Trouble running MPP Ls-Dyna 10.20 on a Red Hat 8,4 cluster

      One research group here in the College is having issues with LS-DYNA 10.2 .
      They are using the MPP version of LS-DYNA 10.2, and when our HPC cluster was upgraded in August from CENTOS7 to Red Hat 8,4 , the 10.2 binary started giving

      "*** buffer overflow detected ***

      errors . The research group that uses R10.2.0 is not able to switch to a new version,
      since the human body model they use only runs correctly using R10.2 with
      MPP. Updating the model to a new version is a fairly complex and time
      consuming task. This is not something they can do.

      I've attached an email from one of our HPC support people showing various things they have tried.

      Here is the exact version of LS-DYNA info

      Is there any support we can get with this issue from LSTC .



      Could we get a special recompile of 10.2 for Red Hat 8.4 ?
