HOWTO: Use Address Sanitizer
Address Sanitizer is a tool developed by Google detect memory access error such as use-after-free and memory leaks. It is built into GCC versions >= 4.8 and can be used on both C and C++ codes. Address Sanitizer uses runtime instrumentation to track memory allocations, which mean you must build your code with Address Sanitizer to take advantage of it's features.
There is extensive documentation on the AddressSanitizer Github Wiki.
System Downtime May 19, 2020
A downtime for all OSC HPC systems is scheduled from 7 a.m. to 5 p.m., Tuesday, May 19, 2020. The downtime will affect the Pitzer, Ruby and Owens Clusters, web portals and HPC file servers. Login services, except for my.osc.edu, will not be available during this time. OSC clients are able to log into my.osc.edu during the downtime but no changes will take place until the downtime is completed.
In preparation for the downtime, the batch scheduler will begin holding jobs that cannot be completed before 7 a.m., May 19, 2020.
Software Refresh - May 2020
OSC will be refreshing the software stack for Owens and Pitzer on May 19, 2020. This will be done in a system-wide downtime. During the software refresh, some default versions will be changed to be more up-to-date. Information about the new default versions, as well as all available versions of each software package will be included on the corresponding OSC software webpage. See https://www.osc.edu/supercomputing/software-list.
Free Academic Ansys Desktop License (2020 R1 version)
Ansys, Inc. is generously providing a temporary free trial license for home use as a COVID-19 response for OSC academic users. You can download the installer and license from our website, see link below. The license will expire on May 31, 2020.
For more information, please visit our website (login required): https://www.osc.edu/resources/getting_started/howto/howto_install_free_academic_ansys_desktop_license_for_covid19
intel compiler module (gcc-compatibility) update
Previously, intel/19.0.3 and intel/19.0.5 compilers automatically load gcc-compatibility modules as following:
On Pitzer: gcc-compatibility/8.1.0 On Owens: gcc-compatibility/8.3.0
Now, gcc-compatibility/8.4.0 will be loaded consistantly. This has a very low impact, but if you have any issues, please contact OSC Help
Lower memory limits (Pitzer and Owens)
To improve system stability, the maximum allowed memory limit for jobs on owens and pitzer nodes is being reduced.
Some more details on why this change was made and exact memory limits can be found here:

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.
