# Introduction

Builders that are managed by the coordinator (VMs running on GCE or reverse buildlets, such as the new OS X builders) are listed here:

http://farmer.golang.org/builders

For design details about the coordinator, see http://golang.org/s/builderplan

Older-style builders are listed below. These builders are configured and run manually. The goal is to migrate as many as possible over to the new system.

# Builder Requirements
  * internet connection (at least be able to access Google and http://build.golang.org)
  * preferably with two or more (V)CPUs, as at least one test (` sync/atomic ` requires ` runtime.NumCPU() > 1 ` to test more completely)
  * at least 512MiB of memory

# Restrictions
  * The combination of Ubuntu 11.10 or 12.04 OMAP4 kernel and pandaboard (ES) have proven unstable as builders. See [issue 4305](https://code.google.com/p/go/issues/detail?id=4305). Make sure you have updated to the latest available 12.04.2 release.

# How to set up a builder
  1. obtain a hash from Go team members, and put that in ` ~/.gobuildkey `
  1. go get golang.org/x/build/cmd/builder
  1. builder YOUR\_BUILDER\_NAME

# Special notes
  * Please make sure you've installed root certificates and that it's accessible to Go programs. For example, on NetBSD, you will need to install ` security/mozilla-rootcerts `.
  * If your builder runs Unix, please install ` perl `, as tests for ` go.tools/cmd/vet ` need it.
  * Use ` screen(1) ` instead of ` tmux(1) ` to host the ` builder ` process, as the later interferes with some of the ` os/signal ` tests.
  * Raise ` ulimit `s on Unix: thread count (` -r `), nofiles (` -n `, 1024 should be fine)
