<div dir="ltr">Hi,<div><br></div><div>I'm happy with the recent change to requiring 64-bit integers, but I note that this means we have required that the MPI library support the MPI_INT64_T datatype from MPI 2.2. AFAIK that's probably OK in practice, but I thought it worth mentioning / discussing.</div>
<div><br></div><div>We should update the install guide and add a CMake test for its support, however, since there will still be plenty of people with earlier non-compliant MPI libraries. I imagine CentOS will take about 5 years to update that far...</div>
