Issue

Multiple errors regarding the following buffers not being used.

    vk::Buffer *mStagingBuffer;
    vk::DeviceSize mSize;

src/gpt4all/gpt4all-backend/llama.cpp-mainline/kompute/src/include/kompute/operations/OpTensorSyncDevice.hpp:61: error: private field 'mPrimaryBuffer' is not used [-Werror,-Wunused-private-field]

    vk::Buffer *mPrimaryBuffer;
                ^

What I wound up doing is changing ALWAYS OWNED RESOURCES from private to to public.

OpTensorSyncDevice.hpp

  private:
    // -------------- ALWAYS OWNED RESOURCES
    std::vector<std::shared_ptr<Tensor>> mTensors;
    vk::Buffer *mPrimaryBuffer;
    vk::Buffer *mStagingBuffer;
    vk::DeviceSize mSize;

It at least allows it to compile. But I'm no paragon of C++. Comments?

Information

• The official example notebooks/scripts
• My own modified scripts
