Subject: Re: [OMPI devel] Deadlocks with new (routed) orted launch algorithm

I'm afraid Sylvain is right, and we have a bug in ompi_info:

              MCA routed: parameter "routed_binomial_priority" (current value: <0>, data source: default value)
              MCA routed: parameter "routed_cm_priority" (current value: <0>, data source: default value)
              MCA routed: parameter "routed_direct_priority" (current value: <0>, data source: default value)
              MCA routed: parameter "routed_linear_priority" (current value: <0>, data source: default value)
              MCA routed: parameter "routed_radix_priority" (current value: <0>, data source: default value)
              MCA routed: parameter "routed_slave_priority" (current value: <0>, data source: default value)

Those params do not exist in the code base. I think we -assume- that every component will have an MCA param for setting priority, but most of the ORTE ones do not.

We'll need to review ompi_info and fix this.

You might want to check your setup and see if they're being set via an unexpected mechanism...? Try using the "--parsable" switch and grep for "data_source" to see where values are getting set from.
