View source for 2024 llama.cpp 7840u

I briefly had a Macbook M3 Max with 64GB. It was pretty good at running local LLMs, but couldn't stand the ergonomics and not being able to run Linux, so returned it.

I picked up a Thinkpad P16s with an AMD 7840 to give Linux hardware a chance to catch up with Apple silicon. It's an amazing computer for the price, and can run LLMs. Here's how I set up llama.cpp to use ROCm.

Install ROCm, set an env variable for the 780m: <code>export HSA_OVERRIDE_GFX_VERSION=11.0.0</code>

clone llama.cpp and compile it:

<code>make -j16 LLAMA_HIPBLAS=1 LLAMA_HIP_UMA=1 AMDGPU_TARGETS=gfx1030 DLLAMA_HIP_UMA=
ON</code>

run it like this:

<code>./main -m /home/vid/jan/models/mistral-ins-7b-q4/mistral-7b-instruct-v0.2.Q4_K_M
.gguf -p "example code for a lit Web Component that reverses a string" -n 50 -e 
-ngl 16  -n -1</code>

  simple example code for a lit Web Component that reverses a string input
 
 Hi there! Here's a simple example of a Lit Web Component that reverses a string input:
 
 ```javascript
 import { Component, html, css } from 'lit';
 
 class ReverseString extends Component {
   static styles = css`
     input {
       padding: 10px;
       margin-bottom: 20px;
     }
   `;
 
   static properties = {
     value: { type: String }
   };
 
   constructor() {
     super();
     this.value = '';
   }
  
   render() {
     return html`
       <style>${this.constructor.styles}</style>
       <input @input=${this._handleInputChange} value=${this.value} type="text">
       < p>Reversed string: ${this._reverseString(this.value)}< /p>
     `;
   }
  
   _reverseString(str) {
     return str.split('').reverse().join('');
   }
 
   _handleInputChange(event) {
     this.value = event.target.value;
   }
 }
 
 customElements.define('reverse-string', ReverseString);
 ```
 
 In this example, we define a custom Web Component called `reverse-string` that uses Lit for rendering and handling user input. The `ReverseString` class defines a render method that returns an HTML template with an input field and a paragraph that displays the reversed string. The component also defines a `_reverseString` method that reverses a given string using the `split`, `reverse`, and `join` array methods, and a `_handleInputChange` method that updates the component's value whenever the input changes. Finally, we use the `customElements.define` method to register our component with the browser.
 
 You can use this component in your HTML like this:
 
 ```html
 <reverse-string></reverse-string>
 ``` [end of text]
