Hi, How have you been turning "networking on/off" ?
I have been testing this using a local version of head-of-tree (soon to be openmpi 2.0.2). This is head-of-tree as of Nov 25, with some local fixes needed for Debian - adding libpmix* which was not fully included; For me, the test case fails as advertised for unstable, works for me (tm). I'm uploading my working version to experimental for further tests. regards Alastair On 01/12/2016 15:04, Thibaut Paumard wrote: > Hi, > > I have made a couple of additional tests. > > I have run > mpirun --mca btl_tcp_if_include lo --mca btl tcp,self -np 2 \ > --mca plm_rsh_agent /bin/true slave > under a variety of environments.
