Justin Rattner Multi Many Core IDF 2011
<p>Justin Rattner  Multi Many Core IDF 2011
my summary of his video  (delivered this speech on Sept 15 2011)
Intel Core Duo was just intro at IDF in 2006.
Multi core (prob < 10)  up to many core 10+ .
2006  was 2 core
2007  4 core
2010   6-8 core
2011+  10+ cores.
Not all cores r necessar the same... eg  gpu cores;
Knights Ferry.
2011:   many integrated cores = MIC =  MIKE.
he starts with LHC guy from Geneva:  v data intensive  analysis of their on-going data...
they generate petabytes of data.
they use 250,000  Intel cores simult.   to analyze their data  (spread across several centers)
*
Justin Rattner = JR;   u do not need a Ninja Programmer;
move entire DB into RAM... get 100X speedup and 1/1000 the latency.
48 cores in the rack...   1M queries per second.  Billy Cox.
Web Applications:  Queries to a server.
Client Side:  Brendon Ike... inventor of Mozilla  he created Javascript.
SELF and SCHEME...  evolved into  Javascript... most popular language
a corner stone of webapp development.
Tatiana...   dust...  River Trail...   image processing, voice processing
presents parallel extensions for Javascript.
Wireless Base Station...  build it out of PCs.
LTE phone.  China Mobile...
SECURITY on personal computer;  Dave;
it decrypts Justin and then knows which
images to decrypt... each image has a policy
associated with it.
Extreme Scal Computing
20 picojoules per FLOPS in 10 years.
Want a 300X drop in energy usage in 10 years.
20 MWatts for a 1 Exaflop computer.  (Shaker Borkar is presenter)
today a petaflops computer burns   5-10 MWatts...
so, cannot simply scale up by 1000 (would be   10 gigawatts  (buy everyone a nuclear reactor)
Today for a 100 GFlops system (eg Intel Xeon System)
requires 200 Watts
What we want by 2018 is to lower the power . down to 2 WATTS  (EXTREME SCALE 100 GFlops system)
To get there:  need to reduce transistors to NEAR THRESHOLD... eg   run it off the
postage stamp  solar cell.   
want dynamic range....   ie ramp up performance when it is needed.
Sriram  does the demo.
Memory:  hybrid memory cube...  stacks of DRAM...   terabit per second...
perforance  AND  energy effic.
need fine grain power mgmt; self-aware mgmt;
TOMORROW Project
theater of tomorrow:
science fiction, thot leaders;
brian david johnson... resident futurist.
20 mins to count every star in the universe.

The Tomorrow Project
invite u all to join the conversation.</p>
