I did this, but output is a bit unclear to me. For example it has lines like
[j-053:221827] mca: base: components_register: found loaded component sm and in the same node, same process reports, [j-053:221827] coll:find_available: coll component sm is not available Does this mean SM is not available? If so, how can I build this component and make it available?
