[mpich-discuss] 32-bit and 64-bit nodes cannot communicate with MPICH2

[Ivan Ivanov]

Hello, I am developing a simple cluster which has both 32-bit and 64-bit 
nodes. For MPI communication I use MPICH2. Communication between only 
the 32-bit nodes works, and communication only between the 64-bit nodes 
works. However, I cannot make a 32-bit node communicate with a 64-bit. 
When I run mpirun the command hangs because when the 32-bit node sends 
information, the 64-bit one cannot receive it. How can I fix that?

Thank you in advance!!!
