Compute fast of computer
- 2. What is fast of computer? • If your computer is too old, you would wait for browsing a website. • If your computer has a lot of memories, you don’t have to wait for browsing. • your computer is checked by tesOng benchmarking.
- 4. Materials(1) • A computer which with web browser and Internet access • Calculator or spreadsheet program(e.g. Excel), doe analyzing data • Lab notebook • Graph paper
- 5. Materials(2) • OpOonal: • Python 3 with IDLE and Python 3 Oming test code • C compiler and C language Oming test code
- 6. What is the test code?(1) • It is a program which measure the run Ome. • It repeat the same calculate and when it finish, the program return the Ome it took. • CalculaOon can be selected among sum, subtract, mulOply and divide.
- 7. What is the test code?(2) • The Ome is subtracted start Ome from end Ome. • You can measure the Ome by other language. • Test code is called background research.
- 9. Procedure(2) • Next, you create a data table in lab notebook or spreadsheet program. • The data table has • whose (or what) computer • selected data type (e.g. int 8bit, 16bit..) • selected mathemaOcal operaOon • number of trials (IteraOons) • result of Ome(ms) • number of calculaOons per Ome(operaOons/ms)
- 10. Procedure(3) • Third, you do running the test code and record the result of time. • Then, you have to record the all selection. • You do many cases and record them.
- 11. Procedure(4) • Finally, you analyze your data. • You use a calculator or spreadsheet program to calculate the average processing time for each combination.
- 12. Procedure(5) • You make four bar graphs to examine if the amount of the time that the computer needed to do a single type of mathematical operation(like addition). • Mathematical operation changes with different data types.
- 13. Procedure(7)-a • You make one bar graph for each type of mathematical operation. • There will be a total of four graphs which has addition, subtraction, multiplication, and division.
- 14. Procedure(7)-b • You make one bar graph for each type of mathematical operation. • There will be a total of four graphs which has addition, subtraction, multiplication, and division. • Each graph should have one for each data type. • The height of each bar should be equal the average time for that combination.
- 15. Procedure(8) • Last, you look at all four bar graphs. • You can find that what computer is slower or faster than other. • You compete your predictions and graphs of result.
