For TensorRT to work, we need at last 2 features.
A semaphore for trt compilation. This is to prevent multiple processes from compiling at the same time and go OOM.
A caching mechanism for compiled model. First, this remove the need for each process to perform compilation, saving 1-2 minutes per process. Second, this speeds up subsequent runs.
