Frequently asked questions

1. Q: Do I have to use an NVIDIA GPU to install it?

A: Yes, if you want to install the GPU version, an NVIDIA GPU is required.

2. Q: I ran cat /etc/redhat-release and it shows “NFS Server release 3.2 (RTM1)” — the server is running an NFS-based server OS. Can I install it on this system?

A: Yes, you can install it. Run lscpu to check — as long as the CPU is x86_64, it will work.

3. Q: What if the other server is running CentOS 7.6 — is that okay?

A: Yes, that's fine. You can follow our CentOS 7.9 installation guide.

4. Q: Is there a separate installation guide for the single-machine version with a GPU, on Windows 11?

A: Yes — it's in our installation guide: http://mcloud-doc.lonxun.com/wiki/en/pwstudio/win11_gpu

5. Q: What's the difference between installing on an HPC cluster and installing on a single workstation?

A: PWstudio can only be installed on a single machine — that is, on a workstation. If you're deploying to a cluster, it's still installed on one of the cluster's compute nodes.

6. Q: After installing the three base environment pieces (GPU driver, Docker, and nvidia-container-toolkit), which directory should I be in for the PWstudio step that imports the image? (Does it have to be the directory I'm currently in? I'm currently in the nvidia-container-toolkit directory — does that matter?)

A: It doesn't matter. This step just downloads the image to your local server and has no directory requirement. The image ends up in Docker's default location, usually /var/lib/docker.

7. Q: Can qflow only be authenticated by logging in through the web page?

A: Yes, both qflow and qstudio require logging in through the browser. If you need to submit jobs directly via the command line through pwmat, you'll have to log into the command-line interface using terminal software such as Xshell. For details, see the PWstudio installation guide.

If you can include a screenshot or the exact text of the error message, along with which system you're using (e.g. CentOS 7.9 / Rocky 8.10 / Ubuntu 24.04 / Windows 11), it'll be much easier for others to help you track down the problem quickly.
