[mvapich-discuss] about MPI_THREAD_FUNNELED

[Jia Jianfeng]

Hi, everyone, 


I compile mvapich-1.8.1 with configure as following.

./configure --enable-f77 
--prefix=/opt/mvapich2-1.8.1  --disable-mcast 
--with-ib-include=/usr/include/infiniband --with-ib-libpath=/usr/lib64 
--enable-threads=multiple --enable-threads=funneled

After compiled, when running, It give me a error as following,

 MPI error 0 in MPI library does not support the requested level of threading (MPI_THREAD_FUNNELED).

It
 seems that the MPI_THREAD_FUNNELED is not supported by mvapich2, isn't 
it? But why in the configure of mvapich2 have the option of   
--enable-threads=funneled??

Anybody any idea?
