Hey everyone,
I am working for longer time now with cuda-aware OpenMPI, and developed longer
time back a small exceptions handling framework including MPI and CUDA
exceptions.
Currently I am using MPI_Abort with costum error numbers, to terminate
everything elegantly, which works well, by just
Jeff,
Thanks for the tip - it started me thinking a bit.
I was using a directory in my /home account with 4.1.5 that I had
previously built using GCC 9.4 (Ubuntu 20.04). I rebuilt the system with
Ubuntu-22.04 but I did a backup of /home. Then I copied the 4.1.5 directory
to /home again.
I checke
There were probably quite a few differences from the output of "configure"
between GCC 9.4 and GCC 11.3.
For example, your original post cited
"/usr/lib/gcc/x86_64-linux-gnu/9/include/float.h", which, I assume, does not
exist on your new GCC 11.3-based system.
Meaning: if you had run make clea
Alex,
How are your values "random" if you provide correct values ? Even for
negative values you could use MIN to pick one value and return it. What is
the problem with `MPI_Abort` ? it does seem to do what you want.

As soon as you pointed out /usr/lib/gcc/x86_64-linux-gnu/9/include/float.h
that made me think of the previous build.
I did "make clean" a _bunch_ of times before running configure and it
didn't cure it. Strange.
But, nuking the source tree from orbit, just to be sure, and then
configure/rebuild w
The GNU-generated Makefile dependencies may not be removed during "make clean"
-- they may only be removed during "make distclean" (which is kinda equivalent
to rm -rf'ing the tree and extracting a fresh tarball).

I don't know how openmpi does it, but I've definitely seen packages where "make
clean" wipes the ".o" files but not the results of the configure process.
Sometimes there's a "make distclean" which tries to get back closer to
as-untarred state.
Noam

Hey George,
I said random only because I do not see the method behind it, but exactly like
this when I do allreduce by MIN and return a negative number I get either 248,
253, 11 or 6 usually. Meaning that's purely a number from MPI side.
The Problem with MPI_Abort is it shows the correct number
