+## Inference on TensorFlow BERT and ResNet50 models
+This directory contains steps and artifacts to run inference with TensorFlow BERT and ResNet50
+sample workloads on Gramine. Specifically, both these examples use pre-trained models to run
+inference.
+
+### Bidirectional Encoder Representations from Transformers (BERT):
+BERT is a method of pre-training language representations and then use that trained model for
+downstream NLP tasks like 'question answering'. BERT is an unsupervised, deeply bidirectional system
+for pre-training NLP.
+In this BERT sample, we use **BERT-Large, Uncased (Whole Word Masking)** model and perform int8
+inference. More details about BERT can be found at https://github.com/google-research/bert.
+
+### Residual Network (ResNet):
+ResNet50 is a convolutional neural network that is 50 layers deep.
+In this ResNet50 (v1.5) sample, we use a pre-trained model and perform int8 inference.
+More details about ResNet50 can be found at https://github.com/IntelAI/models/tree/icx-launch-public/benchmarks/image_recognition/tensorflow/resnet50v1_5.
+
+## Pre-requisites
+- Upgrade pip/pip3.
+- Install TensorFlow using ``pip install intel-tensorflow-avx512==2.4.0``.
+
+## Build BERT or ResNet50 samples
+- To build BERT sample, do ``cd BERT``. To build ResNet50 sample, do ``cd ResNet50``.
+- To clean the sample, do ``make clean``
+- To clean and remove downloaded models and datasets, do ``make distclean``
+- To build the non-SGX version, do ``make PYTHONDISTPATH=path_to_python_dist_packages/``
+- To build the SGX version, do ``make PYTHONDISTPATH=path_to_python_dist_packages/ SGX=1``
+- Typically, ``path_to_python_dist_packages`` is ``/usr/local/lib/python3.6/dist-packages``, but can
+change based on python's installation directory.
+
+**WARNING:** Building BERT sample downloads about 5GB of data.
+
+## Run inference on BERT model
+- To run int8 inference on ``gramine-sgx`` (SGX version):
+```
+OMP_NUM_THREADS=36 KMP_AFFINITY=granularity=fine,verbose,compact,1,0 taskset -c 0-35 gramine-sgx \
+./python models/models/language_modeling/tensorflow/bert_large/inference/run_squad.py \
+--init_checkpoint=data/bert_large_checkpoints/model.ckpt-3649 \
+--vocab_file=data/wwm_uncased_L-24_H-1024_A-16/vocab.txt \
+--bert_config_file=data/wwm_uncased_L-24_H-1024_A-16/bert_config.json \
+--predict_file=data/wwm_uncased_L-24_H-1024_A-16/dev-v1.1.json \
+--precision=int8 \
+--output_dir=output/bert-squad-output \
+--predict_batch_size=32 \
+--experimental_gelu=True \
+--optimized_softmax=True \
+--input_graph=data/asymmetric_per_channel_bert_int8.pb \
+--do_predict=True --mode=benchmark \
+--inter_op_parallelism_threads=1 \
+--intra_op_parallelism_threads=36
+```
+- To run int8 inference on ``gramine-direct`` (non-SGX version), replace ``gramine-sgx`` with
+``gramine-direct`` in the above command.
+- To run int8 inference natively (outside Gramine), replace ``gramine-sgx ./python`` with
+``python3`` in the above command.
+
+## Run inference on ResNet50 model
+- To run inference on ``gramine-sgx`` (SGX version):
+```
+OMP_NUM_THREADS=36 KMP_AFFINITY=granularity=fine,verbose,compact,1,0 taskset -c 0-35 gramine-sgx \
+./python models/models/image_recognition/tensorflow/resnet50v1_5/inference/eval_image_classifier_inference.py \
+--input-graph=resnet50v1_5_int8_pretrained_model.pb \
+--num-inter-threads=1 \
+--num-intra-threads=36 \
+--batch-size=32 \
+--warmup-steps=50 \
+--steps=500
+```
+- To run inference on ``gramine-direct`` (non-SGX version), replace ``gramine-sgx`` with
+``gramine-direct`` in the above command.
+- To run inference natively (outside Gramine), replace ``gramine-sgx ./python`` with
+``python3`` in the above command.
+
+## Notes on optimal performance
+Above commands are for a 36 core system. Please set the following options accordingly for optimal
+performance:
+
+- Assuming that X is the number of cores per socket, set `OMP_NUM_THREADS=X`,
+  `intra_op_parallelism_threads=X` for BERT and `num_intra_threads=X` for ResNet50.
+- Specify the whole range of cores available on one of the sockets in `taskset`.
+- If hyperthreading is enabled: use ``KMP_AFFINITY=granularity=fine,verbose,compact,1,0``
+- If hyperthreading is disabled: use ``KMP_AFFINITY=granularity=fine,verbose,compact``
+- Note that `OMP_NUM_THREADS` sets the maximum number of threads to
+  use for OpenMP parallel regions, and `KMP_AFFINITY` binds OpenMP threads
+  to physical processing units.
+- The options `batch-size`, `warmup-steps` and `steps` can be varied for ResNet50 sample.
+- To get the number of cores per socket, do ``lscpu | grep 'Core(s) per socket'``.
+
+## Performance considerations
+### CPU frequency scaling
+
+Linux systems have CPU frequency scaling governor that helps the system to scale the CPU frequency
+to achieve best performance or to save power based on the requirement. To achieve the best
+performance, please set the CPU frequency scaling governor to `performance` mode.
+
+```bash
+for ((i=0; i<$(nproc); i++)); do
+    echo 'performance' > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor;
+done
+```
+
+### Manifest options for performance
+
+- Preheat manifest option pre-faults the enclave memory and moves the performance penalty to
+Gramine-SGX startup (before the workload starts executing). To use the preheat option, make sure
+that `sgx.preheat_enclave = true` is added to the manifest template.
+
+### Memory allocator libraries
+
+TCMalloc and mimalloc are memory allocator libraries from Google and Microsoft that can help
+improve performance significantly based on the workloads. Only one of these
+allocators can be used.
+
+#### TCMalloc
+
+(Please update the binary location and name if different from default.)
+- Install tcmalloc: `sudo apt-get install google-perftools`
+- Modify the manifest template file:
+    - Add `loader.env.LD_PRELOAD = "/usr/lib/x86_64-linux-gnu/libtcmalloc.so.4"`
+    - Append below entries to `sgx.trusted_files`:
+        - `"file:/usr/lib/x86_64-linux-gnu/libtcmalloc.so.4"`
+        - `"file:/usr/lib/x86_64-linux-gnu/libunwind.so.8"`
+- Save the manifest template and rebuild this example.
+
+#### mimalloc
+
+(Please update the binary location and name if different from default.)
+- Install mimalloc using the steps from https://github.com/microsoft/mimalloc
+- Modify the manifest template file:
+    - Add the `/usr/local` FS mount point:
+        - `fs.mount.usr_local.type = "chroot"`
+        - `fs.mount.usr_local.path = "/usr/local"`
+        - `fs.mount.usr_local.uri = "file:/usr/local"`
+    - Add `loader.env.LD_PRELOAD = "/usr/local/lib/mimalloc-1.7/libmimalloc.so.1.7"`
+    - Append below entry to `sgx.trusted_files`:
+        - `"file:/usr/local/lib/mimalloc-1.7/libmimalloc.so.1.7"`
+- Save the manifest template and rebuild this example.
