[mpich-discuss] Fatal error in MPI_Barrier

Are you really trying to use the wireless network? Looks like that's what is getting used.
 
You can use the mpdcheck utility to diagnose network configuration problems. See Appendix A.2 of the installation guide.

I have two PC's with linux (kubuntu 8.10). I make a cluster using this machines. When use for example the command "mpiexec -l -n 2 hostname" i can see that it's all right, but when i try to send o receive some thing i have the same error. I don't know why. Please i need one hand. Thanks for all.
