dan?) The update
