      Our clusters run CentOS 7 and our available compilers and
      libraries are more than three years old. It's pretty painful :)<br>
      <br>
      Luckily, the admins are receptive to an update and have a few
      ideas. This shouldn't be a huge deal for us.<br>

        <div>As an example, Ubuntu-18.04 should support it

          &gt; Hello GROMACS developers,<br>
          &gt;<br>
          &gt; we discussed some updates to the current compiler and
          standard library <br>
          &gt; requirements for GROMACS 2021 during the developer
          teleconference <br>
          &gt; yesterday that I also want to share with the broader
          community.<br>
          &gt;<br>
          &gt; Our plans are to require a C++17 standard compliant
          compiler starting <br>
          &gt; with GROMACS 2021, as well as a C++17 standard library.<br>
          &gt; If you think that the requirements for the standard
          library are too <br>
          &gt; harsh for older systems, we might work around this, but
          would then <br>
          &gt; still prefer updating the compiler requirements only.<br>
          &gt;<br>
          &gt; We are aware that this might be a quite large change to
          the current <br>
          &gt; requirements, so please let us know your comments about
          this.<br>
          &gt;<br>
          <br>
          Our sysadmins keep our compilers and libraries fairly
          outdated, so this <br>
          may be a big challenge for us. I can let them know about
          upcoming <br>
          requirements, but I do not know if they will provide new
          compilers and <br>
          the updated C++ library.<br>
