Hello,I'm using CUDA-aware OMPIv4.0.3 with UCX to run some apps. Most of them have worked seamlessly, but one breaks and returns the error:memtype_cache.c:299 UCX ERROR failed to set UCM memtype event handler: Unsupported operation--
Hello,
My system is running CentOS8 & OpenMPI v4.1.0. Most stuff is working fine
but one app is aborting with:
MPI_ABORT was invoked on rank 7 in communicator MPI_COMM_WORLD
with errorcode 1734831948.
The other 23 MPI ranks also abort. I'm a bit confused by the high error
code. Does it mean anythi
Hi Jeff. Sorry for the delay. It took a while but I was finally error to
track down the point where the app breaks down. The problem seems to
originate in an output subroutine, not because any MPI communication is
malfunctioning. My guess is that MPI_Abort needs to produce some error
message. Why
The app is not calling MPI_ABORT directly. I dug a little deeper into it
but didn't find anything interesting. It just doesn't find the subdirectory
for output purposes (the internal error variable is 0) and simply crashes
when returning from the subroutine. It was just me not setting things up

Thanks,
Arturo

Hello,
This is kind of an odd issue as it had not happened earlier in many builds.
The configuration (./configure --with-ofi=PATH_TO_LIBFABRIC installed from
https://github.com/ofiwg/libfabric) for v4.1.1 returns:
