No, MPICH bundles its own version, and it would make packaging brittle to require that it match versions with openucx in [extra].

Does --with-device=ch4:ucx make openucx a runtime dependency of this package ?

Note that there is currently a sort of soft conflict with intel-oneapi-compiler-shared-runtime. One can comment the conflicting paths in /etc/ld.so.conf.d/intel-oneapi-compiler-shared-runtime-libs.conf as a work-around (though that may affect intel-oneapi).

Version 4.2.2 is available

In order to compile this I had to add -Wno-error=enum-int-mismatch to CFLAGS/CXXFLAGS and add a missing #include <cstdint> include to modules/ucx/test/apps/sockaddr/sa_util.h.

In my opinion, it's a good idea. MPI support for Intel GPUs seems like a very esoteric thing. The flag is --without-ze, I believe.

jedbrown commented on 2022-12-08 20:54 (UTC)

Should we add --remove-ze to configure flags for everyone so this problem doesn't come up?

For the benefit of anyone who stumbles into the following error:

Fatal error in internal_Init_thread: Other MPI error, error stack:
internal_Init_thread(60): MPI_Init_thread(argc=0x7fff4b9e1a60, argv=0x7fff4b9e1aa0, required=3, provided=0x7fff4b9e19b8) failed
MPII_Init_thread(205)...:  gpu_init failed
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=671731471
:
system msg for write_line failure : Bad file descriptor

This happens if you have Intel Level Zero library installed (at mpich compile time), but no Intel GPU at your code's run time.

The easiest fix is to add --without-ze to the configure flags.

openucx may be a dependency. I needed it to compile.
