The LHC produces 600 million collisions every second in each detector, which generates approximately one petabyte of data per second. None of today's computing systems are capable of recording such rates. Hence sophisticated selection systems are used for a first fast electronic pre-selection, only passing one out of 10 000 events. Tens of thousands of processor cores then select 1% of the remaining events. Even after such a drastic data reduction, the four big experiments, ALICE, ATLAS, CMS and LHCb, together need to store over 25 petabytes per year. The LHC data are aggregated in the CERN Data Centre, where initial data reconstruction is performed, and a copy is archived to long-term tape storage. Another copy is sent to several large scale data centres around the world. Subsequently hundreds of thousands of computers from around the world come into action: harnessed in a distributed computing service, they form the Worldwide LHC Computing Grid (WLCG), which provides the resources to store, distribute, and process the LHC data. WLCG combines the power of more than 170 collaborating centres in 36 countries around the world, which are linked to CERN. Every day WLCG processes more than 1.5 million 'jobs', corresponding to a single computer running for more than 600 years.

@rylanconway6378
@rylanconway6378 8 жыл бұрын
+herpsenderpsen The magnets are precise but not that precise. We are able to get reliable collision rates by bunching the protons/heavy-ions into bunches containing ~100 billion protons each. When you smash a blob of 100 billion protons into another blob of 100 billion protons you're going to end up with collisions. Now, most of these collisions are glancing collisions where nothing really interesting happens and that is exactly why the first step in LHC data processing is filtering out these collisions.

i would have thought they stored way more than 25 petabytes a year in data, especially with the amount produced. If I recall correctly they only keep data that is "interesting" or different from a typical collision. As a network engineer 25 petabytes just doesn't seem like that much information.
@herpsenderpsen
@herpsenderpsen 8 жыл бұрын
+fckth3systm I think there's a lot of raw data there that's just "junk" for them, aka not interesting. I guess the real job is finding something interesting amongst all the data and then actually figuring out what the data represents.

There is way too much data to store it all on SSD. That would be far too expensive. Tape is slow, but is still the cheapest per byte. They have a lot of data to handle.

Why is Africa always left out in the scheme? Just look at how Africa is left out of the grid. It is clear we are marginalized not because we are not that intelligent but because of stereotype. There is a sense of being left out in this project for young African like me.

Ralph Walters True, but they are funding the LHC through their country’s financial and academic contributions. Personally, I crave more information (or at least as much as I can fathom!) about the sciences but many are turned off by the subject. I think this “marketing” type video is really well produced, clear and helps laypeople to understand what’s achieved there.
