[Medbionode] RStudio Server sessions

Dear RStudio Server users, please use the following recommendations for smooth work with RStudio Server, as well as avoiding potential issue for you or possibly causing disturbance to other users too on our MedBioNode cluster. Thanks very much in advance. To ensure the login node remains stable and responsive for everyone, please follow these guidelines when using the Open Source RStudio Server web interface. 1. Always use "Sign Out" — Don't just close the tab * The Problem: If you close your browser tab or laptop lid without logging out, your R session stays running in the background on the HPC login node. If you reconnect later from a different network, device, or browser, a duplicate session is created. This wastes system memory and slows down the cluster. * The Solution: When you are done working for the day, click the Sign Out button in the top-right corner of the RStudio window. This safely terminates your background processes. 2. Clean up your environment before leaving Before signing out, it is highly recommended to clear your R workspace to prevent bloated session files that slow down your next login: * Run rm(list = ls()) in your console to clear memory. * Go to Tools -> Global Options -> General and change “Save workspace to .RData on exit” to Never. This stops RStudio from saving massive, fragmented files to your home directory, which can cause your next session to hang on startup.
