11 Multicore CPUs vs GPUs vs Manycore Control ALU ALU ALU ALU Cache DRAM CPU GPU Manycore CPU are optimized for sequential code performance Sophisiticated Control Logic to execute several instruction at the same time Very large cache to reduce access time to instruction and data of complex applications Clock frequency limits reached long ago 50 to 150 Watt CONSTRAINED BY Power consumption, Complexity, Scalability Originates from the video game industry Very simple control units and huge number of floating point units working in parallel SIMD processing model Smaller cache than CPUs 20 to 300 Watt CONSTRAINED BY Power consumption, Programming model, Communication overhead Rich CPU-like Control units + FPU Cluster of processors share a local memory Clusters communicate through a high speed low latency network on chip MIMD paradigm (Multiple instructions Multiple Data) rather than MIMD 5 to 10 Watt CONSTRAINED BY Disruptive technology adoption curve 2013 Kalray SA All Rights Reserved Confidential Information 13

13 Manycore opportunities in Big Data
14 Be more efficient remotely Computing efficiency (GFlops/Watt) Energy consumption becomes an absolute barrier whether in high-end embedded sytems or data-centers Hardware efficiency (GFlops/$) Remove unnecessary hardware overhead Bandwidth (MB/s) Bring data in and out fast and avoid bus bottleneck 2013 Kalray SA All Rights Reserved Confidential Information 17
15 Do more locally Process data at the source Bring more intelligence right next to the data generator Imperatives : more Gflop/W and Gflop/$ Use new «online» information processing models Learn from data and predict continuously and in real time (e.g. HTM/CLA) Benefits Save on the global system cost (e.g. lighter network infrastructure) Save on energy : transmitting and processing date remotely takes 100 to 1000 times more energy than doing it locally Adapt local acquisition and screening strategies 2013 Kalray SA All Rights Reserved Confidential Information 18
