I loaded mpich, version 1.1 (April, 1997) and installed it on my
worksatation with HPUX B.10.01 according to the instructions. 
But when testing it there was a problem. When doing

cd examples/test 
make testing

I got a lot of error messages saying

gethostbyname failed 100 times for host 0

Also, when I tried to run the supplied sample program with

cd examples/basic
make cpi
mpirun -np 4 cpi

I had no success for the same reason. However, I succeeded in running
this program by using another option of the mpirun command:

echo local 0 > test.pg
mpirun cpi -p4pg ../../test.pg

But the test program above ('make testing') still does not work,
although the file test.pg now exists, and I get the same error
messages. I could perhaps just proceed by always using the -p4pg
option, but I feel uncomfortable with all those error messages
from the test program.

Any help would be most welcome.
