Hello Ludovic,

Apparently at the mpich configuration level, using the experimental
device ch4 instead of ch3 solves the problem : just remove comment on
"--with-device=ch4:ucx".  Reversely, with mpich 3.4a2 (for which ch4 is
de default) setting --with-device=ch3 leads to the same failure as with

I also checked sock channel for ch3 : with-device=ch3:sock, but then on
my laptop, scotch tests hang at

mpirun -n 3 ./test_scotch_dgraph_check data/bump.grf

For the moment, there isn't a stable 3.4 version yet for mpich. I had a
try with the latest 3.4b1 but a test failed...
