Unformatted text preview: 8. Define the term ”Benchmark”, and describe how it is used to evaluate a computer system. (10 points). A benchmark is like a baseline performance for a certain task that uses certain resources. It is used to compare the performance of that task on different supercomputers. It is used to evaluate a computer s stem to see what each benchmark applications baseline time is. You then can start tweaking the architecture to try and improve that benchmark. here are specific benchmarks that stress test different parts such as network, storage, computational power, etc. 9. Suppose that you are designing a high performance computing system from commodity components, and have the following available for your use: i} a prototype of two computational nodes, which are candidates for use in your system; ii} the application that will be using the system you are designing; and iii) a suite of microbenchmarks and application level benchmarks. Describe the process you would follow to determine which of the two prototype nodes you will use for the system. (10 points). If time was not a factor for building the best system for the application this is the approach I would use. I would identify the needs of the application, like if it was la’O intensive, network intensive, etc. I would then build two smaller scale s stems and identify the differences in each one. Once each smaller scale system is built of the two prototype candidates I would then start benchmarking each one. I would focus ont benchmarks that are the needs of the application that I will be running on. I would record the best results for the related benchmarks that fit the needs of the application I will be running and do a compan'sion chart to figure out which computational node prototype would fit best for the application needs. ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
