[OMPI devel] mca_base_component_distill_checkpoint_ready variable

[Adrian Reber]

There is a variable in the FT code which is not defined and therefore
currently #ifdef'd out.

#if (OPAL_ENABLE_FT == 1) && (OPAL_ENABLE_FT_CR == 1)
#ifdef ENABLE_FT_FIXED
    /* FIXME_FT
     *
     * the variable mca_base_component_distill_checkpoint_ready
     * was removed by commit 8181c8273c486bba59b3dead324939eac1a58b8c (r28237)
     * "Introduce the MCA framework system. This formalizes the interface 
frameworks must provide."
     *
     * */
    if (mca_base_component_distill_checkpoint_ready) {
        open_only_flags |= MCA_BASE_METADATA_PARAM_CHECKPOINT;
    }
#endif /* ENABLE_FT_FIXED */
#endif  /* (OPAL_ENABLE_FT == 1) && (OPAL_ENABLE_FT_CR == 1) */


The variable 'mca_base_component_distill_checkpoint_ready' used to exist but 
was removed
with commit 'r28237':

-#if (OPAL_ENABLE_FT == 1) && (OPAL_ENABLE_FT_CR == 1)
-    {
-        int param_id = -1;
-        int param_val = 0;
-        /*
-         * Extract supported mca parameters for selection contraints
-         * Supported Options:
-         *   - mca_base_component_distill_checkpoint_ready = Checkpoint Ready
-         */
-        param_id = mca_base_param_reg_int_name("mca", 
"base_component_distill_checkpoint_ready",
-                                               "Distill only those components 
that are Checkpoint Ready", 
-                                               false, false,
-                                               0, &param_val);
-        if( 0 != param_val ) { /* Select Checkpoint Ready */
-            open_only_flags |= MCA_BASE_METADATA_PARAM_CHECKPOINT;
-        }
-    }
-#endif  /* (OPAL_ENABLE_FT == 1) && (OPAL_ENABLE_FT_CR == 1) */

The variable is defined in contrib/amca-param-sets/ft-enable-cr

mca_base_component_distill_checkpoint_ready=1

Looking at the name of other variable I would say it should be called

opal_base_distill_checkpoint_ready

and probably created with mca_base_var_register() or 
mca_base_component_var_register().

What would be the best place to create the variable so that it can be used 
again in
the FT code?
