Launching the Desktop

When launching the desktop, it will not open immediatley. What is happening is that the system is allocating the hardware needed and then submitting a job to a compute node to run.

Once it is ready, you will see a green bar that says it’s running.

To actually launch the desktop, you have to click the Launch button on the bottom of the box

It is a good practice to keep the number of interactive sessions you are working on in check. As each of these are using resources on MedicineBow, if you have many open sessions that are idle, you will be preventing other users from using them.

You can free up those resources by cancelling your sessions using the “Cancel” button image-20240722-175448.png
