Frontier and Crusher: System Software Upgrade (July 18, 2023)
The Crusher TDS and Frontier systems were upgraded to a new version of the system software stack. This stack introduces ROCm 5.5.1 and HPE/Cray Programming Environment 23.05. For more information, please see:
Please contact help@olcf.ornl.gov with any issues or questions.
Frontier: Darshan Runtime 3.4.0 (May 10, 2023)
The Darshan Runtime modulefile darshan-runtime/3.4.0 on Frontier is now loaded by default. This module will allow users to profile the I/O of their applications with minimal impact. The logs are available to users on the Orion file system in /lustre/orion/darshan/<system>/<yyyy>/<mm>/<dd>.
Unloading darshan-runtime modulefile is recommended for users profiling their applications with other profilers to prevent conflicts.
Please make a note of this change and contact help@olcf.ornl.gov with any issues or questions.

Ascent: Software Installation/Default Software Changes (February 7-11, 2022)
Ascent’s operating system will be upgraded to Red Hat Enterprise Linux 8 (RHEL 8) on February 7-11, 2022.
Warning
Codes should be rebuilt prior to running following the upgrade due to the OS and software changes.
As a result of the upgrade, the following new packages will become available:
| Package | Current Default | New Default |
|---|---|---|
| CUDA Toolkit | 10.1.243 | 11.0.3 |
| IBM Spectrum MPI | 10.3.1.2-20200121 | 10.4.0.3-20210112 |

Note
The OS-provided Python will no longer be accessible as python (including variations like /usr/bin/python or /usr/bin/env python); rather, you must specify it as python2 or python3. If you are using python from one of the modulefiles rather than the version in /usr/bin, this change should not affect how you invoke python in your scripts, although we encourage specifying python2 or python3 as a best practice.

All Systems: Python2 End of Life (January 01, 2020)
On January 1, 2020, Python 2 will reach its end of life and will no longer be supported by the project’s core developers. On this date, the OLCF will also end its support for Python 2. Users reliant on Python 2 should port code to Python 3 for forward compatibility with OLCF systems and many open source packages. Python 2 modules will not be removed on January 1, but will no longer receive maintenance or regular updates.
While default Python modules on OLCF systems are already set to Python 3, we recommend all users follow PEP394 by explicitly invoking either ‘python2’ or ‘python3’ instead of simply ‘python’. Python 2 Conda Environments and user installations of Python 2 will remain as options for using Python 2 on OLCF systems.
Official documentation for porting from Python 2 to Python3 can be found at: https://docs.python.org/3/howto/pyporting.html
General information and a list of open source packages dropping support for Python 2 can be found at: https://python3statement.org/
Summit: Software Upgrade (July 16, 2019)
The following modules will be installed and will become the default on July 16, 2019. The new stack requires Spectrum MPI 10.3 PTF 1 and as a result previous versions of Spectrum MPI have been deprecated.
| Package | Default |
|---|---|
| cuda | 10.1.168 |
| spectrum-mpi | 10.3.0.1-20190716 |
Details about the software stack upgrade can be found in the IBM Service Pack 3.1 site and the Spectrum MPI 10.3.0.1 release notes.
