Sabayon Linux と分散コンピューティング（ Folding@home / Rosetta@home ）で COVID-19（新型コロナウイルス感染症）に対抗する

Last updated at 2020-04-01Posted at 2020-03-26

イタリアがひどいことになり、Sabayon が今どうなってるのか気になっていましたが、フォーラムに新型コロナウイルスに対抗する話が出ていました。

※ Sabayon Linux はイタリア発祥の Gentoo 系ディストリビューションです。

間違い晒し

記事の一部に誤った手順を記載していました。ごめんなさい。

以下、間違った手順を紹介してしまった画像。

※ ~~こんな感じで良いはず。~~ ← ダメ。~~指定すべきはプロジェクトナンバーであってチームナンバーではありません。~~ ← 残念。FAQ によると、プロジェクトナンバーを直接指定することは出来ないそうです。“I support research fighting” で COVID-19 を指定できれば簡単なのですが。

※ 訂正文でも間違ってしまい申し訳ない。

2020/3/28タイトルを一部修正

不正確な表記・記述をしていました。ごめんなさい。

修正前
COVID-19（新型コロナウイルス）

修正後
COVID-19（新型コロナウイルス感染症）

COVID-19:

Coronavirus disease 2019
新型コロナウイルス感染症
2019新型コロナウイルスによる急性呼吸器疾患

SARS-CoV-2:

新型コロナウイルス
SARSコロナウイルス-2
Severe acute respiratory syndrome coronavirus 2（直訳すると『重症急性呼吸器症候群コロナウイルス2』）

Folding@home

https://foldingathome.org/
https://ja.wikipedia.org/wiki/Folding@home

Folding@home（FAH、フォールディング・アット・ホーム[3]）は、2000年10月から北アメリカのスタンフォード大学を中心に行われている分散コンピューティングプロジェクトおよび、それに使用されているコンピュータプログラム。

たんぱく質の折りたたみ構造を解析することで、これに関係する様々な疾病（アルツハイマー病、がん、パーキンソン病、狂牛病など）の治療に役立てるのが目的。このプログラムをダウンロードし、パーソナルコンピュータなどで動作させると研究に必要な計算が行われ、その計算結果がインターネットを通じてスタンフォード大学に送られる。また、このプロジェクトではCPUだけでなく、GPGPUによる処理も行う事が出来る。

Folding@home の COVID-19 関連 FAQ

How do I choose to help with the COVID-19 related projects ?
To help in the fight against COVID-19, you need to select
- Webcontrol : "Any disease" in the list "I support research fighting"
- Advanced Control/FAHControl : Configure > Advanced, select "Any" in the list "Cause Preference"
The COVID-19 related projects are on top priority and will be assigned automatically.

Can I choose to work only on the COVID-19 related projects ?
No, you can't.
In FoldingHome, you never choose to work on only one project (or family of projects). The setting described above is a preference, but if no work is available to match your preferences, the system is designed to send you what need to be done at the time of your work request.

以下、上記のGoogle翻訳

COVID-19関連プロジェクトの支援をどのように選択すればよいですか？
COVID-19との戦いを支援するには
-Webcontrol：「I support research fighting」リストで「Any disease」を選択
-Advanced Control / FAHControl：Configure > Advanced、「Cause Preference」リストで「Any」を選択
COVID-19関連プロジェクトは最優先事項であり、自動的に割り当てられます。

COVID-19関連のプロジェクトでのみ作業することを選択できますか？
いいえ、できません。
FoldingHomeでは、1つのプロジェクト（またはプロジェクトのファミリー）だけで作業することを選択することはありません。上記の設定は設定ですが、設定に一致する作業がない場合、システムは、作業要求時に実行する必要があることを送信するように設計されています。

BOINC 向け F@H はまだ存在しないようです。なお、かつては Sony 製の Android 向け Folding@home があったとか。

そこで、emerge で dev-libs/openssl-compat や sci-biology/foldingathome を入れました……が、その後も同じエラーに遭遇。うーむ。

蛇足

単純に Sabayon のビルドサーバの最新の Portage の設定を追いかけるだけなら /opt/sabayon-build に cd して git pull とかでも良いのかな？

emerge で dev-libs/openssl-compat と sci-biology/foldingathome を導入

ソフトウェアの導入

equo install dev-libs/openssl-compat --ask
equo install sci-biology/foldingathome --ask
equo install dev-util/patchelf --ask
emerge dev-libs/openssl-compat --ask
emerge sci-biology/foldingathome --ask
equo rescue spmsync --ask

spmsync
Update Entropy installed packages repository merging Source Package Manager changes.

Sabayon における emerge の autounmask 関連作業時の不調の回避

Sabayon では /etc/portage が /opt/sabayon-build/conf/intel/portage へのシンボリックリンクですが、これが原因となり /etc/portage 内の設定ファイルについて dispatch-conf（もしくは equo conf update ¹）が認識してくれません。この場合 dispatch-conf /opt/sabayon-build/conf/intel/portage とすることで問題を回避可能でした。

例

7.5.1-r3

emerge sci-biology/foldingathome --autounmask --autounmask-write --ask
dispatch-conf /opt/sabayon-build/conf/intel/portage
emerge sci-biology/foldingathome --ask
equo rescue spmsync --ask
