Login Node Stability Issues on Ascend

OSC Classroom Support

CLASSROOM RESOURCES FOR DISTANCE LEARNING If your class has lost or limited access to computer labs, the Ohio Supercomputer Center might be able to help by providing no-cost access to cloud computing resources. Classes and workloads of any size can gain access. OSC's web-browser interface to its substantial Linux computer systems provides novice users with virtual desktops preloaded with applications, such as MATLAB, RStudio, or Jupyter Notebook. As an example, an OSU undergrad statistics class recently used iPads to remotely access RStudio on OSC systems.
