This repository contains a Go implementation of Lemire's "Fast Random Integer Generation in an Interval". See also Lemire's blog post and this blog post for more details.
The algorithm is Uint32n() in random.go, with tests and benchmarks in random_test.go.
The tests use the testify testing library, so first install it:
go get -u github.com/stretchr/testify
Then to run the tests, make sure that this repository is in $GOPATH/github.com/akalin/random, and do
go test -v github.com/akalin/random
and to run the benchmarks, do
go test -v github.com/akalin/random -bench .
