The Message‐Passing Interface (MPI) is commonly used to write parallel programs for distributed memory parallel computers. MPI‐CHECK is a tool developed to aid in the debugging of MPI programs that are written in free or fixed format Fortran 90 and Fortran 77. This paper presents the methods used in MPI‐CHECK 2.0 to detect many situations where actual and potential deadlocks occur when using blocking and non‐blocking point‐to‐point routines as well as when using collective routines.
