Hi HPC users,<br>
<br>
We are well into planning for our 2026 HPC cluster upgrade. The upgrade remains on schedule for the first week of August (August 3 - 7, 2026). We have some important compiler updates to share.<br>
<br>
As part of this upgrade, we are updating our supported software stack. Please review the following compiler changes, as they may require you to recompile your custom code.<br>
<br>
The complete list of planned compiler versions is:</div>
