[mpich-discuss] MPI_Recv crashes with mpd ring

[Bill Rankin]

Basically, ssh does not have the public host keys for the remote hosts and it is asking you for them.   Look at the manual page for "ssh-keyscan" for more information.

Hope this helps,

Hi Dave,



I had 1.2.1p1 built locally. So, I tried that. It also gave me same fatal error. I will try newer version, but I am less hopeful.





I am trying to use hydra (mpiexec.hydra) with 1.2.1.p1, but getting some startup errors:



The authenticity of host 'XXX' can't be established.

RSA key fingerprint is ed:ce:ca:7b:08:b9:49:fd:f6:af:14.

Are you sure you want to continue connecting (yes/no)?

The authenticity of host 'XXX2' can't be established.

RSA key fingerprint is fb:1b:7b:0c:bb:b1:a6:b1:7d:dc:05.



Any pointers how to resolve them?



Regards,

Rohit
