Hi I am reading Habitat research paper.

I wonder what the meaning of varing kernel is. I thought the GPU kernel is a collection of instructions that run in parallel, is that right?

Can you give me an example of this phrase? 'some DNN operations are implemented using different GPU kernels on different GPUs '

Thank you for taking the time to read.

Hi @geoffxy,

Great work here. I am quite interested in your project and try to reproduce from my side. Hower hit the error in the titel, I suspect that it may be caused by incompetible between CUPTI and NVIDIA driver version, I am wondering if could share you experiment setup here, mostly the host side, are you still using 18.04, what the nvidia driver version, did you use nvidia-docker2 or nvidia-container-runtime? what is your docker version?

As mine, I am using 18.04 as host, driver 470.103.01, nvidia-docker2, docker 20.10.12.

Thanks, Liang

Hi! Thanks for your perfect job.

It's easy to understand to measure the execution time in the forward pass. But in the backward pass, how Habitat does? I think it is an undoubtedly different processor, right?

@geoffxy Hope for your reply soon!

Hi, I am reproducing the experiments in Habitat now. This is an interesting work and it's very convenient to run Habitat and process the results using the following two scripts.

bash habitat/experiments/gather_raw_data.sh  <target_device>
bash habitat/experiments/process_raw_data.sh

Due to the limitation of GPU resources, I can not access all GPU models listed in the paper and only test it on V100, P100 and T4. But the prediction error is quite large, compared to that shown in the paper. You can check the results here.

Basically, the setting I used follows habitat/docker/Dockerfile. Here are some of my experiment settings that may be different from yours:

• CUDA driver version: 455.32.00,
• I do not mount the user account on the host machine into the container

So,

1. Is there any hyper-parameter I need to tune to get a better prediction error ? 2.Can you share the cross-GPU prediction error between each pair of GPUs or just the output of habitat/experiments/process_raw_data.sh? Fig 3 in the paper only shows the results "averaged across all other “origin” GPUs".
2. Will the setting differences listed above affect the prediction error ? Or any other possible reasons ?

Thanks.

when running "install-dev.sh", hit below error:

CMake Error at CMakeLists.txt:22 (pybind11_add_module): Unknown CMake command "pybind11_add_module".

-- Configuring incomplete, errors occurred!

The default configuration on my OS and current directions in README may lead to a CUPTI_ERROR_INSUFFICIENT_PRIVILEGES when using CUPTI inside the container.

The example log is attached below:

My solution: Adding options nvidia "NVreg_RestrictProfilingToAdminUsers=0" to /etc/modprobe.d/nvidia-kernel-common.conf and reboot.

Hi, I am following the steps here to reproduce habitat. When running setup.sh to build the image, the following error occurs

Step 14/19 : RUN gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4

gpg: WARNING: unsafe permissions on homedir '/root/.gnupg'

Does it mean the keyserver ha.pool.sks-keyservers.net is not accessible now?

I wonder whether it is necessary to duplicate the user account on the host machine into the container. With a root account in the container, I can access everything mounted from the host machine. What problem does it cause?

Looking forward to your reply. Thanks.
