I tried rebuilding libfabric using kdreg=no and unloading cray-mpich module
./configure --disable-verbs --disable-sockets --disable-usnic --disable-udp --disable-rxm --disable-rxd --disable-shm --disable-mrail --disable-tcp --disable-perf --disable-rstream --enable-gni --prefix=/apps/daint/UES/biddisco/gcc/8.3.0/libfabric --no-recursion --enable-debug --with-kdreg=n
the binaries look sensible

but running pingpond on two compute nodes gives the same memory registration error. I don't understand what has changed on our system and why what used to work, doesn't any more. Is it ok to launch jobs by hand, or do they have to be part of an srun script - here I am manually sshing into two compute nodes and executing
pingpong from one and pingpong addr from the other. I'm suspecting some strange permission error because of the message
libfabric:69550:gni:mr:__mr_cache_search_inuse():1205<debug> [69550:1] could not find key in inuse, key=2aaaadbd5000:c01000
If anyone has any idea what might be wrong, please let me know. thanks.

Phil - thanks for this info. I will experiment with it. I'm actually away for a few days from tomorrow, so it'll be next week before I get a chance, but I'll report back if I have success (or more problems).

Hi John,
I know your question is aimed at Howard, but I can offer another data point and an example of a software stack working around this. I've never gotten kdreg to work in executables that are also using Cray's MPI; they conflict. If you want to use udreg as an alternative, then you'll need to do two things:
a) disable kdreg support in libfabric at build time (as in this spack package here: https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/libfabric/package.py#L94)
b) explicitly enable and configure udreg outside of libfabric (as in the Mercury libfabric plugin here: https://github.com/mercury-hpc/mercury/blob/master/src/na/na_ofi.c#L1778)
This configuration is stable for us and works fine whether Cray MPI is present or not. I'll defer to Howard about the technical implications, though 🙂
thanks,
-Phil

From the phrasing "You are hitting a limitation with the ancient kdreg device driver. It may be best to not use it for your libfabric app." is there anything I can do about it. I can see that there is a udreg directory in /opt/cray - is there anything I can replace the kdreg stuff with?
Thanks

my config line has always been this (apart from the debug). It has worked for several years until a recent system maintenance.change or something of that kind. (Nobody here claims to have changed anything significant)
./configure --disable-verbs --disable-sockets --disable-usnic --disable-udp --disable-rxm --disable-rxd --disable-shm --disable-mrail --disable-tcp --disable-perf --disable-rstream --enable-gni --prefix=/apps/daint/UES/biddisco/gcc/8.3.0/libfabric CC=/opt/cray/pe/craype/default/bin/cc CFLAGS=-fPIC LDFLAGS=-ldl --no-recursion --enable-debug

Hi John,
You are hitting a limitation with the ancient kdreg device driver. It may be best to not use it for your libfabric app. What are the configure options you're using for building libfabric?

I've got this log when I dump out my own messages, and also enable debugging in libfabric - can anyone tell what's wrong from the message. Code that used to work seems to have stopped. I upgraded to libfabric 1.10.1 tag and rebuilt, but it didn't change.
The only thing that springs to mind is that the application is also using MPI on the cray at the same time, so when this code is called, mpi_init would have already been called, and perhaps somehow the nic is inaccessible - hence the error. I'm sure it used to work - and if I use ranks = 1 - it runs - so perhaps mpi detects just one rank and does no initialization, but when I use N>1 ranks, it dies. Any suggestions welcome. Thanks
