Many of our clients do not realize their TotalCAE HPC system is running Linux, since TotalCAE makes this all invisible to the engineer with just a few clicks to solve their applications through the TotalCAE platform web browser interface.

However 2020 marks the end of life for Red Hat Enterprise Linux 6, which has been out for 10 years now, and has a few remaining clients still on this version. Red Hat Enterprise Linux 7 is the most widely adopted and supported platform for TotalCAE clients on HPC clusters and cloud. The latest Red Hat Enterprise Linux 8 is not widely supported yet by all the CAE vendors, and we are not currently deploying RHEL8 for this reason.

For clients with legacy HPC clusters, this list is helpful in planning the last release of your software that you can go to until you replace the HPC system with an updated TotalCAE system, or TotalCAE cloud on AWS or Azure. TotalCAE supports over 100 applications listed here , so this is not a comprehensive list just ones that we have seen with some clients on legacy HPC systems so far that we have documented for them.
