Visual Studio Code Login
Berry Spitsberg
If you log in to the WEB IDE, you should be prompted with the option for 2 factor authentication and from there you can set this up. You need to install the authenticator app, and that generates the 6 digit code.
Two step was not enabled and I can log into the web IDE fine. When logging into the IDE VS and clicking enter when asked for a 6 digit number, the login still fails with the following error. This may be related to some other issue, such as being behind a firewall with ports blocked though.
I am facing multiple popups of login into bitbucket. I face almost 6-7 popups every time I use VS code and this is getting very annoying. Despite trying various methods. I have failed in getting rid of these popups.
The Azure Account extension provides a single Azure sign in and subscription filtering experience for all other Azure extensions. It makes Azure's Cloud Shell service available in VS Code's integrated terminal.
Note: The Azure Cloud Shell feature has moved to the Azure Resources extension. Apart from moving codebases, the feature is the same from a users perspective. Authentication for the Cloud Shell feature is now handled by the VS Code built-in Microsoft authentication provider, which means you may have to login upon first use of the migrated feature.
Azure Cloud Shell instances can be started via the terminal view in VS Code. To begin, click thedropdown arrow in the terminal view and select from either Azure Cloud Shell (Bash) orAzure Cloud Shell (PowerShell).

So when I run this block of code, to PRINT the output of the SYSDATE function, I get the date with the date format I want, and I get the amount of time it took to execute, all because my session as TIMING and SERVEROUTPUT enabled.
Jeff, does this extension support 10g database dbms output ? sql developer had this issue due to jdeveloper limitation (i read it somewher). Another question is do you plan on retaining pin query results, this was a very good feature.
Thanks for your generous comments that are always helpful, mind you the startup script parameter breaks the run in SQLcl. SQLcl starts in the terminal windows but no longer executes the login.sql script, removing the parameter value fixes SQLcl no longer running the login.sql, I already created a post in the extension forum.
Visual studio code is an advanced IDE (Integrated Development Environment) which has many useful extensions for building and running your code on Perlmutter. There are many useful extensions supported by Microsoft for common HPC tools like Python, C/C++, as well as many user contributed extensions.
Connecting to Perlmutter with VSCode Remote - SSH is similar to connecting to any other Linux computer. The most up to date instructions can be found on the Remote SSH extension site. By default VSCode will connect to a Perlmutter login node which can be used for software development but should not be used for computation. For larger computations or to connect to GPUs you should get an allocation on a compute node.
In your VSCode window you'll also need to update two settings, the maxReconnectionAttempts will help to disconnect when the compute node allocation is over and useFlock needs to be set to false as file locking (flock) is not supported by the way $HOME directories are mounted on compute nodes.
When connecting you'll first connect to a Perlmutter login node and request and interactive allocation from Slurm with salloc. The following salloc line requests one GPU node for 60 minutes. Remember to change `m0000`` to the account that you want to charge hours from.
Once you have an allocation copy the the node name starting with nid and go through the normal steps to connect to a remote ssh host using the hostname with nid as the hostname you want to connect to.
The best way to use Visual Studio Code (VS Code) and longleaf is through longleaf's Open On Demand (also called onDemand or OOD).Once you log into OOD, start an interactive session for Longleaf Desktop (or Longleaf Desktop with GPU, if you need a GPU). Once the job starts running and you have launched it, select Applications in the upper left, then Development in the drop down menu and Visual Studio Code:
If using OnDemand's VS Code will not work for what you need to do, please send email to rese...@unc.edu and let us know what your needs are outside of what OnDemand can provide. We will add your requirements to the enhancement request list for OnDemand.
To use VS Code with longleaf, you will need to manage and use two different types of connections with longleaf. The first one you will need is a connection to longleaf.unc.edu, which is longleaf's login node. This is where you can do based file editing, file manipulations and quick tests, but not where your extecute your computationally-intensive commands, nor use cpptools. Long computations need to be executed on a compute node. Cpptools has an issue that causes unexplainably high cpu surges. Tying up the login node with an intensive command can result in degradation of access & performance to the longleaf login node for other users and is an abuse of your longleaf privileges. Connecting to a compute node via VS Code requires you to submit a job to SLURM to request a compute node (more about that later).
In the first section we will connect to a Longleaf login node from VS Code and then in the second section we will show how to connect to a Longleaf compute node from VS Code. These two sections are for users who intend to use both. Experienced VS Code users who intend to only use a compute node connection can skip to the discussion in Section 3.
If you have other ssh key files you want to keep separate, choose a name other than the default. If you do not,press Enter to save the key in default location. The rest of this document uses the default name.
Open the authorized_keys file with your favorite linux editor and copy and paste the contents of your local id_rsa.pub file (from the previous step) into the authorized_keys file. You can have multiple key entries in a single authorized_keys file.If you already have an authorized_keys file append the contents of your local id_rsa.pub file to the end. Make sure each key in the authorized_keys file is on its own line and there are no line breaks within a key entry. Save and exit authorized_keys.
For User put your ONYEN where it says onyen. For IdentityFile put the path to the local private key you created in step 2 above. If your VS Code ssh configuration file has existing entries append the one for Longleaf to the end.
Be aware, if you execute any code using this VS Code Longleaf session, it will run on the Longleaf login node that your VS Code session is connected to. For this reason, you will want to restrict yourself to basic editing and running only simple codes in this kind of VS Code session. Use the compute node section below to run your calculations using VS Code.
A Longleaf bash terminal session appear at the bottom of the VS Code window. In this terminal, submit a SLURM job for an interactive bash session with the time and memory your job will need. For example:
In this current Longleaf VS Code window choose Help from the upper menu and then choose Show All Commands from the pull-down menu. [Note: You must do this from this same Longleaf VS Code window: You will get the error message Could not establish conection to... if you try it from a VS Code window that is not connected to longleaf.]
When you are finished, click on the Longleaf Remote icon in the bottom left corner and choose Close Remote Connection.Note: If you close the remote connection to the login node, it will automatically close this remote connection to the compute node.
If you already have an interactive job running (that you started outside VS Code in an ssh session), then you can skip logging into the login node in VS Code and go straight to opening a new SSH connection to that compute node's hostname. Note that exiting the interactive session (from the ssh session that submitted srun to create the interactive session on longleaf) will also kill the VS Code connection to the compute node).
Open Beta Release: The cloud IDE and AsyncAPI implementation support are in open beta. Any use of Anypoint Code Builder in its beta state is subject to the applicable beta services terms and conditions, available from the IDE.
Anypoint Code Builder is built from the Anypoint Extension Pack for Visual Studio Code. Both the desktop and cloud IDEs for Anypoint Code Builder share these extensions. The cloud IDE provides built-in extensions to the code-server implementation of Visual Studio Code for the web.
Anypoint Platform requires a user account. You can use an existing account or create one from Anypoint Platform in the US or EU cloud (see US and EU Cloud Hosts). Unexpired trial accounts are allowed.
If you decide to uninstall Anypoint Extension Pack, follow the same procedure that you use for other VS Code extensions. Uninstalling the extension pack also uninstalls the individual Anypoint Code Builder extensions that are bundled within the extension pack, such as the DataWeave and APIkit extensions.
