Hmmm...given the interconnection between the OMPI and PMIx/PRRTE codes, and that they both utilize the MCA architecture, I wonder if we will create confusion if we don't bring this across to the others? There is no connection between MPI_T and those other codes, so if that is the primary motivator here, then perhaps it is less of an issue? Just pondering - if we want to maintain the similarity, then it doesn't seem like it would take much to do the port. |

@rhc54 Just depends on if this is useful. From an external perspective these are just strings like today. Internally the parsing is just handled inside the MCA base to avoid boilerplate code for parsing these. It may still be worth porting over to prrte if that still uses MCA given it centralizes the include/exclude logic. We did this with enums as well-- used to have a lot of code taking an int or string and converting it to a string or int. |

I am cleaning this one up a bit. Hold off on reviews. Adding support for regex include lists since I have a need for that. |
It is not uncommon in Open MPI to register a string variable to allow specifying an exclude or exclude list (every framework registers one). Given this common patten it is worthwhile to formalize an MCA include list variable type: MCA_BASE_VAR_TYPE_INCLUDE_LIST. Variables of this type use a new opal object (mca_base_var_include_list_t) that stores and argv-style array and an exclude- list flag. To register an include list variable the caller must first either OBJ_CONSTRUCT the object or allocate it with OBJ_NEW. Variables of this type are exposed as strings to MPI_T.

Ok, ready to go. |
