DOriginalRoadrunnerOn the current TOP 500 list of worldwide supercomputers released in June 2008, Roadrunner, IBM's new super computer, is rated No.1, exceeding IBM Blue Gene, the former No.1 on the list. IBM calls Roadrunner the world’s first “hybrid” supercomputer. It combines 12,960 IBM Cell chips, which power Sony's PlayStation 3 video game machine, with 6,948 dual-core AMD Opteron chips and 80 terabytes of memory. It runs Red Hat Linux.Roadrunner is billed at the fastest in the world, operating at one petaflop or one thousand trillion calculations per second. So, exactly how fast is the supercomputer? IBM said the speed is roughly equivalent to the combined computing power of 100,000 of today's fastest laptop computers - users would need a stack of laptops 1.5 miles high to match Roadrunner's performance. It would also take the entire population of the earth - about 6 billion people - each working a handheld calculator at the rate of 1 second per calculation more than 46 years to do what Roadrunner can doin one day.IBM said that in the past 10 years, supercomputer power has increased about 1,000 times. Today, just three of Roadrunner's 3,456 tri-blade units have the same power as the 1998 fastest computer. Now, a complex physics calculation that will take Roadrunner one week to complete would have taken the 1998 machine 20 years to finish.Dictation1. twentieth century2. citizen3. mathematical4. early development5. career6. stored7. memory8. operate9. electronic 10. calculation 11. memories 12. manner 13. control unit 14. calculating unit 15. control unit 16. a piece of data 17. accordingly 18. advancement 19. architecture 20. majorityUnit 2Part1 Reading and TranslatingSection AⅠ. 1.

DOriginalIntelThe Intel Corporation is the leading maker of semiconductor chips, and its products are found in a vast majority of personal computers. Headquartered in Santa Clara, Calif., Intel was founded in 1968 as Int egrated El ectronics Corporation by two giants of the early semiconductor industry, Gordon E. Moore and Robert N. Noyce. Mr. Moore is widely known for the principle called Moore’s Law, which asserts that the number of transistors on a chip, and therefore the chip's performance, doubles roughly every two years. Mr. Noyce is a co-inventor of the integrated circuit. Intel’s third employee was Andrew S. Gro ve, who led Intel through its transformation into the premier manufacturer of microprocessors and is now remembered as the company’s key business and strategic leader.While Intel created the first commercial microprocessor chip in 1971, it was not until the successof the personal computer that this became their primary business. Originally known primarily to engineers and technologists, Intel’s successful “Intel Inside” advertising campaign of the 1990s made it and its Pentium processor household names. During this period Intel embarked on an unprecedented growth and became the dominant supplier of microprocessors for PCs.But in the early 2000s Intel stumbled badly, having hit a developmental wall, and its main rival,A.M.D. was able to engage Intel in a bruising price war. To maintain its leadership position, Intel has been refocusing on its multi-core processing strategy. The process, which is the addition of multiple computing cores onto a single piece of silicon, speeds the chip’s processing ability while limiting its heat generation.Dictation1. mistakenly2. stole3. in truth4. interaction5. tool6. contributed7. teleconferencing8. shell9. wheels 10. application 11. nicknamed 12. tail 13. ahead 14. commercially 15. proves16. concept 17. human intellect 18. dealing with 19. acknowledgement 20. collaborationUnit 3Part1 Reading and TranslatingSection AⅠ. 1.
