Given that InferenceSession::Run() is guaranteed to be thread-safe
meaning multiple threads can call this function concurrently,
TRT EP needs to carefully take care of concurrency here, if not,
following concurrent issue might happen:
- It's suggested that to perform inference concurrently in multiple
streams, use one trt execution context per stream.
In the design of TRT EP (Not apply per-thread context implementation)
and if multiple threads are calling InferenceSession::Run()
concurrently, the trt execution context instance is shared by all the
threads and each thread aquires different stream from ORT.
So TRT EP will end up having one trt execution context using multiple
streams which is not suggested.
But, since the whole compute_func() is protected by the lock and if
cudaStreamSynchronize() is enforced here, one trt execution context per
stream is guaranteed.
Therefore, TRT EP needs to call cudaStreamSynchronize() at
compute_func() which means to wait until stream has completed all
operations to prevent the concurrent

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.
ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
