Thanks - I’m up to the runtime failure on FI_ADDR_NOTAVAIL. Is there an alternative path to build MPICH on OSX? Bill William Gropp Director and Chief Scientist, NCSA Thomas M. Siebel Chair in Computer Science University of Illinois Urbana-Champaign

If you hit this runtime error:

Assertion failed in file src/mpid/ch4/netmod/ofi/ofi_init.c at line xxxx: mapped_table[i] != FI_ADDR_NOTAVAIL

That is due to libfabric having trouble with ipv6 addresses and it ignores our hints on addr_format. I'll work out a patch later.

Just updating from git is not enough to fix it, though. Since it is a submodule update, you'll need to run

git submodule update --init

to pull in the latest fix.

The particular link error should have been fixed since this Monday. Try make sure it is the correct source tree and clean build tree? That said, there will be additional run time issues building ch4 on mac. I’ll spend some time tomorrow and follow up if I can make progress.

Using the current as of this morning from git, hash 1d340282 , and with CC=gcc-10 (needed to work with the corresponding version of gfortran, because gcc on OSX is really clang)

../../sources/mpich/configure --with-device=ch4:ofi --prefix=/Users/gropp/installs/mpich2-dbg

works but make ends with

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: lib/.libs/libmpifort.a(mpi_c_interface_nobuf.o) has no symbols
