[mvapich-discuss] MVAPICH2 spawn problem

[Francisco Javier García Blas]

Hi all, 

I compiled mvapich2 0.9.8 with  ./make-mvapich.ofa and all seems to be  
well, but when i tried to run the spawn merge example something goes 
wrong. The result of the execution is this:

sh-3.00$ ../bin/mpdboot
sh-3.00$ ../bin/mpiexec -n 2 spawn_merge_parent
Parents spawning 2 children...
Fatal error in MPI_Comm_spawn: Other MPI error, error stack:

The spawn functionality works well for TCP/IP sockets over IB, it fails 
only with the Infiniband library. The Infinibad library is  ofed1.1

Do you have any idea what the possible problem might be?

Many thanks
