Subject: [OMPI users] can't understand the mean of "ofud" in openmpi
From: ãÛÊ¥ÕÜ (ksz_at_[hidden])

  When I use openmpi mpirun --mca btl <arg1>, I find arg1 can be ofud, self, sm, openib, but desn't explain those args. I can't understand the mean of "ofud", what different between "ofud" and "openib",
  I also can't understand the different between "ibcm" and "rdmacm", when I use mpirun --mca btl_openib_cpc_include <arg2>.
  maybe can publish a openmpi's document to explain those args and principle.
  wish your answer, best wish!
