	| CHECK			| DESCRIPTION				| Functions Applied	|
	+-----------------------+---------------------------------------+-----------------------+
	| Call Consistency 	| Ensures that all processes in the 	| All Functions.	|
	|			| communicator have made the same	| (see notes 2 & 3)	| 
	|			| call in a given event.		|			|
	+-----------------------+---------------------------------------+-----------------------+
	| Root Consistency	| Ensures that all processes in the 	| Gather, Gatherv, 	|
	|			| communicator have given the same root.| Scatter, Scatterv,	|
	|			|					| Reduce.		|
	+-----------------------+---------------------------------------+-----------------------+
	| MPI_IN_PLACE 		| Ensures that all processes have either| Allgather, Allgatherv |

Things That Are Not Being Validated
(need implementation specific help):

	+-----------------------+---------------------------------------+-----------------------+
	| CHECK			| DESCRIPTION				| Functions Afflicted	|
	+-----------------------+---------------------------------------+-----------------------+
	| Group Consistency	| This cannot be checked becuase there	| Comm_create		|
	| 			| is no way to send group data in MPI.	|			|
	| 			| 					|			|
	+-----------------------+---------------------------------------+-----------------------+

	These functions require implementation specific details and are not included in the 
	library due to portability issues.  Mainly for reference.
