<p style="margin:0px 0px 1.2em!important">I have added a command to print the linking info for the benchmark executable for each mpi build as per [1]. </p>
<p style="margin:0px 0px 1.2em!important">The results for benchmarks built with mpich@develop with gcc@8.3.0 are here [2] where the mpi_config file [3] has the ldd info printed out and I’m confirming that the right mpi library is being used. I don’t see any hcoll linking and can confirm that it is picking up the right mpich version. </p>
<p style="margin:0px 0px 1.2em!important">I have also printed out the linking info for mpich itself and attach the output of the following along with this email : </p>
