Hey, I’m thinking of trying out HCC with my H800. Does anyone know if the H800 supports HCC?
And can I use the documentation from this repo to turn on CC mode for my H800?Like these docs: NVIDIA Trusted Computing Solutions - NVIDIA Docs.
Also, I wanna know if successfully completing GPU Attestation means that HCC is already up and running? Thank you !
NVIDIA Confidential Computing is a built-in security feature of Hopper that makes NVIDIA H800 the world’s first accelerator with confidential computing capabilities. Users can protect the confidentiality and integrity of their data and applications in use while accessing the unsurpassed acceleration of H800 GPUs.
And can I use the documentation from this repo to turn on CC mode for my H800?
If by “this repo” you mean GitHub - NVIDIA/gpu-admin-tools: GPU Admin Tools. Includes Confidential Computing controls for H100, and other functionality, then yes.
I wanna know if successfully completing GPU Attestation means that HCC is already up and running?
For the most part, yes. You may still need to set the driver’s ReadyState to signal that you are ready to perform real work on the GPU, or the Verifier software may do that for you.

Thank you so much for answering my question! “This repo” I’m talking about is this one: GitHub - NVIDIA/nvtrust: Ancillary open source software to support confidential computing on NVIDIA GPUs. It includes some guide documents, like this one: Confidential Computing Deployment Guide. So, I can also use these documents to enable the CC mode on my H800, right?
Are there any benchmarks or something like that to test if the H800’s CC mode is fully enabled?
Yes, you could use those documents. To test whether CC mode is enabled, you could try nvidia-smi conf-compute -f

You can do simple H2D / D2H transfers and see the performance drop due to CPU-side encryption and decryption.
