CompOrg-Benchmark-Project

Computer Benchmark Suite (C++)

A benchmark testing suite written entirely in C++ for a Computer Organization II course.
The program measures execution times for CPU arithmetic operations, memory access, and hard drive I/O performance.

Overview

This project implements five performance benchmarks:

1. 32-bit Integer Operations Benchmark
2. 64-bit Floating-Point Operations Benchmark
3. Memory Benchmark
4. Hard Drive Benchmark (100-byte transfers)
5. Hard Drive Benchmark (10,000-byte transfers)

Each benchmark records total execution time and outputs the final results at the end of program execution.

Benchmarks

1. 32-bit Integer Operations Benchmark

Operations performed:

• (10^{10}) integer additions
• (5 \times 10^{9}) integer multiplications
• (2 \times 10^{9}) integer divisions

Reference execution time: 100 seconds

---

2. 64-bit Floating-Point Operations Benchmark

Same benchmark structure as the integer test, but using double-precision floating-point values.

Operations performed:

• (10^{10}) floating-point additions
• (5 \times 10^{9}) floating-point multiplications
• (2 \times 10^{9}) floating-point divisions

Reference execution time: 100 seconds

---

3. Memory Benchmark

Operations performed:

• Read from (5 \times 10^{9}) different array elements
• Write to (5 \times 10^{9}) different array elements
• 4 bytes accessed per operation

Reference execution time: 100 seconds

---

4. Hard Drive Benchmark 1

Operations performed:

• Read a file of (10^{9}) bytes
• Write (10^{9}) bytes to a file
• 100-byte transfers per operation

Reference execution time: 250 seconds

---

5. Hard Drive Benchmark 2

Operations performed:

• Read a file of (10^{9}) bytes
• Write (10^{9}) bytes to a file
• 10,000-byte transfers per operation

Reference execution time: 10 seconds

Technologies Used

• C++
• Standard Template Library (STL)
• File Streams (fstream)
• High-resolution timing utilities (chrono)

Compilation

Compile using g++:

g++ benchmark_proj.cc -O1 -o benchmark

Run the program:

./benchmark_compiled

---

Output

The program outputs:

• Integer benchmark execution time
• Floating-point benchmark execution time
• Memory benchmark execution time
• Hard drive benchmark 1 execution time
• Hard drive benchmark 2 execution time

Output is displayed once after all benchmarks complete.
