３ LAM Rmpiが入ったところで動作確認

lamをとめて、ブートして、Ｒを立ち上げて、Rmpiパッケージを読み込んで、Rmpiの関数をいくつか使って、それぞれを閉じて、Ｒも閉じて、lamも止めている。途中Rmpiパッケージを読み込んだところで、エラー "rsprng package is not installed. Cannot use SPRNG." が出ている。rsprngパッケージとは『rsprng
SPRNG (Scalable Parallel Random Number Generators) APIs とのインターフェイス, およびその使用のための実行例と文書を提供します. 』--(RWikiの記事より)
並列処理に合致させた乱数発生は必要なので、このパッケージもインストールが必要。そのインストールはこちら

koiti_yano氏のブログでは、ここが >simple.pi(1000)となっていて、エラーが出ていない
おそらくsprngが動いているからと思われる(未確認)
