gratest questions and answers

IIM-A interview This is a fact and not a story....This happened during the interview rounds of IIM (A) for the class of 2004........Interviewer said "I shall either ask you ten easy questions or onereally difficult question. Think well before you make up your mind!"The boy thought for a while and said, "my choice is one really difficult question.""Well, good luck to you, you have made your own choice! Now tell me this. What comes first, Day or Night?"The boy was jolted into reality as his admission depends on thecorrectness of his answer, but he thought for a while and said,"It's the DAY sir!""How" the interviewer asked."Sorry sir, you promised me that you will not ask me a SECOND difficult question!" He was selected for IIM!"Technical Skill is the mastery of complexity, while Creativity is the master of simplicity...See the questions & answers below: The answers were given by people who have exceptionaly high IQ.

Multicore

Multicore processors - Tomorrow today?Computer performance has been driven largely by decreasing the size of the chips while increasing the number of transistors they contain. In accordance with Moore’s law,this has caused chip speeds to rise and prices to drop. This ongoing trend has driven much of the computing industry for years. However transistors can’t shrink forever.Even now, as transistor components grow thinner, chip manufacturers have struggled to cope with Power Usage & Heat Generation, two critical problems.In response, manufacturers are building chips with multiple cooler running, more energy-efficient processing cores instead of one increasingly powerful core. The multicore chips don’t necessarily run as fast as the high performance single-core models, but they improve overall performance by handling more work in parallel."Multicores are a way to extend Moore’s law so that the user gets more performance out of a piece of a silicon," said John Williams, AMD’s technical director for server microprocessor planning. Chip makers AMD, IBM, Intel and Sun are now introducing multicore chips for servers, desktops and laptops. The dual core processors Pentium-D dual core Pentium 4 by INTEL and Opteron 875 dual core By AMD are launched. At the end of 2007, a quad core "Whitefield CPU" will be launched by Intel, and a quad core "K9" of AMD will make a stand against Whitefield. The multi core train has picked up speed and is unstoppable. The conclusion of many industry analysts and researchers is that the single-core CPU has no future. A quote from Shekhar Borkar, Intel Fellow, Director: "Multiprocessing, on the other hand, has potential to provide near linear performance improvement. Two smaller processors, instead of a large monolithic processor, can potentially provide 70-80% more performance, compare this to only 40% from the large monolithic processor." Note the word "monolithic", a word with a rather pejorative meaning, which insinuates that the current single core CPUs are based on old technology. So, basically the single core CPU has no future as it improves performance only by 40%, while doubling complexity .This reasoning explains why all of sudden Intel marketing does not talk anymore about 10 GHz CPUs, but about the "era of thread parallelism".A multi-core microprocessor is one which combines two or more independent processors into a single package, often a single integrated circuit (IC). A dual-core device contains only two independent microprocessors. In general, multi-core microprocessors allow a computing device to exhibit some form of thread-level parallelism (TLP) without including multiple microprocessors in separate physical packages. The concept of a thread rather thread of execution is split a program into 2 or more simultaneous running tasks. The term Thread Level Parallelism is the parallelism inherent in an application that runs multiple threads at once. This form of TLP is often known as chip-level multiprocessing, or CMP.In a dualcore CPU system we can run a single-threaded application on CPU1, and turn the CPU2 off. When CPU1 gets almost hot, one let CPU2 continue to do the work. As a result, we can reduce the average temperature of one CPU core. As leakage decreases with lower die temperatures, this technique can reduce overall leakage power. The objective of using a dualcore CPU is then primarily to reduce power consumption in situations where there is only one CPU intensive application. This is probably the reason why Intel sees a great future for dual core CPUs in the mobile market, although the mobile market is probably the last market where we will be able to benefit from dual core power. The last thing that we want is twice as much power dissipation because the two cores get active. In our humble opinion, dual core will be only dual when it is not working on battery power.Physically, the multi-core CPU designs require much less Printed Circuit Board (PCB) space than multi-chip SMP(symmetric multiprocessor) designs.One of the another major advantage of multi-core processors are True Multasking.Since in the single-core processor when we run multiple program such as cd burning, music playing, and playing games means processor has to share between all those programs, but in the multi-core system one processor core can handle the Cd burning and other core can play music.Software benefits from multicore architectures where code can be executed in parallel, under most common operating systems this requires code to execute in separate threads. Each application running on a system runs in its own thread so multiple applications will benefit from multicore architectures. Each application may also have multiple threads but must be specifically written to do so. Operating system software also tends to run many threads as a part of its normal operation.But there are some another issues also. Most application software are not written to use multiple threads because of the challenge in doing so. Programming threaded code sometimes requires complex co-ordination of threads and can easily introduce subtle and difficult to find bugs due to the interleaving of processes on data shared between threads. Also there has been perceived lack of motivation for writing threaded applications because of the relative rareness of multiprocessor hardware, although threaded applications tend to perform better even on single processor machines. In addition to operating system (OS) to support, adjustments to existing software are required to maximize utilization of the computing resources provided by multi-core processors.Also, the ability of multi-core processors to increase application performance depends on the use of multiple threads within applications. For example, most current video games will run faster on a 3 GHz single-core processor than on a 2GHz dual-core, despite the dual-core theoretically having more processing power, because they are incapable of efficiently using more than one core at a time.In the future, manufacturers will make their multicore chips faster by increasing the speed of each core,as Sun is already done.In 1999 Sun released the Microprocessor Architecture for Java Computing dual-core,multimedia,desktop chip.Now Sun’s Trembly said, The company is working on Niagara multicore chip for high-end servers.Planned for release early next year, Niagara will have eight cores,each handling four threads.Multicore processors will find a natural home in Servers,said Williams,AMD’s fellow,but won’t be very useful in desktop’s until vendors develop considerably more multithreaded PCs for a while.’The pre-processor fees that enterprise software vendors charge their customers could be a challenge to multicore chip’s success", said Williams and also added "Multiple cores are the new gigahertz. Multicore will be the transition from brute-force performance to architectural elegance". So we have already entered a new era of processing that will revolutionize the processing paradigm in next years.
