The flaw was first discovered in June 1994, when Intel engineers first noticed that the floating-point unit (FPU) on the chip gave the wrong answer. However future tests done by Intel showed that the error appeared only in the ninth significant digit of the answer and affected a very, very small percentage of possible division combinations. The results of this flaw…
The “Pentium flaw” or the Pentium FDIV bug was when Intel released defective Pentium processors. The defect was malfunctioning P5 Pentium floating point unit causing the computer to calculate division incorrectly. The “bug” was discovered by Professor Thomas Nicely when working on mathematical equations and noticed many inconsistencies in his calculations when he added a Pentium based computer on June, 13, 1994. Intel tried to keep the bug out of the lime light while they worked on updates to try and fix the problem but, persistent consumers kept pushing the issue on the internet and in magazines.…

Back in June, 1994 the Pentium Flaw was noticed by Intel testers, who had discovered a division error on the Pentium chip. Intel managers didn’t see this as a major problem so they kept this from anyone outside their corporation. The nature of this issue was a mathematical problem in their Floating Point Unit (FPU), or the math coprocessor. The Pentium chip was having glitches in calculating large divisions. It wasn’t until October 19th, when Dr. Thomas R. Nicely had revealed the malfunction of the (FPU) trying to do certain calculations. Dr. Nicely was a mathematics teacher at Lynchburg College in Virginia. After running several test on the 486 and Pentium he had pin pointed the error to the Pentium chip. Dr. Nicely contacted Intel and they had confirmed the error, but said they had no reports till then. Intel handled the situation very poorly; they would not return contact to Dr. Nicely, forcing him to write a…
In June 1994, Intel discovered the floating-point unit flaw in the Pentium microprocessor. Professor Thomas Nicely, a professor of mathematics at the Lynchburg College, had written code to enumerate primes, twin primes, prime triplets, and prime quadruplets. Professor Thomas Nicely noticed some inconsistencies in the calculations on June 13th , 1994 shortly after adding a Pentium system to his group of computers, but was unable to eliminate other possible factors (such as programming errors, motherboard chipsets, etc.) until October 19, 1994. On October 24th, 1994 he reported the flaw he encountered to Intel. According to Professor Thomas Nicely, the person that he contacted at Intel later admitted to Intel being aware of the flaw since May 1994. The flaw was discovered by Intel during testing of the FPU for its new P6 core, which was first used in the Pentium Pro.…
With reality shows taking over airtime nowadays, psychological thrillers in television are a rare genre. Admittedly, it can be a tasking genre to develop a show around, but Vince Gilligan has managed to create, quite possibly one of the greatest shows ever, Breaking Bad. In the pilot episode, the audience was introduced to Walter White, a middle-aged high school Chemistry teacher. He sounds like an average, typical man, but he was introduced in the most peculiar way. Gilligan opened this award-winning show with Walter, underwear-clad, holding a pistol, next to a crashed R.V. in the middle of the desert. The audience questioned this of course. How is this man in such a bizarre situation? What’s even going on? Although the opening was abnormal and confusing at first, Gilligan effectively developed Walter’s character throughout the series, as well as his alter ego known as Heisenberg, using an engrossing story, excellent character development, and the appeal of pathos.…

Immediate Issue: As Andrew Grove, during my meeting of December 17,1994 with my internal team, Should I approve replacing the defective Intel chips of all concerned users with no-question asked? Also, should we also pay for the labor and other incidental costs? How should we integrate our decision into our financial books?…

The Pentium Flaw a divisional error was discovered in the summer of 1994. The flaw was discovered by Intel. Intel decided that their chips did not need to be recalled since the chance of the average user discovering the error was less than 1 in 9 billion. Thomas Nicely a mathematics professor at Lynchburg College in Lynchburg VA made error public when he sent an e-mail to several colleagues. Nicely was using several computers to compute mathematical problems to prove they had enough power to do so.…
June 1994: Intel testers discover a division error in the Pentium chip. Intel managers decide that the error will not affect many people and do not inform anyone outside the company. This was Intel's first mistake. The company was right in that the division error could affect only a few customers, but not disclosing the information made Intel appear to hide a sinister secret. It sent the message to customers that Intel was not trustworthy. Disclosing the flaw upon discovery would have created only minor news, on the same low level as an automaker announcing a minor defect. The same month, Dr. Thomas R. Nicely, a professor…
The Pentium FDIV bug was a bug in the Intel P5 Pentium floating point unit (FPU). Because of the bug, the processor would return incorrect results for many calculations used in math and science. Intel blamed the problem on a few missing entries in the lookup table used by the company. The error was discovered by Professor Thomas R. Nicely at Lynchburg College, Virginia, USA. The error was rarely encountered by users (Byte magazine estimated that 1 in 9 billion floating point divides with random parameters would produce inaccurate results).[3] However, both the flaw and Intel's initial handling of the matter were heavily criticized. Intel ultimately recalled the defective processors.…

This paper explains the architecture development and challenges of multi-core processing, plus provides a glimpse into the upcoming Intel quad-core processors and the direction in which Intel is taking multi-core processors to the future. We discuss many of the benefits you will see as we continue to increase processor performance, energy efficiency, and capabilities. Multi-core processor capability is central to the Intel platform-centric approach. By enabling enhanced performance, reduced power consumption and more efficient simultaneous processing of multiple tasks, multi-core processors promise to improve the user experience in home and business environments.…
