Hello ZQ,</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
I am not able to reproduce this on cardinal. I was able to install mvapich through spack just fine with the spack installed versions of the oneapi compilers. The compiler versions I tested are 2024.0.2 and 2024.0.1 It looks like you were trying to use 2024.1
but I do not see that in spack. It may help to look at the compilers.yaml file to see if any flags are different or missing in it for this 2024.1. </div>
