This script wraps ci/run.sh:
* If <tmp_dir> is a ramdisk, you can reduce writes to your SSD. If <tmp_dir> is not a ramdisk, keep in mind that total writes will increase by the size of <cache_dir>.
    (openllama_3b_v2: quantized models are about 30GB)
* Persistent model and data files are synced to and from <cache_dir>,
    excluding generated .gguf files.
    (openllama_3b_v2: persistent files are about 6.6GB)
* <cache_dir> defaults to  ~/.cache/llama.cpp
