[petsc-users] proper Fortran usage for PetscMemoryGetMaximumUsage

[Anthony Paul Haas]

Hi,

Could you please tell me what is the proper Fortran usage for
*P*etscMemoryGetMaximumUsage?
Do I need to define mem (see below) as PetscInt or PetscLogDouble? I tried
both and in both case I got zero memory for all the processes.

I did:

       1st try:  PetscLogDouble mem
       2nd try:  PetscInt mem

    call SlepcInitialize(PETSC_NULL_CHARACTER,ierr)


    call MPI_COMM_SIZE(MPI_COMM_WORLD,size,ierr)

    call MPI_COMM_RANK(MPI_COMM_WORLD,rank,ierr)


    call PetscMemorySetGetMaximumUsage(ierr)



    .... some code with allocate, MatCreate, MatsetValues,...


    call PetscMemoryGetMaximumUsage(mem,ierr)


    write(*,*)'On Processor',rank,'memory:',mem



Thanks,


Anthony
