FYI, here is a command line which successfully computes a kernel using
bwc's interleaving:

./linalg/bwc/../.././build/fondue.mpi/linalg/bwc/bwc.pl  :complete
matrix=/local/rsa768/mats/rsa100.bin nullspace=left wdir=/tmp/bwc
thr=2x2  mpi=2x2 mn=128 ys=0..128 interleaving=1
hosts=fondue,raclette,tartiflette,berthoud mpi_extra_args="--mca
btl_tcp_if_exclude lo,virbr0" interval=200

(mpi is openmpi 1.6.1 here).
