Raspberry Pi 4Bは1.5GHzで動作していますから1,800MIPS/core以上の処理能力があるはずです。GILがありインタープリターのRaspberry PiのPythonでも17MB/sのTCP送受信ができます。MIPSというのは最近あまり使わないのでマイナーですがアセンブラ言語では意識されます。シリアル通信は29Kbps、57Kbps、115Kbpsの速度です。Windowsはハイパーターミナルが消えましたが、今でもダメな時はまずシリアルです。一方、LANの速度は普通で1Gbpsです。そしてTCP/IP、USB2以上、さらにSDカードではアセンブラのライブラリーは見かけることはありません。特にTCP/IPスタックは膨大です。また出だしから脈絡のない話で何を言っているのか分からなくなりましたが、今回の主題は、複数台を使う分散処理により、整数型で高次方程式を解くプログラムです。
100次、1000次の高次方程式では1台の４core並列処理だけでは長時間かかります。そこで２台で分散処理すれば計算時間は1/2、3台では1/3、4台では1/4になります。プログラムは高次方程式の計算部分本体が律速です。この部分を複数台に分ければ、台数分で計算時間は短縮されます。またこの計算部分本体の計算時間が数時間であることに対して、LAN通信の遅延は数秒です。複数台のLAN通信での分散処理が、計算時間の短縮に大きなメリットがあります。次に今回の分散処理で使った複数台のLAN構成を示します。
* 今回の予定は「整数型で高次方程式を解く＝分散並列処理＝」でしたが、タイトルだけ変更しました。内容は同じです。
#分散処理LANの基本ユニット
５ポートのギガビットスイッチングハブでLANを構成しています。

固定IPアドレスを使い、OSのアップグレード時以外はハブでLANを構成しています。計算用4台と集計用1台です。TCPのsocket通信は、同じRaspberry Pi 4B同士のCoreToCoreです。同じ機種でのCoreToCore通信ですから送受信のタイムミングが大変よく合います。ただ受信側では受信バッファーを別変数（大容量）に追記する重いステップがあるのと比較して、送信側では小さな14400byteを送信バッファーへ書き込むだけの軽いステップですから、受信側に１タイムラグの遅延があるようです。次に作成した分散処理のプログラムを示します。
#分散並列処理のプログラム簡易版

計算用が1台しかないので分散処理とは言えないですが、台数を増やす前の確認のために作成したプログラムです。Raspberry Pi 4B メモリー2GB 1台とPC Windows 10版Python IDLE 1台の混成でも、さらに計算用と集計用を入れ替えても、動きました。試行はしていませんが、Mａｃ版Python IDLEでも動くかもしれません。Pythonプログラムが動けば、あとはノード間のTCP通信ですから、LANケーブルが接続されLEDが点灯していて、IPaddressとportが合っていれば、基本的には通信できるはずです。固定IPアドレスです。
プログラム上、TCP通信はmultiprocessingの１プロセスで送受信します。計算部分は4coreを使う４プロセスです。以下にプログラムを示します。最初が計算用のプログラムtrib-calc1.pyです。その次が集計用のプログラムtrib-total1.pyです。（後日記：Mac OSではプログラム中の14400を8192へ変更した方がいいかもしれません。送受信速度が遅いだけで他に支障はないと思いますが。TCPはOSに依存していますから。）

これも計算用trib-calc2-1.py、trib-calc2-2.pyを先に実行して待機します。後で集計用trib-total2.pyを実行すると計算用２台へパラメーターを送信して計算が開始されます。計算時間は1/２になります。
#さらに多台数での分散処理
計算用を8台さらに16台へと増やすことが可能です。

そうすれば計算時間は1/8、1/16と短縮されていきます。図は１６台構成の分散処理の1例を示しました。セグメントを分けるにはＲＵＴＥＲを使うのが一般的ですが、今回の用途では小セグメントに分けるのにシンプルなＳＷＩＴＣＨを使っても同じ機能をします。16台、数十台、数百台と構成台数が増えても、セグメントに分ければブロードキャストは気になりません。
ただ整数型で計算した場合、生データの桁数は大きくなり、今回のプログラムを実行すればわかりますが1000次方程式でさえ４MBでした。10000次方程式の整数型の生データは100MBを超えそうです。Raspberry Pi 4BのPythonの今回のプログラムでは17MB/sの受信処理が可能ですから、100MBでも6秒ほどで送受信は可能です。4coreでは４台からも受信可能です。さらに台数が8台、16台と増え、計算結果送信が併発すると、さすがに混雑したＬＡＮとなります。ただ計算結果送信の一時期だけです。ゆえに送信前に、一極集中する集計用の受信側の空きを、送信側プログラム上で事前確認するだけで解決できそうです。数時間計算して、わずか数秒の送信待機の待ち時間です。また一極集中する計算結果の受信バッファーとしてファイルサーバーを併設することも一案です。
最後までご覧いただいて、ありがとうございました。
今回はQiitaの主旨に同意して投稿していますので、公開したプログラムはコピー、改変などでのご使用は自由です。著作権に関する問題も発生しません。
ただし、Raspberry Pi 4Bを使う場合にはCPUに特に大きめのヒートシンクが必須です。LAN通信の頻度の少ない今回のプログラムのような場合、LANチップは熱くなりません。しかし計算時間が継続するとCPUの激しい発熱で分かるように相当電力を使っています。電源UCB Cタイプの後ろにある黒い小さなチップも熱くなりますので、ファンでの風流も必要です。
#16core用20次方程式
以下は、後日追加したプログラムです。16coreのPC向けです。集計用のサーバーを想定しています。単体で動くプログラムです。x=1と14に3重解、x=2と13に2重解がある20次方程式です。グラフは次のようになります。
因数分解型の展開に、次のような小さなプログラムを作り、係数を取得しました。

今回は因数分解型から整数の係数で解きましたからきれいにY値が0.0になります。x=2とx=13はYの符号が反転していません。YYは符号が反転しています。そしてYYYはありません。evenの重解でありYYYが無いので2重解です。x=1とx=14はYの符号が反転しています。YYは符号が反転していません。さらにYYYがあり符号が反転しています。Oddの重解でありYYYがありますからさらに5重解かもしれません。しかし20次方程式で既に20個解が求まっていますから3重解です。
実際の高次方程式を解くと、きれいにY値が0.0になることはなかなかありません。ゆえに4次および5次微分、さらにmatplotlibなどのグラフの併用、そして有効数字を増やして少し時間をかけて再計算し、最終的な解を確定しています。
