MPI_T_pvar_reset — Reset the value of a performance variable

#include <mpi.h>
int MPI_T_pvar_reset(MPI_T_pvar_session session, MPI_T_pvar_handle handle)


  • session: Performance experiment session.
  • handle: Performance variable handle or MPI_T_PVAR_ALL_HANDLES.

MPI_T_pvar_reset sets the performance variable specified by the handle in handle to its initial value. The special value MPI_T_PVAR_ALL_HANDLES can be passed in handle to reset all read-write handles in the session specified in session.

MPI_T_pvar_reset will fail if:

  • MPI_T_ERR_NOT_INITIALIZED: The MPI Tools interface not initialized
  • MPI_T_ERR_INVALID_HANDLE: The handle is invalid
  • MPI_T_ERR_INVALID_SESSION: Session argument is not a valid session
  • MPI_T_ERR_PVAR_NO_WRITE: Variable cannot be reset
