A Look At CERN's LHC Grid-Computing Architecture

blair1q writes "Using a four-tiered architecture (from CERN's central computer at Tier 0 to individual scientists' desk/lap/palmtops at Tier 3), CERN is distributing LHC data and computations across resources worldwide to achieve aggregate computational power unprecedented in high-energy physics research. As an example, 'researchers can sit at their laptops, write small programs or macros, submit the programs through the AliEn system, find the necessary ALICE data on AliEn servers, then run their jobs' on upper-tier systems. The full grid comprises small computers, supercomputers, computer clusters, and mass-storage data centers. This system allows 1,000 researchers at 130 organizations in 34 countries to crunch the data, which are disgorged at a rate of 1.25 GB per second from the LHC's detectors."

    I grew up in a Christian home as a Christian of course. But these last three years I kind of took on the title of an Atheist. Being a Bio-Major in college most of what science explains about life all seemed to make more sense then what the bible was telling me. Lately I have been finding myself under some really bad luck. I first got into a fist fight with my mom and then she kicked me out. My car was in her name so she called and canceled my registration. They cut back my hours at work while i was in school and now there is no way for me to get them back. So working 20 hours a week and homeless wasn't a pretty site. My bf let me stay with him and his dad, but while Im there I started noticing pregnancy symptoms. I told him and he want me to get an abortion. I am highly opposed to abortions but he insist that im not gonna mess up his life. Then he starts getting sick. And i mean extremely sick sore throat, body aches, fever, chills, swollen gums and canker sores and pain in his mouth.

    About five days into him getting sick and seeing his condition not getting any better, I started to pray. I felt so bad praying and furthermore i felt like no one was listening. But two days later his condition got better. No more body aches, no more sore throat, or fever... but the swollen gums, and ccanker sores were still there. It was so painful he refused to eat. So i prayed some more but nttn happened. i figured the first time it was just a coincidence and there was still no God.

    Yesterday while we were at work, my boyfriend texted me about the abortion and I told him yes I would get one if Im pregnant.(we still arent sure dr. appt monday). He also texted me and told me while he was at a grocery store with his cousins a weird crazy guy shouted "LIAR" in his face. Which was weird but where im from alot of crazy ppl do crazy things so i didnt really think anything of it. After he told me that I poured my heart out to him about how I been praying for him, my bf a somewhat Atheist too was shocked. He said he would pray with me tonight about his health. At that moment I realized if there was a God us praying is so unfair. We came back to him when everything started going wrong but when things start to go right will we walk away again.

    When i left work it started raining extra heavy. Like as soon as I left out the door and once I got in shelter under the bus station it stopped. Again didnt think anything of it because it was raining on and off for about a hour while i was at work. I caught the bus to my BF apartment and while i was walking home it began to lightening. And anybody who knows me Know that I am afraid of lightening. As a kid you couldn't put me near a window during a thunderstorm. Now that I am older its easier to compose myself but im still scared. So im walking extra fast to get to my BF apartment complex. Then a loud thunder cloud clapped. I asked in my head "God are you mad at me?" and this big lightening bolt came down and struck the electrical pole. Next thing I knew it was pitch black outside. It scared the living daylights out of me and I ran to my BF apartment.

    Of all this stuff happening, do you think its just a coincidence or are these signs? And believe me this is a true story. everything that i said happen really did happen. I am not a christian trying to change the beliefs of Atheists or any one I just want to know if you were in my position and all this happened would you take it as being God or merely a coincidence?
