About Genta Technology

We are a small team of students passionate about addressing key concerns in AI such as energy, privacy, on-premise, and on-edge computing. Our flagship product is the Genta Inference Engine, which allows enterprises to deploy open-source models on their own servers, with 3-4x higher throughput. This can reduce operational costs by up to 80%, as a single server optimized by our engine can handle the workload of four standard servers.

Prerequisites

• CMake 3.14 or above

Download from https://cmake.org/download/.

• A C++17-compatible compiler

- For Windows, Visual Studio 2019/2022 (MSVC) or MinGW-w64 with GCC 7+. - For other platforms, an equivalent compiler supporting C++17.

• Git (optional, but recommended for cloning and submodule management).
• OpenSSL, CURL

- On Windows, you can place the pre-built bins/headers inside external/openssl and external/curl (or anywhere you prefer, just ensure CMakeLists.txt sees them).

• (Optional) Vulkan SDK if you plan to use the Vulkan-based inference engine.

Cloning and Preparing the Repository

• Clone the repository:

git clone https://github.com/Genta-Technology/Kolosal.git
   cd KolosalAI

• Update submodules:

If any external libraries are handled as Git submodules, initialize them:

git submodule update --init --recursive

• Pull Git LFS:

git lfs install
   glt lfs pull

• Check external dependencies:

Ensure the external folder contains: - curl with include/, lib/, and bin/ (Windows). - openssl or that OpenSSL is installed system-wide. - The genta-personal engine in place if not fetched from elsewhere.

• Folder structure verification:

Verify that folders like nativefiledialog-extended, imgui, etc., are present inside external/.

Configuring the Project with CMake

You can perform either an in-source or out-of-source build, but out-of-source is recommended. Below is an example of an out-of-source build:

• Create a build folder:

mkdir build
   cd build

• Run CMake:

By default, this will generate build files for your platform’s default generator (e.g., Visual Studio solution files on Windows, Makefiles on Linux, etc.):

cmake -S .. -B . -DCMAKEBUILDTYPE=Release

or explicitly (for Visual Studio multi-config):

cmake -S .. -B . -G "Visual Studio 17 2022" -A x64

- -DDEBUG=ON can be used if you want to build a debug version:

cmake -S .. -B . -DCMAKEBUILDTYPE=Debug -DDEBUG=ON

• Check for any errors during configuration, such as missing libraries or headers. Resolve them by installing or copying the required dependencies into the correct location.

Building the Application

After successful configuration:

• On Windows with Visual Studio:

Open the generated .sln file inside build/ and build the solution. Or build from the command line using:

cmake --build . --config Release

• On other platforms (e.g., using Make or Ninja):

cmake --build . --config Release

Note:

The POST_BUILD commands in CMakeLists.txt will copy the necessary DLLs, fonts, assets, and models into the final output folder (e.g., build/Release/ or build/Debug/, depending on your generator).

Running the Application

• Locate the output:

Once the build completes, you should find the executable (e.g., KolosalDesktop.exe on Windows) in a directory such as: - build/Release/ (Visual Studio). - build/ (single-config generators like Make).

• Check for required files:

The post-build commands should have copied: - Fonts (/fonts folder next to the exe). - Assets (/assets folder next to the exe). - Models (/models folder next to the exe). - OpenSSL and InferenceEngine DLLs (Windows). - cURL DLL(s) (Windows).

Make sure these folders and files are present in the same directory as KolosalDesktop.exe.

• Double-click or run from terminal:

cd build/Release
   ./KolosalDesktop.exe

• Enjoy Kolosal AI!

Troubleshooting

• OpenSSL or CURL not found

- Make sure you have them installed or placed in external/openssl and external/curl respectively. - Check environment variables like OPENSSLROOTDIR or CURLROOTDIR if needed. - Update CMAKEPREFIXPATH if you’re placing these libraries somewhere non-standard.

• InferenceEngine libraries not found

- Verify the path external/genta-personal/lib actually contains InferenceEngineLib.lib or InferenceEngineLibVulkan.lib (on Windows). - Adjust find_library paths in CMakeLists.txt if your structure differs.

• Missing Vulkan SDK

- If you plan to use the Vulkan-based inference engine, ensure Vulkan SDK is installed and available in your PATH or that CMake can find it.

• ImGui not found

- Ensure external/imgui folder is not empty. - If you see compilation errors referencing ImGui headers, check that targetincludedirectories in CMakeLists.txt still points to the correct path.

• Resource or Icon issues on non-Windows

- The assets/resource.rc file is Windows-specific. For Linux/macOS builds, you can comment out or remove references to .rc if they cause issues.

• Runtime errors due to missing DLLs or dynamic libraries

- Confirm that the post-build step copies all required .dll files next to the executable. - On Linux/macOS, ensure .so/.dylib are in the library search path or same folder.
