    Hi Everyone,

    <br>specifically aiming to enable RMA (Remote Memory Access) calls for efficient parallel computing. However, I've encountered some challenges in achieving the desired setup.

    <br>I have attempted multiple configurations, but it seems that the RMA calls of OFI are not being utilized based on my backtracing results. I am seeking your guidance to resolve this issue. Here are the configurations I've tried:

   <div class="default-style">

    <br><strong>1. ./configure --prefix=/home/<username>/mpich/mpich_exe --with-ch4-ofi-direct-provider=<provider> --with-libfabric-lib=/home/<username>/libfabric/libfabric_exe/lib --with-libfabric-include=/home/<username>/libfabric/libfabric_exe/include</strong>

   </div>

   <div class="default-style">

    <br><strong>2. ./configure --prefix=/home/<username>/mpich/mpich_exe --enable-ch4-am-only --with-ch4-ofi-direct-provider=<provider> ---with-libfabric-lib=/home/<username>/libfabric/libfabric_exe/lib --with-libfabric-include=/home/<username>/libfabric/libfabric_exe/include</strong>

    <br><strong></strong>

   <div class="default-style">

    <strong>3. ./configure --prefix=/home/<username>/mpich/mpich_exe --enable-mpit-pvars=rma --with-ch4-ofi-direct-provider=<provider> ---with-libfabric-lib=/home/<username>/libfabric/libfabric_exe/lib --with-libfabric-include=/home/<username>/libfabric/libfabric_exe/include</strong>

    Despite these attempts, the RMA calls from OFI are not being utilized as indicated by my analysis with Valgrind.

    <br>I kindly request your expertise and assistance in resolving this matter. If there are specific configurations or steps that I might be missing, please provide guidance on how to properly enable RMA calls using OFI in the MPICH setup.

    <br>Thank you for your time and support. I am looking forward to your valuable insights and suggestions to help me overcome this issue.
