Laboratory work №1. Calculating the performance metrics of a computer system:

system: speed, efficiency, energy costs, Amdahl's law, cpu time

speed, efficiency, energy costs, Amdahl's law, CPU time and conduct

RAM performance testing to build a PC structural diagram.

about the hardware and software configuration of the computer. The

program analyzes the computer configuration and provides detailed information about the devices installed in the system - processors, motherboards, video cards, audio cards, memory modules and etc, as well as information about their characteristics, supported sets of commands and operating modes, their manufacturers, installed software , operating system configuration and installed drivers.
The program has a wide range of tests:
1) reading from memory - tests the speed of data transfer from RAM to the processor;
2) recording in memory;
3) copy-in-memory - tests the speed of transferring data from one memory location to another via the processor's cache;
4) memory latency - tests the average time the processor reads data from RAM;

Write out from the list of the main parameters of

the computer under examination in the right window:
type of computer;
type of operating system;
user name;
type of CPU;
type of motherboard;
the type of chipset of the motherboard;
number and type of RAM;
type of video adapter;
type of monitor;
type and amount of disk storage;
List other In / Out devices on the PC under test.

under investigation.Write down the main CPU parameters from the list

in the right window:
type of CPU;
core name of the CPU;
CPU stepping;
instruction sets;
initial frequency;
the size and characteristics of the CPU's cache;
