NumNodes コマンドは、並列計算において実行される Maple コードから利用できます。

並列ジョブが N 個のノード上で起動されたとします。この計算中、各ノードは 0 から N-1 までの整数の識別番号を割り当てられます。NumNodes() は、この並列計算に参加している全ノードの数 N を戻します。

この関数は Grid パッケージに含まれているので、コマンド with(Grid) を実行してからのみ 短縮形 Grid(..) で呼び出せます。原形 のコマンド Grid[NumNodes](..) を使えばいつでも利用できます。

Grid[NumNodes] コマンドは Maple 15 より導入されました。

Maple 15 の変更点についての詳細は、Maple 15 の更新情報 をご覧ください。
