[mpich-discuss] problems with HYDRA on cygwin/win7?

[Ingo Bojak]

Hi all,

I'm trying to install the latest mpich2 (1.4.1) under Cygwin (updates to 
latest/complete version just prior) on Win 7. The aim is to run it on 
this single machine for program development, instead of on the cluster. 
Once the program works, it will get uploaded.

All goes to plan with the installation handbook, including having set up 
SSHD and public key so that

ssh mylocalhhostname date

actually spits back a date with no fuzz.

Upon typing however

mpiexec -f machinefile -n 5 ./examples/cpi

I get this:

Any ideas what this is about, and what I can do?

Thanks,
Ingo
