I'll patch our installation to crowbar that to 1 for now, if that seems reasonable. Thanks, - Eric On Fri, Feb 19, 2021 at 7:56 AM Zhou, Hui <[email protected]> wrote:
Does setting environment variable `MPIR_CVAR_OFI_SKIP_IPV6=1` work?

Blaise,
This is 3.4.1 and CH4?
With —enable-fast=all, asserts are disabled; can you see if it will compile and execute mpi binaries when built without that option? I suspect it will catch the invalid condition (with the non-elided assert), and would likewise crash if it was used in actual distributed (non-localhost) execution.
Let me know; if it doesn’t crash for you I would love to figure out why.

Hi,
Absolutely no issues here when using gcc10 from homebrew both on intel and ARM.
Here is my configuration options:
./configure --prefix=$MPICH_HOME \
--enable-fast=all,O3 \
--enable-g=dbg \
--enable-romio \
--enable-shared \
--enable-sharedlibs=gcc-osx \

Hello,
First post to the discussion board. I made the mistake of upgrading to macOS 11.2 (aka Big Sur). I was able to build MPICH 3.4.1 successfully and integrate it with an application. However, when I ran, MPICH crashed. Here is the initial output:
Abort(1) on node 0: Internal error

5 libmpi.12.dylib 0x00000001064bb897 MPI_Init + 279
I have not yet dug into the issue any further. Before doing so I wanted to first check to see if others have successfully built and run via macOS 11.2. If so I would appreciate any pointers. If it is known that it will not yet work, that would be good information as well so not to spend anytime digging.
I should note that on another machine, I was wiser and upgraded to macOS 10.5.7 (aka Catalina) and built and ran with 3.3.1 that worked fine running in parallel.
Cheers,
Allen
