Help connecting over ssh

[SergeyV]

Dear DevCloud team:

I am unable to ssh in with the key file I was given. 

e.g. : I try this command:

ssh -v -i .ssh/devcloud-access-key-151381.txt guest@ssh.devcloud.intel.com 

I have also tried replacing guest with the username. Could you tell me how I can try to proceed?

Thank you!

Sergey

Hi,

Thank you for posting in the intel communities.

Please follow the below steps for automated installation:

1. Download this simple Windows batch script https://devcloud.intel.com/oneapi/static/assets/install_cygwin.bat

2. Extract the downloaded script (keep it as default c:\cygwin64)

3. Now open the Cygwin64 terminal, which looks like below.

4. Now go to the below path and add the setup-devcloud-access-xxxxxx.txt to that path. (Connect with Cygwin | Intel® DevCloud)

path: C:\cygwin64\home\<User_name>

file: setup-devcloud-access-xxxxxx.txt

        

5. Open the Cygwin terminal and follow the below commands.

$ ls

setup-devcloud-access-xxxxxx.txt

$ bash ./setup-devcloud-access-xxxxxx.txt

6. Connect to the DevCloud using( ssh devcloud)

ssh devcloud

Connect to the DevCloud via proxy:

1. Before connecting via proxy, we need to modify the config file. config file is loacted in the below path

path:C:\cygwin64\home\<User_name>\.ssh

In the above path, open the config file and modify it as shown in the below pic.

add: nc -x proxy-us.intel.com %h %p (after ProxyCommand)

If this resolves your issue, make sure to accept this as a solution. This would help others with similar issue. Thank you

Hi Jaideep,

 Thanks! Your instructions work. I used it with WSL. I had an older config file just with the key info (not the batch script). For some reason it didn't work with ssh. I downloaded the setup file from https://devcloud.intel.com/oneapi/documentation/connect-with-ssh-windows-cygwin/ and it works now! For upload, I read from instruction about using scp file devcloud: in separate terminal. Thanks. Could you tell me how I can find out the GPU card type? Are there different types of GPUs available? For example if "qsub -I -l nodes=1:gpu:ppn=2 -d" command is used what is the GPU type that is provided on the instance? I cannot tell from lspci -v output. Also, is it possible to (apt) install the programs htop and screen?

Thanks again,

Sergey

Hi,

Glad to know that your issue is resolved.

To check specific GPU nodes, please use below command:

pbsnodes | grep -i gpu -A 1 -B 4

If you are already in the GPU node and want to check GPU information, please use the below command.

clinfo

or

sycl-ls

Since DevCloud doesn't have sudo permissions, we can't install any packages using apt. 

Please let us know whether we can close this thread.

Thanks,

Jaideep

Thank you! I still can't tell the GPU name (e.g. Arc series, NV card, etc). For example,

pbsnodes command returns for each node 'properties = xeon,cfl,e-2176g,ram64gb,net1gbe,gpu,gen9' or similar, which has the CPU type but not the GPU model. From clinfo on the instanced node, I see the device vendor ID and driver name. Any way to tell the card family info from this?

Other than that, I have no other questions and you can close the thread. Thanks!

Hi,

DevCloud supports two types of integrated GPUs: Intel® UHD Graphics for 11th Gen and Intel® UHD Graphics P630. (There are no discrete gpus available on DevCloud)

With the below command we can access all the gpu nodes.

pbsnodes | grep -i gpu -A 4 -B 4

Core cpu's have: Intel® UHD Graphics for 11th Gen

Xeon cpu's have: Intel® UHD Graphics P630

Please let us know whether we can close this thread.

Thanks,

Thank you, I got it. Do you know where I can try to connect to a machine with discrete Intel GPU? Yes, you can close the thread. Thank you.

Hi,

Sorry to say this, but currently on DevCloud there are no discrete GPUs available. If you need any additional information, please post a new question as this thread will no longer be monitored by Intel.

Have a great day ahead.
