OSC enables Globus High Assurance storage endpoint

A new High Assurance Globus endpoint for OSC will be deployed to manage protected data on February 2, 2023. This will affect current projects at OSC which use Globus to manage their protected data. These projects will need to use the new High Assurance Globus endpoint to access their data. The name of the new endpoints are OSC /fs/ess High Assurance for project storage (/fs/ess) and OSC /fs/scratch High Assurance for scratch storage (/fs/scratch).

Changes on MPI libraries after Dec. 13, 2022 downtime

During the Dec. 13, 2022 downtime, we will upgrade MOFED from 4.9 to 5.6 and recompile all OpenMPI and MVAPICH2 against the newer MOFED version on Owens. After downtime, users with their own MPI libraries on Owens may see job failures and will need to rebuild their applications linked against the MPI libraries.

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.
