module gt4_history のアプリケーション. 変数毎に時・空間に自由にサンプリングを設定できる. 長くなりそうな出力の時分割や並列化に対応. その他の特徴 * 一つの変数を切り方や時間間隔を変えて複数出すこともできる。 * 並列化対応は、単にプロセス固有のサフィックスをファイル名に付けられる だけという単純なものである。MPIなどを使う際に、各ノードが自分の 受け持ちの領域をそれぞれ独立なファイルに出すことを想定している。 * 時間積分ループ内でデータを出力するためのコーディングを楽にする工夫 * 出力する変数に関する諸々の情報はモジュール内部に取っておき、 外部からは名前で指定する。生の gt4f90io の場合、出力初期化でできた GT_HISTORY 構造体を実際の出力場所に渡さなければない。そうすると 時間積分のループの内と外をどうやって繋ぐかという悩みが発生するが、 ここではその悩みから解放される。 * 出力するタイミングも内部で管理されるため時間積分ループ内で毎回出力 命令を呼んで構わない。なお、出力のためだけに特別に計算する物理量を 無駄に計算しないための工夫もある(関数((<HistoryAutoWhetherPutNow>))) * 地図投影座標のように、多次元の座標(補助)変数を出力したい場合も考慮さ れている(((<HistoryAutoCreate>))のオプション引数 ancilcrdvars)。 * 任意の属性が簡単に追加できる(((<HistoryAutoCreate>))のオプション引数 attrs)。

* 長さ (*) の配列は本当に必要か? 実は (:) にしたいんだけど、 長さチェック実装を面倒がって当座 (*) にしたんでは?? もしそれだけの問題なら、長さチェックをするようにして、まずければ 例外が発生するようにすべき。 * 現在は内部データの保持は単なる linked list を使っているが、 登録変数が多くても高速に検索できるようにするため、2分探索出来る ように変えるべき。 * gt4f90io に上位モジュールとして取り込んで貰う * gt4f90io に整合的なドキュメンテーション (あるいは dcpam的に?)
—subroutine HistoryAutoCreate( name, aryshape, &
& longname, units, slfst, sllst, slstp, & & file, title, source, institution, & & dims, axlongnames, axunits, axxtypes, & & time_to_start, put_interval, dt, & & conventions, gt_version, & & proc, newfile_interval, spcoordvars, & & ancilcrdvars, attrs ) ヒストリファイル初期化情報の設定。実際のファイル初期化は 必要に応じて HistoryAutoPut が行う(時分割するときは適宜 クローズと初期化を繰り返さないとならないので、そういう 構造になる)。なお、一つのファイルへの出力に対して このサブルーチンを2回以上呼んではならない。複数の 変数を一つのファイルに出したい場合は、HistoryAutoCopyCreate を利用せよ。 時・空間に自由にサンプリングを設定できる。 但し、いずれも等間隔。長い時間積分によって、ファイルが 大きくなり過ぎることに対応するため、一定の時間間隔で 分割することが可能。また、並列化を念頭に各ノードを特定する 文字列を挿入することができる。
—subroutine HistoryAutoCopyCreate( name, longname, units [, file] )
直前の HistoryAutoCreate を使って、格子及び出力の空間・時間 サンプリングが同じ出力を定義する。fileを省略すれば 同じファイルを使う。
—subroutine HistoryAutoPut(name, vals, time)
変数の出力を行う。タイミングは内部で制御するので、全タイム ステップで呼べば良い。なお、下記の HistoryAutoWhetherPutNow を使って呼ぶタイミングを制御しても良い。
—logical function HistoryAutoWhetherPutNow( name, time )
name の名を持つ出力項目に関し、現在がファイルに出力するタイミ ングかどうかを返す。同名で複数の出力をする場合、どれか一つでも 出力するタイミングなら .true. を返す。出力のために特別に計算を を要するようなケースに使うと良い。(ほとんどのステップで無駄に なる計算をするのを避けられる)
—GT4_ATTRIBUTE
属性を名前と値の組で入れる
—GT4_ATTRIBUTE function init_gt4_attribute(name,rval,ival,cval)
ATTRIBUTEのコンストラクター. 名前 & (実数配列 or 整数配列 or 文字列) を与える
—GT4_REAL1D
配列の配列をつくるための型(実数)
—GT4_REAL1D function init_gt4_real1d(ary)
REAL1Dのコンストラクター.
—GT4_NAMED_REALARY
名前、次元名、longname, units を持つ実数配列. 配列データは1次元で保持
—GT4_NAMED_REALARY function init_gt4_named_realary(name,rank,dims,length,ary,longname,units)
GT4_NAMED_REALARYのコンストラクター.
