	I installed mpi on a DEC Alpha 3000/400 and tried to run 2 processes
communicating thru sockets to get an idea of how to use  the -p4pg 
option because I eventually would like to run mpi on a heterogeneous 
network. Here is my file

	morphy.che.utexas.edu 0 /home/schleize/mpich/examples/basic/cpi
	morphy.che.utexas.edu 1 /home/schleize/mpich/examples/basic/cpi
	morphy.che.utexas.edu 1 /home/schleize/mpich/examples/basic/cpi

Here is the command I used to run

	mpirun -p4pg many.file -np 2 cpi

and here is the msg that I got when I ran the program

	stty: tcgetattr: Permission denied
	stty: tcgetattr: Permission denied
	pi is approximately 3.141601, Error is 8.332923e-06
	wall clock time = 0.011719
	P4 procgroup file is many.file.

Does the stty msg mean that the computer cannot send a msg thru the network?
At any rate could someone tell me how to fix the problem. Thanks.
