[mpich-discuss] MPI_INIT_THREAD doesn't work properly under windows

[trymelz trymelz]

I see your point. I will change it to

elseif(plevel . e. I_THREAD_SERIALIZED)then

Thanks.

Even then you might not get what the code below expects.   The "provided" parameter can return a higher level of thread safety than requested, which is not an error, and should allow the application to proceed.

Hi,
 
I have a mixed-language programming project using C and FORTRAN. In the FORTRAN file, I have the following code
 
        call MPI_INIT_THREAD(MPI_THREAD_SERIALIZED,plevel, impierr)
        if(impierr.ne.MPI_SUCCESS)then
          write(*,*)'MPI is not initialized, exit'
        elseif(plevel .ne. MPI_THREAD_SERIALIZED)then
          write(*,*)'MPI LEVEL ERROR,exit',plevel
        endif

I compiled this project with VC6 and Intel Fortran compiler. When I run it, I get
 
 MPI LEVEL ERROR,exit           0
 
 
It seems to me that the MPICH2 doesn't support MPI_THREAD_SERIALIZED under windows.  I did not find any notes about this on the manual, so I am wondering if I am missing something important. Thanks.
