Greetings,
I'm having trouble getting openmpi 2.1.2 to work when launching a
process from debian 8 on a remote debian 9 host. To keep things simple
in this example, I'm just launching date on the remote host.
deb8host$ mpirun -H deb9host date
[deb8host:01552] [[32763,0],0] ORTE_ERROR_LOG: Error in file
base/plm_base_launch_support.c at line 954
It works fine when executed from debian 9:
deb9host$ mpirun -H deb8host date
Sat Jul 21 13:40:43 CDT 2018
Also works when executed from debian 8 against debian 8:
deb8host:~$ mpirun -H deb8host2 date
Sat Jul 21 13:55:57 CDT 2018
The failure results from an error code returned by:
opal_dss.unpack(buffer, &topo, &idx, OPAL_HWLOC_TOPO)
openmpi was built with the same configure flags on both hosts.
--prefix=$(PREFIX) \
--with-verbs \
--with-libfabric \
--disable-silent-rules \
--with-hwloc=/usr \
--with-libltdl=/usr \
--with-devel-headers \
--with-slurm \
--with-sge \
--without-tm \
--disable-heterogeneous \
--with-contrib-vt-flags=--disable-iotrace \
--sysconfdir=$(PREFIX)/etc \
--libdir=$(PREFIX)/lib \
--includedir=$(PREFIX)/include
deb9host libhwloc and libhwloc-plugins is 1.11.5-1
deb8host libhwloc and libhwloc-plugins is 1.10.0-3
I've been trying to debug this for the past few days and would
appreciate any help on determining why this failure is occurring
and/or resolving the problem.
