最近、EC2の新しいインスタンスタイプが出るたびにUnixBenchのスコアを見てニヤニヤすることが趣味になってきています。でも一々インスタンスを起動して、UnixBenchをインストールしてベンチマークするのが面倒になってきたのでCloudFormationで一発取得できるようにしてみました。
概要
以下のように動作します。
- CloudFormationテンプレートからStackを起動して、SpotインスタンスのAuto Scaling構成のEC2を起動します
- UnixBenchをインストールして、ベンチマークを実行します。
- UnixBenchの実行結果をS3へアップロードします。
- ベンチマーク後にCloudFormationのStackを削除します。
ポイントは、Auto Scalingにしてサンプル数を増やせること、Spotインスタンスを使用してコストを抑えることです。
テンプレート
CloudFormationのテンプレートは、以下のようになっています。 UnixBenchは16コア以上に対応していないため、テンプレート内でパッチを適用しています。

}ベンチマーク内容
ベンチマークは、以下の内容で実施しています。
- AMI：Amazon Linux AMI 2015.03.0 x86_64 HVM GP2
- インスタンスタイプ：可変（HVM対応のみ）
- ディスク：gp2が1ボリューム（サイズはパラメータで可変）
- UnixBench：UnixBench 5.1.3（パッチ適用版）
インスタンスタイプのHVM対応の可否はAmazon EC2再入門 2015年7月版をご確認下さい。
実行する
Select Template
このテンプレートを起動すると以下のようになります。
Specify Parameters
このStackのパラメータは以下のようになっています。
| パラメータ | 内容 |
|---|---|
| AllocatedStorage | ルートボリュームのサイズです。ストレージタイプはgp2です。デフォルトは"1,000GB"です。 |
| InstanceCount | ベンチマークを実施するインスタンス数です。デフォルトは"1"で、最大値は"10"です。 |
| InstanceType | ベンチマーク対象のインスタンスタイプです。デフォルトは"c3.large"です。なお使用するAMIはHVMなのでHVM対応インスタンス以外は正常に起動しません。 |
| KeyName | EC2に適用するKey Pairです。 |
| SpotPrice | 適用するSpot価格です。デフォルトは"$1"です。 |
| TargetS3Bucket | 結果をアップロードするS3バケットです。実行するアカウントのバケット名を入力してください。 |
| TargetS3Prefix | 結果をアップロードする場所を指定します。デフォルトは"benchmarking/"です。 |
| TargetSubnets | EC2を起動するサブネットを選択します。 |
| VPC | EC2を起動するVPCを選択します。 |
Options
Optionsはそのままで進めます。
Review
Reviewでは、一番下のI acknowledge that this template might cause AWS CloudFormation to create IAM resources.にチェックを入れます。
Stackが起動しました。ベンチマークが終了するまで1時間ほど待ちます。なお、実行後にベンチマークのStackは自動で消えるので安心してください。
ベンチマーク結果
S3の対象パスに実行結果のファイルが出力されます。

さいごに
これで簡単にベンチマークができるようになりました。しかしUnixBenchは古いベンチマークツールなのでCPUのコアが多数の場合は効率的に動作せずにスコアが伸びないようです。また細かな計測環境の違いによってもベンチマークのコスアが大きく変動することもあります。あくまでも参考情報であることを認識してベンチマークを行いましょう。
