go-benchmarks

Test the performance of CPU using a CLI tool built in Go.

Usage

Check the usage of benchmarks.exe:

> ./benchmarks.exe --help
Usage of ./benchmarks.exe:
  -t duration
        Duration for each test phase (default 3s)

Examples

Run benchmarks.exe on Windows:

> ./benchmarks.exe

 Go CPU Float64 Benchmark Tool (v0.2.0)
-----------------------------------------------------------------
 Arch         : amd64 / windows
 Logical CPUs : 20
 Precision    : Float64 (Double Precision)
 Mode         : FMA Simulation (ILP Optimized)
=================================================================

[1/2] Running Single-Core Benchmark... Done.
[2/2] Running Multi-Core Benchmark (20 Threads)... Done.

 BENCHMARK RESULTS
=================================================================
 Single-Core Performance :     193.19 GFLOPS
 Multi-Core Performance  :    1266.15 GFLOPS
-----------------------------------------------------------------
 Multi-Core Scaling      :       6.55x
=================================================================
 Note: Results represent pure FP64 throughput in Go environment.
 Values are approx. 60-80% of theoretical hardware limits due
 to compiler auto-vectorization constraints.
