Limitations and recommended settings#
This section provides information on software and configuration limitations.
Note
For ROCm on Instinct known issues, refer to AMD ROCm DocumentationFor OpenMPI limitations, see ROCm UCX OpenMPI on Github
6.3.4 release known issues#
Intermittent script failure may be observed while running Stable Diffusion training workloads using TensorFlow
Intermittent script failure may be observed while running Triton examples
Increased memory consumption may be observed while running TensorFlow Resnet50 training workloads
Performance drop may be observed while running ONNX Runtime scripts with INT8 precision
Script hang may be observed while running RetinaNet training workloads with batch size 32 using TensorFlow
Performance drop may be observed while running Bert training workloads across multiGPU configurations
Black Image may be generated/observed while running Stable Diffusion 2.1 FP16 using Pytorch
WSL specific issues#
Intermittent application crash or driver timeout may be observed while using ComfyUI with WSL2 on some AMD Graphics Products, such as the Radeon™ RX 7900 Series
Intermittent script hang may be observed while running RetinaNet training workloads using TensorFlow
Intermittent application freeze may be observed when running ChatGLM workloads with Onnx Runtime and MIGraphX using fp16 or fp32 precision
Intermittent application crash or driver timeout may be observed while running Blender Cycles rendering along with Pytorch Inception V3 training scripts
Intermittent build error may be observed when running ROCM/HIP workloads using CMake. Users experiencing this issue are recommended to replace the Native Linux library filename (for example
libhsa-runtime64.so.1.14.60304) in/opt/rocm/lib/cmake/hsa-runtime64/hsa-runtime64Targets-relwithdebinfo.cmakewith the WSL library filenamelibhsa-runtime64.so.1.14.0as a temporary workaround.
Important!
Radeon™ PRO Series graphics cards are not designed nor recommended for datacenter usage. Use in a datacenter setting may adversely affect manageability, efficiency, reliability, and/or performance. GD-239.
Important!
ROCm is not officially supported on any mobile SKUs.
Multi-GPU configuration#
Windows Subsystem for Linux (WSL)#
WSL recommended settings and limitations.
WSL recommended settings#
Optimizing GPU utilization
WSL overhead is a noted bottleneck for GPU utilization. Increasing the batch size of operations will load the GPU more optimally, reducing time required for AI workloads. Optimal batch sizes vary by model, and macro-parameters.
ROCm support in WSL environments#
Due to WSL architectural limitations for native Linux User Kernel Interface (UKI), rocm-smi is not supported.

Running PyTorch in virtual environments#
Running PyTorch in virtual environments requires a manual libhsa-runtime64.so update.
When using the WSL usecase and hsa-runtime-rocr4wsl-amdgpu package (installed with PyTorch wheels), users are required to update to a WSL compatible runtime lib.
Solution:
Enter the following commands:
location=`pip show torch | grep Location | awk -F ": " '{print $2}'`
cd ${location}/torch/lib/
rm libhsa-runtime64.so*
cp /opt/rocm/lib/libhsa-runtime64.so.1.2 libhsa-runtime64.so
