It is more trivial than this: mpirun -np 2 --mca
btl_tcp_rndv_eager_limit 0 --mca btl_tcp_eager_limit 72 --bynode ./
NPmpi ?
You would have a user do that rather than
mpirun --mca mpi_force_ssend 1 -np 2 --bynode ./NPmpi
?
I'm an OMPI implementor and I'll never remember that the TCP BTL
requires *2* eager limits, much less what their values are. :-)
