+This threshold guides the library into using a list based or a
+hash-table based descriptor for global to local index conversion;
+if the size of the global index space is below this threshold, a list
+based structure is used, if it is above a hash-table based structure
+is used. 
 Note: the threshold value is only queried by the library at the time a
 call to \fortinline|psb_cdall| is executed, therefore changing the threshold
 has no effect on communication descriptors that have already been
