Cell/B.E. Recap
What is the Cell Broadband Engine?Pioneered by Sony, Toshiba, IBM‘Many-Core’ processor1 PPE Processor8 SPE ‘SIMD Monsters’
PPE (PPU) is a scaler proc
SPEs (SPUs) are vector or array procs
CONFIDENTIAL
Cell/B.E. Recap
230GFLOPS by 9 processing elements
Synergistic Processor Element
Jointly developed by Sony, Toshiba, and IBM
FLEX I/O20GB/s

Where is the Cell?
Look in your kids’ rooms
…or next to your HDTV!
PS3 Clusters are also in high demand
for their compelling price/performance. Folding@home, Black Hole Research, Ray-Tracing, Modelling, etc

Roadrunner –116,640 Cell Cores1st Supercomputer to Sustain 1 petaflop/s
“The Los Alamos system, nicknamed Roadrunner… fended off a challenge by the Cray XT5 supercomputer at Oak Ridge National Laboratory called Jaguar.
The system, only the second to break the petaflop/s barrier, posted a top performance of 1.059 petaflop/s in running the Linpack benchmark application. One petaflop/s represents one quadrillion floating point operations per second.“
petaFLOPS = 1015

RAM: - Far from cores (poor latency) - Goes thru NB (low bandwidth)
RAM: - Next to cores (better latency) - Directly to RAM (better bandwidth)

AMD
Almost same as AMD HT architecture.Wider bandwidthLower latency
This was the reason why many people selected AMD Opteron.
