Does setting environment variable `MPIR_CVAR_OFI_SKIP_IPV6=1` work? -- Hui Zhou From: Eric Borisch via discuss <[email protected]> Date: Thursday, February 18, 2021 at 7:36 PM To: [email protected] <[email protected]> Cc: Eric Borisch <[email protected]> Subject: Re: [mpich-discuss] MPICH 3.4.1 and macOS 11.2 (aka Big Sur) 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. - Eric On Thu, Feb 18, 2021 at 3:59 PM Blaise A Bourdin via discuss <[email protected]<mailto:[email protected]>> wrote: Hi, Absolutely no issues here when using gcc10 from homebrew both on intel and ARM.

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 1 libpmpi.12.dylib 0x000000010684e874 MPIR_Assert_fail + 36 2 libpmpi.12.dylib 0x0000000106897bc8 MPIDI_OFI_mpi_init_hook + 4472 3 libpmpi.12.dylib 0x00000001068790d3 MPID_Init + 3091 4 libpmpi.12.dylib 0x00000001066ae70b MPIR_Init_thread + 219 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.
