We are having consistent failures in `direct-nm` configuration that looks very similar to the `am-only` failures reported in this issue. The details are pasted here and we are going to...

For send-recv am opearations, the solution is to have an alternative lmt protocol where the sender sends data in multiple segments and the recver do `MPIR_Typerep_unpack` for each segment. It...

The `cmake` log tells nothing about what went wrong during mpich build.

I believe the dependency is picked up by `hwloc`. `hwloc` currently will pick a few libraries including `cuda`, `opencl`, `nvml`. I suspect mpich don't really depend on the features. @raffenet...

@SiebertChris Hi Christian, thanks for pointing out the inefficiency in our MPI_Comm_split algorithm. You are right that we should adopt a simple parallel sorting algorithm. For reference, this issue has...

We have not gone through the MPI-IO code to ensure all its internal code works with large integers yet. All the non-IO large count functions should work as expected. Thanks...

Many of the higher level internal functions are still using `int`, for example ``` int MPIOI_File_write_ordered(MPI_File fh, const void *buf, int count, MPI_Datatype datatype, MPI_Status * status); ``` Someone need...

The CVAR description block can add an option called `config`; then the script, `maint/extractcvars.in`, can be made to accept a command-line option to only select those CVARs with matching config...

@raffenet Do you have examples why it may be necessary or desirable to exclude CVARs from ch3 or ch4?
