MPICH and OPENMPI seem to have trouble nowadays and I'm not sure why. Here is a typical error:
patti@OS121-TY3:~/bor> /opt/mpich/ch-p4/bin/mpirun -np 4 pll.exe
p0_44650: p4_error: Could not gethostbyname for host OS121-TY3; may be invalid name
: 64
patti@OS121-TY3:~/bor> hostname
OS121-TY3
patti@OS121-TY3:~/bor>
...but in the body of my /etc/HOSTNAME file = OS121-TY3.MY-WORKGROUP
...so is the trouble with that dot extension? How can mpirun have trouble finding my hostname? I get a similar "Could not gethostbyname for host OS121-TY3" error with Openmpi's mpirun command. I have a single multiprocessor workstation - running Opensuse 12.2 x64
Thank you for any help!
