Intel OneAPI 2025.2.1

NVIDIA HPC SDK 25.9

GCC 14

Product End-of-Life Notification

\ \

In lieu of the emerging Next Generation Programming Experience (NGPE), the HPE Cray Supercomputing Programming Environment (CPE) will reach its final release with CPE version 26.03. After this release, no further CPE versions will be issued. However, HPE will support CPE 26.03 for 15 months after that final release, providing production-critical fixes only and only for CPE components that are not being carried forward into the Next Generation Programming Experience. No renewals or extensions beyond current contractual agreements will be available after the 15-month support period ends.

What this means for you: If you are running CPE, you will have a stable, supported version (26.03) and a defined 15-month window for receiving critical fixes after final release. Non-critical updates, feature development for supported components, and long-term fixes will be provided in the Next Generation Programming Experience rather than in CPE. Existing CPE “recipes” will continue to be supported, where it depends on other products; support for each recipe will follow related product dependencies and lifecycles.

Note: HPE, at its sole discretion, reserves the right to consider product enhancement for sustainment purposes during the product’s EOL process.

For questions about the timeline, migration planning, or how this impacts your contract, please contact your HPE account team or support representative.

Documentation

NOTE: As of CPE 24.11 and later, HPE discontinued providing CPE release announcement and user guide documentation on the HPE Support Center web page. CPE 24.11 (and later) release announcement and user guides, along with installation guides, are now available on the CPE Documentation site. CPE installation guides for all CPE versions can still be accessed from the HPE Support Center web page. CPE 24.07 and earlier documentation, including user guides, installation guides, release announcements, and related revision documentation, can also be found on the HPE Support Center web page.

IMPORTANT NOTES

NOTE: Update to HPE Cray XD2000 Gen 10 Plus Setup Scripts. The setup scripts for HPE Cray XD2000 Gen 10 Plus systems, located in the cray-pe-profile package, have been updated to look for CPE’s provided Lmod package inside the CPE namespace (/opt/cray/pe). The setup scripts are responsible for how CPE behaves on a system. Please use caution when installing, so that the systems current settings in /etc/cray-pe.d/cray-pe-configuration.sh and /etc/cray-pe.d/cray-pe-configuration.csh are not lost.

NOTE: MPIs other than cray-mpich may not work on systems with Cray Programming Environment installed.

NOTE: Potential issue with libfabric and MOFED 5.8. When using the OFI netmod of Cray-MPICH there is a potential issue when calling MPI_Finalize which causes the application to seg fault. This is seen at 64 ranks and larger. If encountered, setting the environment variable FI_VERBS_PREFER_XRC=0 will allow for applications to finish. Note that there is a significant performance penalty at scale when setting this environment variable.

NOTE: The Red Hat GCC Toolset provides the cc compiler driver that will conflict with the craype driver. To ensure the environment’s PATH is correct, the craype module should always be reloaded after swapping or reloading the gcc-native module. You may run cc –craype-help to verify the correct executable is resolved.

NOTE: Perftools 26.03.0 and PAPI 7.1.0.4 included with CPE 26.03 are not compatible with ROCm earlier than 6.0.0, they require the use of ROCm 6.0.0 or later.

NOTE: Beginning in CPE 24.11, the NVHPC modules (PrgEnv-nvhpc, nvhpc, nvhpc-mixed) are no longer offered. The NVIDIA modules (PrgEnv-nvidia, nvidia, nvidia-mixed) are now the sole option for modules regarding the NVIDIA programing environment. The move to the NVIDIA modules is to complete the alignment of CPE module flows. The module flow for all environments is as follows:

Load an environment meta module (ie. PrgEnv-nvidia)

Environment meta module loads a compiler (ie. nvidia)

User can choose to load a toolkit (cuda, cudatoolkit)

NOTE: The March 2026 release will be the last RHEL 8.10 ESR.

NOTE: With CPE 26.03 (and later versions), SHMEM development, support, and maintenance has been removed from CPE and is now included and supported with the HPE Slingshot SHMEM Software product offering. To access information and download instructions for SHMEM, refer to the HPE Slingshot SHMEM Software Installation Guide (S-9030).
