[mpich-discuss] MPICH 3.4.1 and macOS 11.2 (aka Big Sur)

[Zhou, Hui]

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              \

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
0   libpmpi.12.dylib                    0x00000001068c2159 MPL_backtrace_show + 57

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
