computer-benchmark

Some tools for benchmarking computer performance.

This repository contains a set of Go programs used to stress different components of a computer. Each benchmark focuses on a specific workload such as matrix multiplication, memory bandwidth (STREAM), FFT, sorting and cryptography. There are both single-threaded and multithreaded variants.

Run the benchmarks using go run . and choose which test to execute from the interactive menu.

Building the benchmarks

To compile the benchmark binary run:

go build -o benchmark

The above command produces an executable called benchmark in the current directory.

Running the benchmarks

After building, execute the benchmarks with:

./benchmark

Alternatively the code can be run directly without building using:

go run ./...

Executing unit tests

If unit tests are present they can be run with:

go test ./...

This command recursively executes all tests in the repository.

Configurable parameters

Benchmark sizes are controlled via constants within the source code. For example:

• matrixMultiplicationSize in multithreaded/matrix_multiplication.go
• streamArraySize in multithreaded/stream.go
• dataSize in multithreaded/crypto.go

Modifying these constants allows changing the amount of work performed by each benchmark. There are currently no environment variables for configuration.
