[mvapich-discuss] MPI_Init_thread failed!

[Ji Wan]

Dear Developers,

I have an project which needs to using MPI functions in multiple threads,
so I have compiled `mvapich2-2.0rc2` using the following flags:

./configure LDFLAGS='-lstdc++' \
  --disable-f77 --disable-fc  \
  --enable-g=dbg --disable-fast \
  --enable-threads=multiple \
  --enable-cuda --with-cuda=/usr/local/cuda


At the beginning of my program, I have the following code:

  int provided;
  int ret = MPI_Init_thread(&argc, &argv, *MPI_THREAD_MULTIPLE*, &*provided*
);


But after this code executed, the value in *provided* is *MPI_THREAD_SINGLE*,
not *MPI_THREAD_MULTIPLE*.

Would you please giving some suggestion to this problem?

Best regards,
Wan Ji
