The Message Passing Interface (MPI) is widely used to write parallel programs using message passing. Due to the complexity of parallel programming there is a need for tools supporting the development process. There are many situations where incorrect usage of MPI by the application programmer can automatically be detected. Examples are the introduction of irreproducibility, deadlocks and incorrect management of resources like communicators, groups, datatypes and operators. This paper also describes the tool MARMOT that implements some of these tests. Finally the paper describes the experiences with three applications of the CrossGrid project regarding the usability and performance of this tool.
