RHEL on Power10 で llama.cpp (言語モデル) を動かす

#### はじめに

以前、[音声認識モデルをPower10上で稼働確認](https://qiita.com/c_u/items/ac37833a9a4687cf79a2) した後、CPUで稼働可能な言語モデル探したところ llama.cpp が存在していることを見つけました。こちらを Power10 上で動かしてみたログです。

https://github.com/ggerganov/llama.cpp


llama.cpp には  "Whisper.cpp" に記載があった "VSX intrinsics support for POWER architectures" のコメントが見られないため、2024/4時点ではまだ PowerISA 非対応かもしれません。


---

#### 実行環境

IBM Power S1022 （CPUのみです）
RHEL 9.2 (LPARに対して CPU 4 core, Memory 32GB 割り当て)
(インターネット接続環境)

 Building a website can be done in 10 simple steps:

Step 1: Define your website's purpose and goals.
Step 2: Choose a domain name and web hosting provider.
Step 3: Plan your website's layout and design.
Step 4: Create your website's content.
Step 5: Build your website using a website builder or coding.
Step 6: Test your website for functionality and usability.
Step 7: Launch your website and make any necessary updates.
Step 8: Optimize your website for search engines.
Step 9: Promote your website through various marketing channels.
Step 10: Monitor and update your website regularly to ensure it stays relevant and up-to-date.

These are the basic steps involved in building a website, but the process may vary depending on the complexity of the website and the individual's level of expertise. [end of text]
